Abstract Background Cesarean scar pregnancy (CSP), a distinct form of ectopic pregnancy, presents challenges in effective management. It is categorized into three subtypes according to the location of placental implantation and the thickness of the myometrium at the uterine scar. Nevertheless, the optimal choice of treatment modalities for these subtypes remains largely unexamined. Methods In this retrospective analysis, we investigated the cases of 130 patients diagnosed with CSP who underwent diverse treatment approaches, namely ultrasound-guided dilation and curettage (D&C), hysteroscopic surgery alone or in combination with laparoscopic surgery (HCoLC), or uterine artery embolization (UAE) followed by curettage. Clinical data were meticulously retrieved from medical records and follow-up data, and a comparative analysis of relevant indicators was carried out across the different CSP subtypes. Results From January 2017 to December 2021, 35 patients underwent D&C, 85 underwent HCoLC, and 10 received UAE as a pretreatment. In the D&C group, the success rates for Type I and Type II CSP were 64.29% (18/28) and 14.28% (1/7), respectively. Significant differences were observed between the success and failure groups in terms of gestational sac size and clinical classification. Compared to Type I CSP, Type II CSP exhibited significantly longer surgical durations and higher hospitalization costs (P

Abstract Uterine arteriovenous malformation (UAM) is a rare medical condition. Even though UAM can cause abnormal and life-threatening uterine hemorrhage, there is no consensus on the clinical guideline on its treatments, most likely due to its low incidence, unknown etiology, and distinct fertility demands by different patients. Here, we present one elderly woman with uncommon UAM. We first discuss our experience regarding the diagnoses and treatments of UAM and then propose a hypothesis for the pathogenesis of UAM.

This study aimed to evaluate the safety and efficacy of emergency and prophylactic uterine artery embolization (UAE) in our clinical practice, including technical success, clinical success, and associated complications.

Abstract This review compares the efficacy of Uterine Artery Embolization (UAE) and Myomectomy (MYO) in managing symptomatic Uterine Fibroids (UFs) in women who do not want hysterectomy. A meta-analysis was performed on all available studies that evaluated the relative benefits and harms of MYO and UEA for the management of patients suffering from UFs. Outcomes evaluated reintervention, UFs scores for quality of life (QOL) and symptom severity, and other complications. To determine mean differences (MDs) or odds ratios (ORs) with 95% confidence intervals (CIs), a random or fixed-effects model was utilized. A meta-analysis of 13 studies (9 observational and 4 randomized controlled trials) was conducted. The results indicated that UAE had a higher reintervention rate (OR 1.84; 95% CI 1.62–2.10; P

Insufficient understanding of this condition among clinicians may result in delayed diagnosis and treatment, potentially leading to incorrect interventions and poor prognosis, including fatal hemorrhage and even necessitating hysterectomy in severe cases.Case Report: The patient, a 41-year-old woman with a history of three pregnancies and two deliveries, underwent cesarean section and subsequently experienced persistent small amounts of vaginal bleeding for a duration of two months. Transvaginal ultrasonography revealed a hypoechoic mass in the cervix that was initially misdiagnosed as a cervical fibroid. Approximately 12 h prior to admission, she experienced an episode of acute vaginal bleeding of significant intensity. Emergency transvaginal ultrasound demonstrated an intrauterine mass located in the posterior wall of the cervix with swirling blood flow, exhibiting a to-and-fro pattern. The mass was connected to the left uterine artery adjacent to the cervix through a tear measuring approximately 0.5 cm in diameter. Emergency bilateral uterine artery embolization was performed. After a follow-up period of ten months, there was no recurrence of abnormal vaginal bleeding, and subsequent ultrasound examination confirmed the complete resolution of the cervical lesions.Conclusion: The findings of this case suggest that the UAP undergoes a dynamic process. In the early stages, the lesion may manifest as a small hypoechoic or anechoic area within the myometrium. Color Doppler imaging might not reveal blood flow signals within the lesion, potentially leading to misdiagnosis as other common uterine lesions such as fibroids or cysts. However, considering the close association between UAP and the uterine artery, meticulous observation of the relationship between the uterine artery and its branches is crucial for identifying myometrial lesions to facilitate early detection of UAP and minimize misdiagnosis.Keywords: uterine artery, pseudoaneurysm, postpartum hemorrhage, ultrasound, uterine artery embolization

In an 8-year period at two medical center, 138 patients underwent uterine artery embolization, and 11 of them were diagnosed with uterine necrosis. Among them, three were successfully conceived. However, one of them developed an arteriovenous malformation after an artificial abortion, and another experienced complications, including placenta previa and placenta accreta spectrum, which resulted in early preterm delivery and recurrent postpartum hemorrhage, necessitating subtotal hysterectomy. Therefore, it is crucial to prepare for potential adverse pregnancy outcomes in subsequent pregnancies for patients with a history of uterine necrosis.

Aim. To evaluate the effect of uterine artery embolization (UAE) on reproductive health in women 40 years and older. Materials and methods. A retrospective study was conducted at the perinatal center of the District Clinical Hospital of Khanty-Mansiysk. Patients were divided into two groups: the main group (group 1; n=57) included women with uterine fibroids after UAE, and the control group (group 2; n=42) included women without a history of uterine fibroids. Results. Women with uterine fibroids were statistically more likely to have grade 1 obesity (χ2=4.39; p=0.04) and less likely to have normal body weight (χ2=8.73; p=0.00) compared to women without fibroids. Smoking increased the risk of uterine fibroids twofold (χ2=4.49; p=0.03; odds ratio 1.97; confidence interval 0.64-6.11). More women with uterine fibroids had a history of abortions (n=42; 73.7%) than those without uterine fibroids (n=19; 45.2%; χ2=8.27; p=0.01). The most common gynecological comorbidities in women with uterine fibroids included inflammatory disease of the uterus (N71), endometrial polyp (N84), and endometriosis (N80); p0.05. The most common extragenital diseases in patients with uterine fibroids included thyroid disease, hypertension, and iron deficiency anemia (p0.05). Contour SE embolization agent with spherical particles was more often associated with pain (χ2=0.18; p=0.67) and less often with fever (χ2=4.47; p=0.03). There was a decrease in the number of short menstrual cycles (less than 24 days) from the moment before surgical treatment and after 24 months (χ2=34.580; p0.001) and an increase in the number of cycles of 24–38 days (χ2=14.887; p=0.005). At 24 months after UAE, there were more women with a menstrual period of less than 3 days (χ2=10.385; p=0.035) and fewer with a menstrual period of more than 8 days (χ2=34.573; p0.001). Ultrasound showed a decreased ovarian reserve at 6, 12 and 24 months after UAE (p0.05). Conclusion. When assessing the reproductive health of women 40 years and older after embolization of the uterine arteries, it was found that this method of treatment of symptomatic uterine fibroids leads to a decrease in the duration and heaviness of menstruation but increases the risk of an ovarian reserve decrease.

Objective To evaluate the safety and feasibility of transumbilical single-port laparoscopic uterine artery embolization combined with incision and embryo retrieval in the treatment of cesarean scar pregnancy. Methods Eleven patients with cesarean scar pregnancy who underwent transumbilical single-hole laparoscopic uterine artery embolization combined with incision and embryo retrieval were recruited in the study group， and ten patients who underwent multi-hole laparoscopic uterine artery embolization combined with incision and embryo retrieval were assigned into the control group. Baseline data and perioperative clinical data were compared between two groups. Results No significant differences were found in age， number of pregnancies， number of cesarean sections， time interval from last cesarean section， clinical classification， number of days of menopause， and the presence or absence of symptoms of vaginal bleeding between two groups （all P > 0.05）. No significant differences were observed in operation time， intraoperative bleeding and postoperative retention time of catheterization between two groups （all P > 0.05）. In the study group， postoperative numeric rating scale （NRS） score was significantly lower and the length of hospital stay was significantly shorter compared with those in the control group （both P < 0.05）. Conclusions Compared with traditional multi-port laparoscopic uterine artery embolization combined with incision and embryo retrieval， transumbilical single-port laparoscopic uterine artery embolization combined with incision and embryo retrieval is a feasible and safe procedure， which can alleviate postoperative pain， shortern the length of hospital stay and yield better cosmetic results.

Background/Aims: Demonstration of possible utero-ovarian anastomoses (UOA) before or during uterine artery embolization (UAE) is important to preserve ovarian reserve. This study aimed to evaluate the incidence and risk factors for the presence of type 1b or type 3 UOA in patients undergoing UAE for the treatment of uterine myomas. Methods: Procedural angiographies of patients who underwent UAE were evaluated in a single academic center. Patients’ demographics, indication for UAE, presence and type of UOA, presence of adnexal pathology at preprocedural MRI, history of pelvic surgery, and total uterine volume at preprocedural MRI were retrospectively evaluated. Analysis of the aforementioned variables between patients with and without UOA was performed. Results: This study included 30 patients with a mean age of 41.97±5.72 years (range 32 - 56). UOA was found in 17 (56.6%) patients, 10 (33.3%) of them were type 1b, and 7 (23.3%) of them were type 3. Five patients (17.2%) had adnexal pathology at pre-procedural MRI and 12 patients (40%) had a history of pelvic surgery. The mean total uterine volume was 607.1 cm3. In the analysis of variables between patients with and without UOA, UOA presence was significantly higher in patients with a history of pelvic surgery (p=0.005). All of the patients with a history of myomectomy were found to have type 1b or type 3 UOA. No significant relation between UOA and age, the presence of adnexal pathology, and uterine volume were detected. Conclusion: Utero-ovarian anastomoses are commonly encountered during UAE. A history of pelvic surgery was found to be a risk factor for the presence of type 1b and type 3 UOA.

Background: The objective of this study is to assess the effectiveness of ultrasound-guided suction curettage (UGSC) in conjunction with or without high-intensity focused ultrasound (HIFU) or uterine artery embolization (UAE) for the treatment of three distinct types of cesarean scar pregnancy (CSP). Methods: This was a retrospective study that included subjects diagnosed with CSP in a single tertiary referral centre from January 2015 to December 2020. UGSC associated with/without pretreatment was offered to CSP patients according to the location of pregnancy sac, the depth of implantation and the surrounding blood flowing. The data about baseline characteristics and outcome parameters were analyzed across the three groups. Results: The present study included 434 patients diagnosed with CSP. The majority were cured without severe complication except one case accepted blood transfusion. The baseline data from the three groups did not differ statistically. The UGSC group had the same successful rate of treating type I CSP with a shorter hospital stay (χ2 = 51.771, p = 0.000) compared to the HIFU or UAE groups. Type II CSP presented marked less blood loss (Z = –2.464, p = 0.014) and higher decline ration of beta-human chorionic gonadotropin (β-HCG) (Z = –4.728, p = 0.000) in HIFU group. Treatment success was high in patients with type III CSP in both the HIFU and UAE groups, but the rate of β-HCG decline was higher in the HIFU group (Z = –2.255, p = 0.024). Conclusions: This study suggests that UGSC is an effective and safe option for patients with low-risk CSP. HIFU or UAE combined with UGSC has higher efficacy in high-risk CSP. And HIFU may be superior in reducing bleeding and increasing the rate of β-HCG decline.

Uterine artery embolization (UAE), a minimally invasive procedure used for controlling and managing profuse bleeding in conditions like uterine fibroids, and uterine hemorrhage, in cases of intractable postpartum hemorrhage (PPH). A wide array of complications due to UAE includes pulmonary embolism, uterine ischemia, necrosis, sepsis, and death. A 27 years old married woman (parity 1+2) presented with complaints of a mass protruding of the vagina with dirty brown vaginal discharge. Following UAE was done for postpartum hemorrhage (PPH) she had developed fever and burning micturition on which ultrasound was done to show an anteverted, enlarged, bulky uterus, with multiple endogenic foci, with endometrial canal and adjacent myometrium suggestive of infective pathology. In this case report complications of UAE for the management of PPH were discussed, however, research is required to comprehend the causes of uterine necrosis following uterine artery embolization and its management.

ObjectiveTo assess the impact of an evidence-informed protocol for management of placenta accreta spectrum (PAS).MethodsThis was a retrospective cohort study of patients who underwent cesarean hysterectomy (c-hyst) for suspected PAS from 2012 to 2022 at a single tertiary care center. Perioperative outcomes were compared pre- and post-implementation of a standardized Multidisciplinary Approach to the Placenta Service (MAPS) protocol, which incorporates evidence-informed perioperative interventions including preoperative imaging and group case review. Intraoperatively, the MAPS protocol includes placement of ureteral stents, possible placental mapping with ultrasound, and uterine artery embolization by interventional radiology. Patients suspected to have PAS on prenatal imaging who underwent c-hyst were included in the analysis. Primary outcomes were intraoperative complications and postoperative complications. Secondary outcomes were blood loss, need for ICU, and length of stay. Proportions were compared using Fisher's exact test, and continuous variables were compared used t-tests and Mood's Median test.ResultsThere were no differences in baseline demographics between the pre- (n = 38) and post-MAPS (n = 34) groups. The pre-MAPS group had more placenta previa (95% pre- vs. 74% post-MAPS, p = 0.013) and prior cesarean sections (2 prior pre- vs. 1 prior post-MAPS, p = 0.012). The post-MAPS group had more severe pathology (PAS Grade 3 8% pre- vs. 47% post-MAPS, p = 0.001). There were fewer intraoperative complications (39% pre- vs.3% post-MAPS, p 1l (95% pre- vs.65% post-MAPS, p = 0.001), ICU admissions (59% pre- vs.35% post-MAPS, p = 0.04) and shorter hospital stays (10 days pre- vs.7 days post-MAPS, p = 0.02) in the post-MAPS compared to pre-MAPS patients. Neonatal length of stay was 8 days longer in the post-MAPS group (9 days pre- vs. 17 days post-MAPS, p = 0.03). Subgroup analyses demonstrated that ureteral stent placement and uterine artery embolization (UAE) may be important steps to reduce complications and ICU admissions. When comparing just those who underwent UAE, patients in the post-MAPS group experienced fewer hemorrhages greater five liters (EBL >5l 43% pre- vs.4% post-MAPS, p = 0.007).ConclusionAn evidence-informed approach to management of PAS was associated with decreased complication rate, EBL >1l, ICU admission and length of hospitalization, particularly for patients with severe pathology.

Enhanced myometrial vascularity (EMV) is a rare disorder associated with various obstetrical and gynecological pathologies. We describe a unique case of interstitial ectopic pregnancy associated with EMV successfully managed with bilateral uterine artery embolization.

Abstract Background Caesarean scar pregnancy (CSP) is a special type of ectopic pregnancy with a high risk of massive haemorrhage. Few studies have focused on the efficacy of prophylactic abdominal aortic balloon occlusion as a minimally invasive method in caesarean section. This study aimed to evaluate the effectiveness and safety of prophylactic abdominal aortic balloon occlusion for patients with type III CSP. Methods This was a prospective cohort study. Patients with type III CSP in the First Affiliated Hospital of Zhengzhou University from January 2020 to June 2022 were enrolled. Eligible patients received prophylactic abdominal aortic balloon occlusion (defined as the AABO group) or uterine artery embolization (defined as the UAE group) before laparoscopic surgery. Clinical outcomes included intraoperative blood loss, body surface radiation dose, hospitalization expenses, and time to serum β-hCG normalization, and safety were also assessed. Results A total of 68 patients met the criteria for the study, of whom 34 patients were in the AABO group and 34 patients were in the UAE group. The median intraoperative blood loss in the AABO and UAE groups was 17.5 (interquartile ranges [IQR]: 10, 45) and 10 (IQR: 6.25, 20) mL, respectively (P = 0.264). The body surface radiation dose of the AABO group was much lower than that of the UAE group (5.22 ± 0.44 vs. 1441.85 ± 11.59 mGy, P

Uterine artery embolization (UAE) is a technique for management of various obstetrical and gynecological problems. Transfemoral approach (TFA) is preferred which can be unilateral or bilateral; however, unilateral puncture is preferred due to lesser chances of puncture-related complications as compared to bilateral puncture. UAE through unilateral TFA is possible with use of reverse loop catheters (Roberts uterine catheter [RUC] or Gandras catheter) to access ipsilateral uterine artery. Other way of cannulating the ipsilateral uterine artery is by maneuvering catheters to form Waltman's loop/Simmon's reverse loop. With advent of RUC, unilateral TFA became standard of care. In the recent past, RUC was retracted from Indian market and its nonavailability had mandated use of either bilateral TFA or use of catheters and techniques used in the past for unilateral TFA. Herein, we describe a technique of doing UAE by unilateral TFA using simple gentle curve catheter (Picard) by making a reverse curve loop.

Hysterectomy is the most common gynecologic procedure performed all over the world and various complications may appear depending on the surgical route. Delayed postoperative hemorrhage is a rare, life threatening complication. It requires timely management and recently the surgical reinterventions tend to be replaced by minimally invasive techniques. Transcatheter arterial embolization shows good results as a treatment strategy for massive vaginal bleeding post hysterectomy, when vaginal vault suturing fails to achieve hemostasis. We report a case of right uterine artery bleeding occurring 30 days after vaginal hysterectomy that was successfully treated by transcatheter arterial embolization.

Abstract Background Uterine arteriovenous malformation (UAVM) is a relatively rare but potentially life-threatening situations abnormal vascular connections between the uterine arterial and venous systems. Lack of recognized guidelines and clinic experience, there is a lot of clinic problems about diagnosis and treatment. By analyzing the clinical data of patients with pregnancy-related UAVM, we aim to confirm the safety of direct surgeries and the benefit of pretreatment (uterine artery embolization or medical therapy) before surgery, and to explore more optimal therapies for patients with pregnancy-related UAVM. Methods A total of 106 patients in Qilu Hospital of Shandong University from January 2011 to December 2021 diagnosed of pregnancy-related UAVM were involved in this study. Depending on whether preoperative intervention was performed, the patients were divided into direct surgery group and pretreatment group (uterine artery embolization or medical management). Clinical characteristics, operative related factors and prognosis were analyzed. Results The most common symptom of pregnancy-related UAVM was vaginal bleeding (82.5%), which could also be accompanied by abdominal pain. Pretreatments (uterine artery embolization or medical therapy) had no obvious benefit to the subsequent surgeries, but increased the hospital stay and hospital cost. Direct surgery group had satisfactory success rate and prognosis compared to pretreatment group. Conclusion For pregnancy-related UAVM, direct surgery has good effects and high safety with shorter hospital stays and less hospital cost. What is more, without uterine artery embolization and other medical therapy, patients could remain better fertility in future.

Abstract A 37-old III gravida II para with two previous cesarean sections (CS) presented in 7 + 3 weeks of pregnancy with cervical ectopic pregnancy (CEP). At 12th week of pregnancy, a cerclage was performed to avoid cervical distention by the expanding placenta. Due to missing experience in CEP management and to avoid emergency operation, we recommended CS in 30th week of pregnancy due to unspecific pain of the patient. Vaginal bleeding never occured. After transverse laparotomy, the urinary bladder was sharply dissected from the anterior uterine and cervical wall. The baby was delivered by transverse cervicotomy caudally of the placenta. The placenta was left in situ. The patient then got prophylactic embolization of the uterine arteries to prevent further severe hemorrhage. 48 h later, ultrasound showed a floating, avascular placenta within a poor echogenic fluid-filled cervical space as well as macrohematuria. After re-laparotomy and cervicotomy at the same day, the placenta was completely and easily evacuated. A bladder injury was recognized and closed. We performed a cervical internal os plasty by inverting the cervical lips and suturing their distal ends on the proximal cervical tissue, resulting in complete bleeding cessation. Although, the patient got 8 erythrocyte concentrates at all, she was always in a stable condition without hemorrhagic shock. This case demonstrates for the first time a live-birth with uterus-conserving management in CEP.

Background: This study aimed to evaluate the effectiveness of different treatments for cesarean scar pregnancy (CSP) and to identify key factors influencing treatment selection, in order to help standardize CSP management. Methods: We retrospectively analyzed data from 220 CSP patients at the Family Planning Department of the Women’s Hospital, School of Medicine, Zhejiang University, from January 2019 to December 2019, adhering to the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) guidelines. Treatment methods included dilation and curettage (D&C), curettage after uterine artery embolization (UAE+C), hysteroscopy plus curettage (H/S+C), H/S+C following UAE (UAE+H/S+C), and hysteroscopy combined with laparoscopic resection (L/S+H/S). We assessed treatment outcomes by evaluating the normalization of serum β-human chorionic gonadotropin (β-hCG) levels, disappearance of the isthmic mass, and the occurrence of complications. Results: No significant difference in treatment success rates was found among the groups (p > 0.05). Larger gestational sac diameter (GSD) and thinner myometrial thickness were significant factors in choosing uterine artery embolization (UAE) (p < 0.05), while thinner myometrial thickness alone was a predictor for selecting H/S+C (p < 0.05). The presence of a fetal heartbeat and the subtype of CSP also influenced the choice of UAE and surgical treatment (p < 0.05). Conclusions: This study highlights the need for personalized treatment plans for CSP, considering factors like GSD, myometrial thickness, heartbeat, and CSP subtype. Although no treatment method proved superior, the study identifies important considerations for treatment selection, emphasizing the importance of individualized care in CSP management. The use of STROBE guidelines ensured comprehensive reporting and analysis, offering valuable insights for CSP treatment.

Abstract Background The burden of uterine fibroids is substantial in sub-Saharan Africa (SSA), with up to 80% of black women harboring them in their lifetime. While uterine artery embolization (UAE) has emerged as an effective alternative to surgery to manage this condition, the procedure is not available to the vast majority of women living in SSA due to limited access to interventional radiology (IR) in the region. One of the few countries in SSA now offering UAE in a public hospital setting is Tanzania. This study aims to assess the safety and effectiveness of UAE in this new environment. Methods From June 2019 to July 2022, a single-center, retrospective cohort study was conducted at Tanzania’s first IR service on all patients who underwent UAE for the management of symptomatic fibroids or adenomyosis. Patients were selected for the procedure based on symptom severity, imaging findings, and medical management failure. Procedural technical success and adverse events were recorded for all UAEs. Self-reported symptom severity and volumetric response on imaging were compared between baseline and six-months post-procedure using paired sample t-tests. Results During the study period, 92.1% (n = 35/38) of patients underwent UAE for the management of symptomatic fibroids and 7.9% (n = 3/38) for adenomyosis. All (n = 38/38) were considered technically successful and one minor adverse event occurred (2.7%). Self-reported symptom-severity scores at six-months post-procedure decreased in all categories: abnormal uterine bleeding from 8.8 to 3.1 (-5.7), pain from 6.7 to 3.2 (-3.5), and bulk symptoms from 2.8 to 1 (-1.8) (p

Abstract Objective: To determine the efficacy of Uterine Artery Embolization in patients with bleeding acquired uterine arteriovenous malformations (AVMs). Methods: A prospective review of all patients who underwent Uterine Artery Embolization at our institution between July 2015 and April 2022 was performed. 225 patients were diagnosed with a uterine vascular malformation on doppler and corresponding MRI imaging. All patients underwent transcatheter embolization of the uterine arteries. Embolic agents in the 375 procedures included Histoacryl glue only (n = 326), polyvinyl alcohol (PVA) particles and Histoacryl glue (n = 29), PVA particles (n = 5), Gelfoam (n = 5), coils (n = 4), PVA particles and coils (n = 3), Histoacryl glue and Gelfoam (n = 2), and Histoacryl glue and coils (n = 1). Results: A total of 375 embolization procedures were performed in 225 patients. 90 patients required repeat embolization for recurrence of bleeding. The technical success rate of embolization was 100%. The clinical success rate was 92%: bleeding was controlled in 222 of 225 patients and three patients underwent a hysterectomy. 60 of the 225 patients had uneventful intrauterine pregnancies carried to term. The 210 patients who underwent successful embolization had no recurrence of bleeding at a median follow-up of 53 months (range, 5-122 months) after treatment. 15 patients were eventually lost to follow-up. One minor complication (0.4%) of non-flow-limiting dissection of the internal iliac artery occurred. Conclusion: Uterine Artery Embolization is a safe, effective, minimally invasive method to treat uterine AVMs with long-term efficacy, which can provide the preservation of fertility.

Uterine artery embolization is an established minimally invasive therapy for symptomatic fibroids. It has also been used for other diseases of the uterus, including adenomyosis, uterine arteriovenous malformation, ectopic pregnancy, abnormal invasive placenta, and postpartum hemorrhage. In this review, we provide an updated and comprehensive review of uterine artery embolization based on the evidence published. We review the indications, the role of MRI, technical aspects, and complications of the procedure. The issues with a future pregnancy, risk of infertility, and fetal radiation are discussed as well.

In this case series, we evaluated the efficacy and safety of uterine artery embolization (UAE) using N-butyl- 2-cyanoacrylate (NBCA)/glue for the treatment of uterine artery pseudoaneurysm (UAP). Here, we report 8 patients with uterine artery pseudoaneurysm, who underwent UAE using NBCA/glue. Angiograms and medical records were retrospectively analyzed to determine the technical success, clinical success, complications, average procedure time, the average duration of hospital stay after UAE. All patients were presented with secondary postpartum hemorrhage with hemodynamic instability. The technical and clinical success rates were 100%, respectively. The average procedure time was 21minutes and the average duration of hospital stay was 2.2 days. We did not encounter any major complications. Two patients following UAE were naturally conceived and delivered by repeat LSCS. UAE using NBCA/glue is a safe and effective treatment option for UAP in both hemodynamically stable and unstable patients.

Acquired uterine arteriovenous malformation is a rare condition, sometimes provoking abnormal life-threatening uterine hemorrhage. Here, we present the case of a 30-year-old healthy woman who developed heavy vaginal bleeding after dilatation and suctioning of the placenta 1 month after the delivery of a nonviable fetus. An ultrasound was performed which showed the appearance of a large exacerbation of a vessel with positive fetal sounds, normal cardiac movement, and normal morphological analysis. The patient was successfully treated with unilateral superselective embolization, distal to the ovarian supply, maintaining normal supply to the uterus and ovaries restoring normal menstruation, and showed complete resolution of the arteriovenous malformation.

ObjectiveThe assessment of the relative impacts of uterine artery embolization (UAE) treatment for female patients is a critical field that informs clinical decisions, yet there is a noticeable scarcity of high-quality, long-term comparative studies. This meta-analysis aimed to focus on the pregnancy rate and outcomes in female patients following UAE and to conduct subgroup analyses based on different patient populations or various control treatments.MethodsA systematic literature search was conducted on 2 August 2023 through the Web of Science, PubMed, Embase, and the Cochrane Library of Clinical Trials for all potential studies. Relative risks (RRs) with 95% confidence intervals (CIs) were applied to compare pregnancy rates and outcomes between the UAE group and the control group. Heterogeneity was evaluated statistically by using the chi-square-based Cochran’s Q test and Higgins I2 statistics, and 95% prediction interval (PI). Software R 4.3.1 and Stata 12.0 were used for meta-analysis. The trial sequential analysis (TSA) was performed with TSA v0.9.5.10 Beta software.ResultsA total of 15 eligible studies (11 cohort studies, 3 randomized controlled trials, and 1 non-randomized clinical trial) were included in this meta-analysis. The overall results revealed that UAE significantly decreased postoperative pregnancy rate [RR (95% CI): 0.721 (0.531–0.979), 95% PI: 0.248–2.097] and was associated with an increased risk of postoperative PPH [RR (95% CI): 3.182 (1.319–7.675), 95% PI: 0.474–22.089]. Analysis grouped by population indicated that UAE decreased the risk of preterm delivery [RR (95% CI): 0.326 (0.128–0.831), p = 0.019] and cesarean section [RR (95% CI): 0.693 (0.481–0.999), p = 0.050] and increased the risk of placenta previa [RR (95% CI): 8.739 (1.580–48.341), p = 0.013] in patients with UFs, CSP, and PPH, respectively. When compared with myomectomy, HIFU, and non-use of UAE, UAE treatment was associated with the reduced risks of preterm delivery [RR (95% CI): 0.296 (0.106–0.826)] and cesarean section [(95% CI): 0.693 (0.481–0.999), p = 0.050] and increased placenta previa risk [RR (95% CI): 10.682 (6.859–16.636)], respectively.ConclusionUAE treatment was associated with a lower postoperative pregnancy rate and increased risk of PPH. Subgroup analysis suggested that UAE was shown to decrease the risk of preterm delivery and cesarean section and increase placenta previa risk.Systematic review registration:https://www.crd.york.ac.uk/prospero/, Identifier CRD42023448257.

AbstractObjectives To investigate the menstruation recovery after two therapeutic regimens, high-intensity focused ultrasound (HIFU) or uterine artery embolization (UAE) combined with ultrasound-guided suction curettage, for premenopausal women with cesarean scar pregnancy (CSP).Materials and methods Seventy patients with CSP treated with HIFU followed by ultrasound-guided suction curettage and 63 patients with CSP treated with UAE followed by ultrasound-guided suction curettage in our hospital were retrospectively reviewed. The treatment parameters and the menstrual blood loss (MBL) volume at 6 months after the two therapeutic regimens were compared between the two groups.Results There was no significant difference in treatment results between the two groups. With regard to postoperative MBL volume, 5 out of 70 patients in the HIFU group and 22 out of 63 patients in UAE group exhibited a reduction in MBL, respectively. Multivariate logistic regression revealed that hypomenorrhea was more likely to occur in the UAE group than in the HIFU group (UAE group vs. HIFU group; OR 11.328, 95% CI 3.158–55.871; p

AbstractObjective To compare the efficacy and safety of different treatment options for cervical pregnancy (CP).Materials and methods A total of 74 patients diagnosed with CP at Hunan Provincial Maternal and Child Health Care Hospital between January 2016 and September 2022 were retrospectively analyzed. Among them, 31 were treated with uterine artery embolization (UAE) followed by hysteroscopic curettage, 34 were treated with hysteroscopic curettage alone, and nine were treated with high-intensity focused ultrasound (HIFU) followed by hysteroscopic curettage. Medical records and pregnancy outcomes were analyzed.Results There were no significant differences in age, gravidity, parity, abortion, or preoperative hemoglobin levels among the patients in the three groups; however, significant differences in gestational age, gestational sac diameter, preoperative β-hCG, and presence of cardiac pulsation were observed (p

Purpose This study aimed to evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for bleeding due to uterine body cancer. Materials and Methods In this retrospective study, six patients with varying types of uterine body cancer who underwent TAE for bleeding control were investigated. Angiographic findings, cross-sectional images, TAE details, and clinical outcomes were studied. Technical and clinical success rates were calculated. Results The identified patients had endometrioid adenocarcinoma, sarcoma, and gestational trophoblastic neoplasia, and most were patients with advanced-stage cancer. In four patients, tumor bleeding presented as vaginal bleeding. Technical success was achieved in all seven TAE procedures in six patients. Two patients with recurrent masses who had undergone hysterectomy presented with hematochezia, and TAE was able to provide technical success in these patients as well. The clinical success rate was 50%, indicating bleeding control for > 1 week. Rebleeding was directly associated with death in one patient. On the following day, mild fever was observed in one patient. Conclusion TAE can be considered an effective and safe method of bleeding control for uterine body cancer, especially during critical periods throughout the disease course of patients with inoperable, advanced-stage cancer.

Abstract Background The aim of this systematic review and meta-analysis was to introduce the relatively novel method of ultrasound-guided local lauromacrogol injection (USG-LLI) followed by dilatation and curettage for caesarean scar pregnancy (CSP) and to investigate the clinical safety and efficacy between uterine artery embolization (UAE) and USG-LLI in the treatment of CSP. Methods The relevant literature and articles about USG-LLI, UAE and CSP published in eight electronic databases were searched to extract the primary outcomes for the selected articles. Review Manager Software(RevMan) V.5.2 was used for quantitative data synthesis and data analysis. Forest plots, sensitivity analysis and bias analysis were also performed on the included articles. Results Of 10 studies included in our search, 623 patients were in the USG-LLI group and 627 patients were in the UAE groups. There were no significant differences between the two groups in terms of success rate, blood loss and time to human chorionic gonadotropin (hCG) normalization. However, USG-LLI group patients than UAE group patients had a shorter duration of hospital stay (mean difference [MD] = -1.97; 95% confidence intervals [CI] -2.63 to -1.31; P

Background and Objectives: Cesarean scar pregnancy (CSP) represents a type of ectopic pregnancy in which the embryo implants inside the scar of a previous cesarean section. This condition can lead to maternal morbidity and mortality. The best therapeutic approach in terms of clinical effectiveness and patient safety for CSP has not been described yet, although different therapeutic strategies are currently available. The purpose of the present study was to analyze the success rate of two different treatments in a single institution. Materials and Methods: A retrospective study was performed among patients diagnosed with CSP at the Gynecology and Obstetrics Department of the “Cannizzaro” Hospital in Catania (University of Enna—Italy) from January 2016 to December 2022. The diagnosis was made by 2D/3D transvaginal ultrasound, following Timor-Tritsch criteria. Two treatment strategies were performed: local and systemic methotrexate (MTX) injection and uterine artery embolization (UAE) with subsequent dilatation and curettage (D&C). All treated women underwent subsequent clinical and sonographic follow-up. Complete recovery was defined as the reduction of β-HCG values until it was undetectable and the disappearance of the mass in the uterine scar on ultrasound. Results: Nineteen patients were included; nine were in the MTX group and ten were in the UAE + D&C group. No significant differences were found between the two groups in terms of clinical parameters. Treatment was successful in 4 of 10 (44%) patients in the MTX group and 10 of 10 (100%) in the UAE + D&C group (p = 0.01); the length of hospital stay was significantly shorter in the latter group (p < 0.0001). Conclusions: In our experience, administration of MTX is not recommended as the primary treatment or pre-treatment. Dilatation and curettage after uterine artery embolization are better than methotrexate injection for the treatment of cesarean scar pregnancy in a single-institution series in terms of complete recovery and length of hospital stay.

Uterine artery embolization (UAE) is an effective minimally invasive alternative to surgery for the treatment of symptomatic uterine fibroids. Uterine rupture is an obstetrical emergency that requires early diagnosis and prompt management to improve perinatal and maternal outcomes.A 33-year-old woman at 37 weeks of gestation who had had previous two uncomplicated vaginal deliveries at term presented with abdominal pain and rupture of membranes. The patient had undergone UAE for the management of a large anterior wall uterine fibroid three years prior to conception. Vaginal examination revealed cord prolapse and ultrasound showed negative fetal heart. Intrauterine fetal demise with cord prolapse was diagnosed. After admission the patient developed vaginal bleeding and features of hypovolemic shock. Urgent laparotomy revealed a ruptured uterus with a large hemoperitoneum and dead fetus in the abdominal cavity.Obstetricians should be attentive to the possibility of a spontaneous uterine rupture in pregnant women who have previously undergone UAE for the management of a uterine fibroid.

This report documents the case of a patient with a previously diagnosed partial molar pregnancy evacuated by dilation and suction curettage with appropriately declining post-operative levels of beta-human chorionic gonadotropin (beta-hCG), who, one month later, underwent uterine artery embolization in the setting of acute bleeding and imaging concerning for arteriovenous malformation. After embolization, beta-hCG levels increased, prompting concern for gestational trophoblastic neoplasia and referral to gynecologic oncology. With further workup, the elevation was found to be transient and benign – a phenomenon not previously described.

The current standard treatment for placenta accreta is a hysterectomy, which carries a significant risk of hemorrhage. Although prophylactic uterine artery embolization (UAE) is established as an effective means of minimizing perioperative bleeding, there are few reports of its use early in pregnancy with invasive placenta.A 45-year-old woman, gravida 6, para 1, at 11 weeks of gestation presented with heavy, painless uterine bleeding and was diagnosed with a spontaneous abortion complicated by cervical pregnancy and placenta accreta. The patient underwent bilateral UAE followed by gravid hysterectomy.This case report encourages prophylactic UAE prior to abdominal hysterectomy in patients with early gestational cervical pregnancy and placenta accreta to minimize blood loss during surgery.

Background. Uterine myoma is the most common benign tumor of the pelvic organs in women. One of the effective therapies for myomas is uterine artery embolization (UAE), which can be associated with unintended ovarian embolization. However, there is no certainty about the effect of unintended ovarian embolization on fertility and ovarian function since no precise evidence-based ways of identifying unintended embolization have been described. Aim. To develop a highly accurate method for identifying unintended ovarian embolization during UAE. Materials and methods. A series of clinical cases of the utilization of combined embolization material based on the paramagnetic contrast agent gadoteridol and saturable HepaSphere microspheres are presented. Results. On admission, patients underwent magnetic resonance imaging (MRI) of the pelvic organs with contrast enhancement. After UAE with this combined embolization material, another pelvic MRI without contrast enhancement was performed on the in-hospital day 2. In the first clinical case, no hyperintensive zones were detected in the ovarian stroma. However, in the second case, a previously undetected hyperintensive signal up to 6 mm in diameter was seen in the stroma of the left ovary by repeat MRI. Conclusion. Using this combined material during UAE significantly increases the accuracy of possible unintended ovarian embolization detection as soon as in the early postoperative period.

Introduction: Gestational trophoblastic neoplasia (GTN) is a rare disorder, especially in nulliparous women. This study introduced a patient with GTN who underwent successful and uncomplicated treatment of uterine artery embolization and chemotherapy. Case presentation: The patient was a 29-year-old woman with a history of two pregnancies who referred to Amiralmomeni hospital of Semnan with complaint of severe vaginal bleeding. On ultrasonography, the hypo-echo mass with cystic changes was seen in favor of GTN. Due to the young age of the patient and to preserve the uterus and re-pregnancy, treatment was performed with uterine artery embolization and then chemotherapy, and treatment was successful. Conclusion: In patients with GTN, uterine artery embolization along with chemotherapy can be considered an effective treatment with minimal complications, especially in young nulliparous women who are interested in preserving the uterus.

Abstract Background Cesarean scar pregnancy (CSP) treated with either high-intensity focused ultrasound ablation (HIFU-a) or uterine artery embolization (UAE) combined with ultrasound-guided dilation and curettage (USg-D&C) was effective. However, there is insufficient comparative research evidence on clinical efficacy and subsequent pregnancy outcomes after previous CSP treatment. This study aims to investigate the efficacy, safety, and subsequent pregnancy outcomes of HIFU-a compared to UAE before USg-D&C for the treatment of CSP. Methods Between January 2016 and July 2020, a total of 272 patients received the pretreatment with HIFU-a or UAE(HIFU-a group: n = 118; UAE group: n = 154). The clinical characteristics, treatment success rate, postoperative pregnancy rate and outcome of the two groups were compared and analyzed. Results The demographic characteristics of the two groups were similar. After pretreatment, the adverse events rate of HIFU-a group was lower than that of UAE group (10.40% (16/154) vs. 40.70% (48/118), P = 0.00). All patients received the USg-D&C. The HIFU-a group was of less intraoperative blood loss (10.00 (5.00–20.00) vs. 12.50 (5.00–30.00) ml, P = 0.03). There was no statistically significant difference between the two groups in success rates. However, the HIFU-a group was of a shorter duration of postoperative vaginal bleeding (12.00 (9.00–13.00) vs. 14.00 (12.00–15.00) days, P = 0.00). There was no significant difference between the two groups in terms of subsequent pregnancy rates (P = 0.317). However, the recurrent CSP (rCSP) rate in the HIFU-a group was lower than that in the UAE group (7.70% (6/78) vs. 19.70%(13/66), P = 0.03). Conclusions CSP treated with either HIFU-a or UAE combined with USg-D&C was safe and effective. Although no significant difference was found in the subsequent pregnancy outcomes of the two groups, the rCSP was more common in the UAE group. So, we recommend HIFU-a combined with USg-D&C treatment modality.

Introduction: Placenta accreta is a general term, when part of the placenta or the entire placenta invades and is inseparable from the uterine wall. The incidence is considerably higher in women with both a previous caesarean delivery and placenta praevia, occurring in around 1 in every 20 such women. Resorption of the retained, poorly perfused placenta can be augmented by concurrent treatment with methotrexate when fertility is desired. In cases where operative measures are required, placement of Internal Iliac artery (IIA) balloons preoperatively and their inflation intraoperatively, reduces maternal morbidity and mortality. Materials and Methodology: We present a case series of 14 patients with placenta accreta diagnosed preoperatively, 7 of whom had IIA balloons placed before undergoing Caesarean section and 7 did not have such an intervention. The maternal and foetal morbidity and mortality were studied, including the need for blood and blood product transfusions. Results: Internal Iliac Balloon placements did not change the requirement for blood and blood product transfudion in both groups. The group who had IIA balloon placed preoperatively had better maternal and fetal outcome as compared to the group who had no such intervention.

Background: Incidental identification of peritoneal nodules during laparoscopy may present a diagnostic dilemma. The differential diagnosis includes a variety of benign and malignant entities such as peritoneal carcinomatosis. Case: A 44-year-old G2P2 woman presented with recurrent menorrhagia and pelvic pain was found to have large uterine fibroids on imaging studies. Bilateral uterine artery embolization was performed with complete devascularization of the fibroid. Seven years later, she presented with similar symptoms. Imaging studies demonstrated a vascular uterine lesion. A total laparoscopic hysterectomy with bilateral salpingectomy was performed with no complications. During surgery, vesicular peritoneal implants were incidentally identified posterior to the uterus between the uterosacral ligaments. Biopsy and pathologic analysis of these nodules confirmed that they contained foreign material consistent with embolization beads. Pathologic analysis of the uterus demonstrated an intramural uterine fibroid, and presence of embolization beads in cervix, myometrium and bilateral peritubal regions. Conclusion: Non-target peritoneal implantation of embolic beads after uterine artery embolization is a rare entity that can result in vesicular appearing nodules.

Objective To explore the differences of different clinical indicators between patients with severe and non-severe intrauterine adhesions （IUA）. Methods Clinical data of 118 patients with IUA diagnosed by hysteroscopy were analyzed retrospectively. According to the AFS scoring standard of IUA, all patients were divided into the severe IUA group （severe group） and mild-moderate IUA group （non-severe group）, and the differences of different clinical indicators between two groups were analyzed. Results Compared with the patients in the non-severe group, the patients in the severe group had more pregnancies, more than two times of uterine curettage, and more times of hysteroscopic resection （all P < 0.05）. There were statistically significant differences between the severe and non-severe groups after induced abortion, hysteroscopic resection, and uterine artery embolization combined with curettage （all P < 0.05）. Among the patients undergoing different times of uterine cavity operations, the difference between the severe and non-severe groups was statistically significant. Compared with the 1-time and 2-time uterine cavity operation groups, the proportion of severe group （85%） in the ≥3-time uterine cavity operation was significantly increased （both P < 0.05）. In the severe group, the proportion of abnormal uterine cavity （heterogenous echoes, continuous interruption, unclear display or adhesion） revealed by transvaginal color Doppler ultrasound was significantly higher than that in the non-severe group （P < 0.05）. Conclusions Induced abortion, hysteroscopic electrosurgery and uterine curettage after uterine artery embolization can increase the risk of IUA. Transvaginal color Doppler ultrasound has good diagnostic value for severe IUA.

Abstract Background Uterine fibroid embolisation (UFE) is an established treatment method for symptomatic uterine myomas. This study evaluates the efficacy of UFE using objective magnetic resonance imaging (MRI) data for size and perfusion analysis as well as patient questionnaires assessing fibroid-related symptoms. Method Patients underwent MR-Angiography before UFE and 4 days, 6 and 12 months after the procedure. The images were evaluated using dedicated software. Patient questionnaires were completed before UFE and at 12 months follow-up, focussing on the embolization procedure and symptoms associated with uterine fibroids. Statistical analysis of the questionnaires was performed using paired sample t-test and Wilcoxon signed rank test, while Kruskal–Wallis test and Friedman test were applied for MRI-analysis. Results Eleven women were included. There was a significant reduction in fibroid-related symptoms. The volume reduction after 12 months was significant in both, uterus and myomas, after an initial increase in uterine volume at the first post-interventional MRI. The perfusion analysis showed that blood flow to the fibroids could be significantly reduced up to 12 months after UFE while uterine tissue was not affected. Conclusion This study shows that uterine fibroid embolisation induces a significant long-term decrease in myoma size and perfusion while healthy uterine tissue remains unaffected. Fibroid-related symptoms are reduced for the sake of improved quality of life.

Objective This study was aimed at comparing the outcomes of high-intensity focused ultrasound (HIFU) with those of uterine artery embolization (UAE) and traditional surgeries for treating symptomatic uterine fibroids. Materials and methods We searched the following databases from their beginning to 5 November 2021: PubMed, Medline, Embase and Cochrane Library. Results Overall, 21 studies were included in this meta-analysis. The results revealed that HIFU had a higher re-intervention rate than UAE (relative risk [RR] = 4.06, 95% confidence interval [CI]: 2.47–6.69) and offered no significant advantages in reducing the symptom severity score (SSS) (mean difference [MD] = 17.01, 95% CI: 10.25–23.77) and improving the health-related quality of life (HRQoL) score (MD= −18.32, 95% CI: −24.87 to −11.78) in the treatment of symptomatic uterine fibroids. However, compared with UAE, HIFU may be associated with a higher pregnancy rate (RR = 17.44, 95% CI: 2.40–126.50) and may have a significant advantage in shortening pregnancy interval and preserving ovarian function. Moreover, upon comparing HIFU with traditional surgical treatments, the HIFU group showed significantly improved HRQoL score (MD = 2.25, 95% CI: 1.15–3.35), but the re-intervention rate (RR = 1.65, 95% CI: 0.59–4.57), pregnancy rate (RR = 1.01, 95% CI: 0.90–1.13), SSS and ovarian function did not significantly differ between the two groups. Conclusions Although HIFU has relatively high re-intervention rate, it may offer a higher pregnancy rate and shorter pregnancy interval with little influence on ovarian function, thus making it an attractive option for treating symptomatic fibroids in young women who wish to plan a pregnancy in the future.

Objective To evaluate the efficacy, feasibility and acceptability of microwave ablation (MWA) compared to uterine artery embolization (UAE) as treatment for uterine fibroids. Method A randomized controlled superiority trial, including premenopausal women 30–55 years, with symptomatic uterine fibroids without any single fibroid exceeding mean diameter of eight centimeters. Patients were randomized to receive microwave ablation, performed abdominally or vaginally, or to uterine artery embolization. The primary outcome was volume difference of the three largest fibroids at 6 months post treatment evaluated by magnetic resonance imaging (MRI) by a blinded radiologist analyzed by Mann–Whitney U-test. Secondary outcomes included symptom severity score (SSS), health related quality of life (HR-QoL), amount of menstrual bleeding, postoperative pain, length of hospitalization, need for additional treatment, adverse events and if patients would recommend the treatment to a friend. Results Patients were recruited from 30 January 2017 to 12 September 2019, with a total of 17 patients treated in each group from May 2017 to December 2019. Superiority of MWA could not be established. The volume reduction was 41.8% (Interquartile range, IQR, 14–63) in the MWA group compared to 62.2% (IQR 34.9–80.1) in the UAE group (p = 0.29). Effects on symptoms, HR-QoL and acceptability did not differ between groups. Days of hospitalization and sick leave were significantly fewer in the MWA group (p

Abstract Background A subsequent pregnancy after uterine artery embolization (UAE) raises several concerns, one of which is placenta accreta spectrum (PAS). Placenta previa is the strongest risk factor for PAS, which is most likely to occur in the lower uterine segment. PAS without placenta previa (i.e., uterine body PAS) is considered relatively rare. Case presentation A 35-year-old woman, gravida 2 para 1, had undergone UAE for postpartum hemorrhage due to uterine atony after vaginal delivery in her previous pregnancy. She developed placenta previa during her subsequent pregnancy and was therefore evaluated for PAS in the lower uterine segment. On the basis of examination findings, we considered PAS to be unlikely. During cesarean section, we found that the placenta was not detached from the uterine body, and the patient was determined to have uterine body PAS. Ultimately, a hysterectomy was performed. Conclusions PAS can occur in a subsequent pregnancy after UAE. When a subsequent pregnancy after UAE is accompanied by placenta previa, it is important to maintain a high index of suspicion of uterine body PAS without being misled by the presence of placenta previa.

Endometriosis-related symptoms are believed to be alleviated during pregnancy. However, pregnancy complications, such as pseudoaneurysm of the uterine artery, rupture of ovarian or uterine vessels, and intraabdominal bleeding from decidualized deep infiltrating endometriosis (DIE) lesion have been rarely reported. Owing to the potential risk of rupture and resultant life-threatening complications, proper diagnosis and close monitoring of decidualized endometriotic lesion are very important despite its low relative risk. Till date, massive vaginal bleeding from decidualized rectovaginal DIE during pregnancy has not been in English literatures. Here, we present the first case of spontaneous massive vaginal bleeding due to decidualized rectovaginal DIE that occurred in the late third trimester of pregnancy.

Introduction: Uterine fibroids are the most common benign tumors of the uterus. Most often they are asymptomatic, but in their course there may be ailments such as: abnormal bleeding, anaemia, pain, constipation, problems with urination. These tumors are also one of the many causes of infertility. They are most often detected during a standard ultrasound examination. Pharmacological, minimally invasive and surgical treatment is currently available. Aim: The aim of our study was to review scientific articles in order to demonstrate whether the treatment of uterine fibroids with uterine artery embolization has an impact on fertility and pregnancy outcomes. Materials and methods: Review of the latest PubMed literature, Google Scholar in the period 2017 - 2023 and evaluation of available randomized controlled trials using uterine artery embolization in terms of fertility preservation by assessing ovarian reserve, number of pregnancies, miscarriages and perinatal complications. Conclusions: Uterine artery embolization is a safe and effective method in reducing symptoms associated with uterine fibroids. This procedure shortens hospitalization and recovery time compared to myomectomy or hysterectomy. Unfortunately, for women who want children, this method is not recommended due to the risk of reduced ovarian reserve and miscarriage, premature birth, placental abnormality, and severe postpartum hemorrhage.

Uterine fibroids (UF) is an extremely common benign tumor of the female reproductive system. This pathology is often associated with symptoms that significantly impair the quality of life of a woman and her working capacity, and can also affect the ability to conceive and gestation. Today, we have in the arsenal of operational, drug and minimally invasive methods of UF treatment. One of the most researched and at the same time rather controversial methods of UF treatment is uterine artery embolization (UAE). Literary sources were reviewed using the MEDLINE, PubMed and Web of Science databases for the period 2011–2021. The data related to the history of the technique development, its implementation, indications and contraindications for UAE, its effect on the UF symptoms and on fertility were systematized and presented in this review. UAE as an independent method for the treatment of benign uterine tumors has 20 years of experience in the world and in Ukraine. The indications for UAE are symptomatic UF: profuse and/or prolonged menstruation, dysmenorrhea, compression of the pelvic organs, dyspareunia, frequent urination or urinary retention. Absolute contraindications for UAE are genital tract infections, pregnancy, doubts about the diagnosis, as well as contraindications to the use of X-ray contrast agents. The effectiveness of UAE is assessed by the manifestations of UF symptoms and by the degree of fibroids size reduction. The average node reduction in the diameter is 2.2 cm. The clinical efficacy index is 81–96, 70–100 and 46–100% respectively in the treatment of abnormal uterine bleeding, pelvic pain and symptoms of compression of adjacent organs. There is a decrease in the node volume by 25–60% within 3–6 months. Conclusions. UAE today is an effective and safe minimally invasive operation, which is a worthy alternative to hysterectomy and expands the possibilities of organ-preserving technologies if there is UF.

Uterine artery embolization (UAE) is one of the primary therapies to treat symptomatic uterine fibroids. Even if the patient underwent internal iliac artery ligation during a massive pelvic hemorrhage or peripartum bleeding previously, UAE can be done through the collaterals for any other reasons. We report a 44-year-old woman who underwent UAE for symptomatic multiple uterine fibroids after internal iliac artery ligation with collaterals originating from the left external iliac artery. We briefly present the case's details and review collaterals pathways after left internal iliac artery ligation that might be encountered during UAE.

Abstract Background Acute puerperal uterine inversion is rare but may cause massive postpartum blood loss due to uterine atony. Therefore, these patients must be diagnosed, and uterine replacement must be performed as soon as possible. However, in some cases, active bleeding due to uterine atony becomes uncontrollable, even though the uterine inversion itself is treated. In these cases, additional treatments, including surgical procedures, are needed. Case presentation A 41-year-old Japanese woman, gravida 1, para 0, was hospitalized for labor induction at 40 weeks and 3 days of gestational age. She had a vacuum-assisted delivery after 3 days of oxytocin administration, but acute uterine inversion occurred. Although replacement of the inverted uterus was successful by manual repositioning and Bakri balloon tamponade insertion, massive postpartum hemorrhage caused by uterine atony became uncontrollable. In this situation, since disseminated intravascular coagulation had developed, we used uterine artery embolization to stop the bleeding. After detecting the pseudo-aneurysmal sac and tortuous vessels of the right uterine artery, transcatheter right-sided uterine artery embolization was performed. Thirteen days after uterine artery embolization, she was discharged with no complications. Conclusions In cases of disseminated intravascular coagulation caused by massive postpartum bleeding, uterine artery embolization may often be selected. In our case, since we performed angiography to detect the main bleeding site, the hemorrhage could be stopped with unilateral uterine artery embolization alone, without hysterectomy.

Acute puerperal uterine inversion is a rare postpartum obstetric complication; however, without rapid diagnosis and appropriate management, it is life-threatening. Substantial bleeding hinders the verification of a partially inverted uterus, possibly delaying the treatment. Herein, we present the report of a 32-year-old female presenting with massive postpartum bleeding managed by uterine artery embolization. The peculiar course of the uterine artery bowing inferiorly along the inverted fundus during embolization could uncover the uterine inversion, which was not diagnosed by physical examination and CT. In conclusion, uterine artery embolization is not only an effective therapeutic strategy for postpartum hemorrhage but also a valuable tool for diagnosing uterine inversion.
