To determine relationships between prophylactic inferior vena cava filter (IVCF) insertion and pulmonary embolism (PE), deep venous thrombosis (DVT), and in-hospital mortality outcomes in patients with severe traumatic pelvic/lower extremity, intracranial, and spinal cord injuries.Adult patients with severe traumatic pelvic/lower extremity, intracranial, and spinal cord injuries admitted to level I-IV trauma centers were selected from the National Trauma Data Bank (NTDB). IVCFs that were inserted both ≤48 h after admission and before a lower extremity venous ultrasound were defined as prophylactic. Associations between prophylactic IVCF insertion and PE, DVT, and overall mortality outcomes during admission were estimated using logistic regression models after propensity score matching. Additionally, factors predictive of prophylactic IVCF insertion were estimated using multivariate logistic regression.Of 462,838 patients, 11,938 (2.6%) underwent prophylactic IVCF insertion. Prophylactic IVCF utilization decreased over time (6.3% in 2008 to 1.8% in 2015). Factors associated with prophylactic IVCF placement were injury pattern, trauma center level/region, Injury Severity Score, and race. Prophylactic IVCF placement was positively associated with PE (Odds Ratio (OR): 5.25, p 0.01) and DVT (OR: 5.55, p 0.01), but negatively associated with in-hospital mortality compared to the propensity score-matched control group (OR: 0.46, p 0.01).Prophylactic IVCF insertion in adult patients with severe pelvic/lower extremity fractures, intracranial injuries, and spinal cord injuries was negatively associated with in-hospital mortality, but positively associated with VTE. Further research evaluating the use of prophylactic IVCF placement in trauma patients with these specific severe injury types may be warranted.

To compare the clinical outcomes and trends of arterial embolization (AE) versus laparotomy which are used in the management of pelvic trauma.Adult patients with pelvic injuries were identified using the National Trauma Data Bank (NTDB) from 2007 to 2015. Patients with non-pelvic life-threatening injuries were excluded. Patients were grouped in operatively managed pelvic ring injuries, laparotomy ± fixation, AE ± fixation, and laparotomy and AE ± fixation. Using a linear mixed regression and logistic regression models, hospital length of stay (LOS), ICU days, ventilator days, and mortality for different therapies were compared. A propensity score weighting method was used to further eliminate treatment selection bias in the study sample and compare the outcomes between AE and laparotomy.Of 7473 pelvic trauma patients, 1226 (16.4%) patients were only operatively managed. 3730 patients (49.9%) underwent laparotomy, 2136 underwent AE (28.6%), and 381 (5.1%) patients underwent both laparotomy and AE. The year of injury, patient age, gender, race, severity of injury and presence of shock were found to be predictors of receipt of different therapies (P 0.001 for all). When correcting for these confounding factors, the mortality rate was lower in the AE group compared to the laparotomy group 6.6% vs. 20.6% (P 0.001). Additionally, LOS and ICU days were shorter for the AE group than the laparotomy group (P 0.001).AE in patients with pelvic injuries is associated with lower mortality, as well as shorter LOS and ICU stays compared to laparotomy.

Female physicians in academic medicine have faced barriers that potentially affect representation in different fields and delay promotion. Little is known about gender representation differences in United States academic radiology departments, particularly within the most pursued subspecialties.To determine whether gender differences exist in United States academic radiology departments across seven subspecialties with respect to academic ranks, departmental leadership positions, experience, and scholarly metrics.In this cross-sectional study from November 2018 to June 2020, a database of United States academic radiologists at 129 academic departments in seven subspecialties was created. Each radiologist's academic rank, departmental leadership position (executive-level - Chair, Director, Chief, and Department or Division Head vs vice-level - vice, assistant, or associate positions of executive level), self-identified gender, years in practice, and measures of scholarly productivity (number of publications, citations, and h-index) were compiled from institutional websites, Doximity, LinkedIn, Scopus, and official NPI profiles. The primary outcome, gender composition differences in these cohorts, was analyzed using ChiOverall, 5086 academic radiologists (34.7% women) with a median 14 years of practice (YOP) were identified and indexed. There were 919 full professors (26.1% women, p0.01) and 1055 executive-level leadership faculty (30.6% women, p0.01). Within all subspecialties except breast imaging, women were in the minority (35.4% abdominal, 79.1% breast, 12.1% interventional, 27.5% musculoskeletal, 22.8% neuroradiology, 45.1% pediatric, and 19.5% nuclear; p0.01). Relative to subspecialty gender composition, women full professors were underrepresented in abdominal, pediatric, and nuclear radiology (p0.05) and women in any executive-level leadership were underrepresented in abdominal and nuclear radiology (p0.05). However, after adjusting for h-index and YOP, gender did not influence rates of professorship or executive leadership. The strongest single predictors for professorship or executive leadership were h-index and YOP.Women academic radiologists in the United States are underrepresented among senior faculty members despite having similar levels of experience as men. Gender disparities regarding the expected number of women senior faculty members relative to individual subspecialty gender composition were more pronounced in abdominal and nuclear radiology, and less pronounced in breast and neuroradiology. Overall, h-index and YOP were the strongest predictors for full-professorship and executive leadership among faculty.● Though women comprise 34.7% of all academic radiologists, women are underrepresented among senior faculty members (26.1% of full professors and 30.6% of executive leadership) ● Women in junior faculty positions had higher median years of practice than their male counterparts (10 vs 8 for assistant professors, 21 vs 13 for vice leadership) ● Years of practice and h-index were the strongest predictors for full professorship and executive leadership.

Traditionally, hospital medicine services have been dominated by the physician and hospital team, with significant barriers to patient- and family-centered care. This article offers principles and associated strategies to reduce those barriers and guide implementation of systemically informed, collaborative, and culturally responsive patient- and family-centered care provided by hospitalist care teams, especially regarding collaborative decision-making for treatment and discharge planning. Such an approach is associated with reduced lengths of stay and hospital costs and lowered rates of medical errors and mortality. It also is linked to improved patient and family cooperation and adherence; enhanced quality of care and clinical outcomes; and increased levels of satisfaction among health care professionals, patients, and families. Such care uses resources wisely and is effective and ethical. We hope articulating and illustrating these principles and strategies will facilitate efforts to shift the health care culture from being physician-centered to truly team-, patient-, and family-centered.

Purpose To determine predictors of survival after transarterial radioembolization of hepatic metastases from breast cancer. Materials and Methods Twenty-four patients with chemotherapy-refractory hepatic metastases from breast cancer who underwent radioembolization from 2013 to 2018 were evaluated based on various demographic and clinical factors before and after treatment. Overall survival (OS) was estimated by Kaplan–Meier method. Log-rank analysis was performed to determine predictors of prolonged OS from the time of first radioembolization and first hepatic metastasis diagnosis. Results Median OS times were 35.4 and 48.6 months from first radioembolization and time of hepatic metastasis diagnosis, respectively. Radioembolization within 6 months of hepatic metastasis diagnosis was a positive predictor of survival from first radioembolization, with median OS of 38.9 months vs 22.1 months for others (P = .033). Estrogen receptor (ER)–positive status predicted prolonged survival (38.6 months for ER+ vs 5.4 months for ER−; P = .005). The presence of abdominal pain predicted poor median OS: 12.8 months vs 38.6 months for others (P Conclusions In patients with metastatic breast cancer, radioembolization within 6 months of hepatic metastasis diagnosis and ER+ status appear to be positive predictors of prolonged survival. Conversely, baseline abdominal pain, baseline ascites, and treatment-related grade ≥ 2 toxicity at 3 months after treatment appear to be negative predictors of OS.

To investigate timing of Yttrium-90 radioembolization (Y90) during treatment course, genomics, and other clinical factors as predictors of overall survival (OS) in colorectal liver metastasis (CRLM) that have progressed on at least one line of chemotherapy. This was a retrospective study from 2013 to 2018 of patients with CRLM and genomic analysis prior to Y90 at a multihospital tertiary referral center. OS from liver metastasis diagnosis and predictors of OS were analyzed using Kaplan–Meier estimation with log-rank and Cox regression analyses. Overall, 58 patients with CRLM who progressed on at least one line of chemotherapy who had genomic analysis prior to Y90 were identified. Median OS after hepatic metastasis was 29.9 months. Of these, 16 (28%) patients received Y90 after failure of the first-line systemic chemotherapy. There was significantly prolonged OS in patients receiving Y90 immediately following failure of the first-line chemotherapy folinic acid, fluorouracil, oxaliplatin ((FOLFOX) ± bevacizumab) versus following multiple lines of chemotherapy (median OS of 46.3 vs. 26.6 months, P = 0.005). The presence of genetic mutation in tumor, MAPK pathway wild type, left-sided primary tumor, low MELD score, and non-diffuse unilobar disease were also found to be predictors prolonged survival on log-rank analysis (P’s

Social determinants of health, including race and insurance status, contribute to patient outcomes. In academic health systems, care is provided by a mix of trainees and faculty members. The optimal staffing ratio of trainees to faculty members (T/F) in radiology is unknown but may be related to the complexity of patients requiring care. Hospital characteristics, patient demographics, and radiology report findings may serve as markers of risk for poor outcomes because of patient complexity.Descriptive characteristics of each hospital in an urban five-hospital academic health system, including payer distribution and race, were collected. Radiology department T/F ratios were calculated. A natural language processing model was used to classify multimodal report findings into nonacute, acute, and critical, with report acuity calculated as the fraction of acute and critical findings. Patient race, payer type, T/F ratio, and report acuity score for hospital 1, a safety net hospital, were compared with these factors for hospitals 2 to 5.The fraction of patients at hospital 1 who are Black (79%) and have Medicaid insurance (28%) is significantly higher than at hospitals 2 to 5 (P.0001), with the exception of hospital 3 (80.1% black). The T/F ratio of 1.37 at hospital 1 as well as its report acuity (28.9%) were significantly higher (P.0001 for both).T/F ratio and report acuity are highest at hospital 1, which serves the most at-risk patient population. This suggests a potential overreliance on trainees at a site whose patients may require the greatest expertise to optimize care.

Rationale and Objectives Requests for gastrostomy tube placement in patients on aspirin (ASA) 325 mg are common, particularly in patients following reconstructive surgery for head and neck cancer, but periprocedural guidelines and recommendations regarding management of high dose aspirin are inconsistent. The purpose of this study was to assess the bleeding risk of percutaneous gastrostomy tube placement in patients on ASA 325 mg. Materials and Methods This retrospective study of 213 patients who underwent image-guided “push” percutaneous gastrostomy tube placement compared rates of significant bleeding and other secondary outcomes (including all-cause mortality within 30 days, procedure-related mortality, bowel perforation, abdominal abscess, peritonitis, aspiration pneumonia, intraprocedural airway complications, and tube dislodgement) between patients maintained on ASA 325 mg and patients not on antiplatelet or anticoagulation therapy. Results No significant bleeding episodes occurred in patients on ASA 325 mg, compared to three episodes in patients not on ASA 325 mg (p = 0.37). A patient in each group had aspiration pneumonia possibly related to tube placement. There were no other notable secondary outcomes, including intraprocedural airway complications in this population with complex head and neck anatomy. Conclusion These findings suggest that holding ASA 325 mg in patients undergoing percutaneous gastrostomy tube placement is not necessary, especially in patients in whom holding ASA would pose considerable risk. Further multi-institutional longitudinal study is warranted to validate these results.

Objective Lung shunt fraction studies using technetium-99 m macro aggregated albumin are routinely performed before yttrium-90 radioembolization regardless of underlying liver malignancy type. This study evaluates the role of lung shunt fraction studies in hepatocellular carcinoma compared to non-hepatocellular carcinoma liver tumors. Methods A single-institution retrospective analysis of all pre-yttrium-90 technetium-99 m macro aggregated albumin lung shunt fraction studies between November 2012 to March 2018 was performed. Patient variables including age, underlying malignancy, laboratory values, lung shunt fraction, and severity of liver disease were compared between hepatocellular carcinoma and non-hepatocellular carcinoma cases. Results A total of 734 technetium-99 m macro aggregated albumin studies were identified in 653 patients. Among these cases, the liver tumor was hepatocellular carcinoma in 368 (50.1%), colorectal cancer in 112 (15.3%), neuroendocrine tumor in 89 (12.1%), cholangiocarcinoma in 59 (8.0%), breast cancer in 27 (3.7%), and other metastatic malignancies in 79 (10.7%). The mean lung shunt fraction for non-hepatocellular carcinoma cases was 7.4%, which was significantly lower than the mean lung shunt fraction, 11.7%, for hepatocellular carcinoma cases (P = 0.0001). In only one non-hepatocellular carcinoma case was yttrium-90 radioembolization not pursued due to high lung shunt fraction (69.3%), wherein large scale shunting was grossly apparent on angiography in a patient with metastatic gastrointestinal stromal tumor. In comparison, the lung shunt fraction was too high to pursue radioembolization in 37 hepatocellular carcinoma cases (mean lung shunt fraction 35.1%). Conclusion Lung shunt fraction appears low among patients with non-hepatocellular carcinoma liver malignancies. Further analysis examining the necessity of pre-Y90 technetium-99 m macro aggregated albumin lung shunt fraction studies in patients with non-hepatocellular carcinoma malignancies is warranted, since a consolidated yttrium-90 radioembolization without prior lung shunt fraction evaluation could reduce resource consumption, improve workflows, and patient access.

The purpose of this study is to compare the motivations of interventional radiology (IR) residency, IR fellowship, and diagnostic radiology (DR) applicants.A questionnaire was distributed to IR integrated residency and IR fellowship applicants for the 2018 National Resident Matching Program (NRMP) Match. Survey respondents scored the influence of 13 aspects of IR on their career decision. These results were combined with a previously published survey of DR residency applicants from 2016 who were asked the same questions. Pairwise comparisons to survey responses were made between IR residency and IR fellowship as well as IR residency and DR residency respondents.There were 202 of 657 DR residency respondents (response rate 30.7%), 114 of 295 IR residency respondents (response rate 38.6%), and 70 of 169 IR fellowship respondents (response rate 41.4%). Compared with DR respondents, IR residency respondents rated the following factors more positively: influence of a mentor (P = .030), perceived job satisfaction (P.001), job market (P .001), salary (P.001), intellectual stimulation (P = .030), the use of emerging or advanced technology (P.001), and the visual nature of the field (P .001). In contrast, DR residency respondents rated flexible work hours (P.001), physics (P.001), and competitiveness of the application process (P.001) more positively than IR respondents. Compared with IR fellowship respondents, IR residency respondents rated flexible work hours (P = .002), the job market (P = .020), physics (P.001), and salary (P.001) more positively, and competitiveness (P = .002) was felt to be more negative for residency applicants.The motivations for pursuing IR residency differ from both DR residency and IR fellowship. Understanding these motivations can help to recruit top quality IR residency applicants.

Postpartum hemorrhage (PPH) affects approximately 14 million women yearly, accounts for 25% of delivery-related deaths in the world and is the main cause of emergency peripartum hysterectomy. Traditionally, PPH is defined as at least 500 mL of blood loss after vaginal delivery or 1000 mL of blood loss after cesarean-section. However, several authors have suggested a simpler definition to include women who experience hemodynamic instability after birth regardless of amount of blood loss. Secondary PPH is defined as bleeding that occurs after 24 hours to 12 weeks from delivery, and can fail medical management. It is imperative that the clinical team recognize the signs and symptoms of secondary PPH and, if necessary, consult the interventional radiology service for a minimally invasive option of uterine artery embolization, which has shown up to 95% success rate.

To identify differences in mortality or length of hospital stay for mothers treated with uterine artery embolization (UAE) or hysterectomy for severe postpartum hemorrhage (PPH), as well as to analyze whether geographic or clinical determinants affected the type of therapy received.This National Inpatient Sample study from 2005 to 2017 included all patients with live-birth deliveries. Severe PPH was defined as PPH that required transfusion, hysterectomy, or UAE. Propensity score weighting-adjusted demographic, maternal, and delivery risk factors were used to assess mortality and prolonged hospital stay.Of 9.8 million identified live births, PPH occurred in 31.0 per 1,000 cases. The most common intervention for PPH was transfusion (116.4 per 1,000 cases of PPH). Hysterectomy was used more frequently than UAE (20.4 vs 12.9 per 1,000 cases). The following factors predicted that hysterectomy would be used more commonly than UAE: previous cesarean delivery, breech fetal position, placenta previa, transient hypertension during pregnancy without pre-eclampsia, pre-existing hypertension without pre-eclampsia, pre-existing hypertension with pre-eclampsia, unspecified maternal hypertension, and gestational diabetes (all P.001). Delivery risk factors associated with greater utilization of hysterectomy over UAE included postterm pregnancy, premature rupture of membranes, cervical laceration, forceps vaginal delivery, and shock (all P.001). There was no difference in mortality between hysterectomy and UAE. After balancing demographic, maternal, and delivery risk factors, the odds of prolonged hospital stay were 0.38 times lower with UAE than hysterectomy (P.001).Despite similar mortality and shorter hospital stays, UAE is used far less than hysterectomy in the management of severe PPH.

PURPOSE To quantify changes in the management of pediatric patients with isolated splenic injury from 2007 to 2015. MATERIALS AND METHODS Patients under 18 years old with registered splenic injury in the National Trauma Data Bank (2007-2015) were identified. Splenic injuries were categorized into 5 management types: nonoperative management (NOM), embolization, splenic repair, splenectomy, or a combination therapy. Linear mixed models accounting for confounding variables were used to examine the direct impact of management on length of stay (LOS), intensive care unit (ICU) days, and ventilator days. RESULTS Of included patients (n = 24,128), 90.3% (n = 21,789), 5.6% (n = 1,361), and 2.7% (n = 640) had NOM, splenectomy, and embolization, respectively. From 2007 to 2015, the rate of embolization increased from 1.5% to 3.5%, and the rate of splenectomy decreased from 6.9% to 4.4%. Combining injury grades, NOM was associated with the shortest LOS (5.1 days), ICU days (1.9 days), and ventilator days (0.5 day). Moreover, splenectomy was associated with longer LOS (10.1 days), ICU days (4.5 days), and ventilator days (2.1 days) than NOM. The average failure rate of NOM was 1.5% (180 failures/12,378 cases). Average embolization failure was 1.3% (6 failures/456 cases). Splenic artery embolization was associated with lower mortality than splenectomy (OR: 0.10, P

To evaluate the utilization and efficacy of various treatments for management of adult patients with splenic trauma, highlighting the evolving role of splenic artery embolization.The National Trauma Data Bank (NTDB) was queried for patients who sustained splenic trauma between 2007 and 2015, excluding those with death on arrival and selected nonsplenic high-grade injuries. Patients were categorized into (1) nonoperative management (NOM), (2) embolization, (3) splenectomy, (4) splenic repair, and (5) combined treatment groups. Evaluated outcomes included hospital length of stay (LOS), intensive care unit LOS, mortality, and NOM and embolization failures.Overall, 117,743 patients with splenic predominant trauma were included in this study. Over the 9-year study period, 85,793 (72.9%) were treated with NOM, 21,999 (18.9%) with splenectomy, 3895 (3.3%) with embolization, and 2131 (1.8%) with splenic repair. From 2007 to 2015, mortality rates declined from 7.6% to 4.7%. The rate of NOM did not significantly change over time, while embolization increased 369% (1.3%-4.8%). Failure of NOM was 4.4% in 2007 and decreased to 3.4% in 2015. Across all injury grades, NOM had the shortest LOS (8.3 days), followed by splenic repair (12.3), embolization (12.6), and splenectomy (13.8) (p0.001). When adjusted for various clinical factors including severity of splenic injury, mortality rates were 7.1% for splenectomy, 3.2% for embolization, and 2.5% for NOM.Most patients with splenic-dominant blunt trauma are managed with NOM. Over time, the use of embolization has increased while open surgery has declined, and mortality has improved for all treatment methods. Compared to splenectomy, embolization is associated with shorter hospital LOS but is still used relatively infrequently.

Retrospective review.To ascertain impact of preprocedural magnetic resonance imaging (MRI) or nuclear medicine Tc99m-DMP scintigraphy on the treatment plan when compared with plain films and/or computed tomography prior to vertebral augmentation procedures.Over 1 million vertebral compression fractures (VCFs) occur in the United States annually with over 150,000 individuals hospitalized each year. Physical examination and history are essential to the workup of VCFs, but imaging remains necessary for confirming the diagnosis. VCFs can be imaged with various modalities and there is limited data on the comparative effectiveness of different imaging modalities.Six hundred fifty consecutive patients treated with vertebral augmentation at a single institution between May of 2013 and April of 2018 were reviewed. Preprocedure imaging of the spine obtained within 30 days prior to the procedure were reviewed. Preprocedure imaging results were cross-referenced against the levels treated by vertebral augmentation to determine whether there was a change in the levels treated after receiving an MRI or NM imaging study.Three hundred sixty-three patients had adequate imaging for inclusion. One hundred fifty-four of these 363 patients (42.4%) had an alteration of their treatment plan based upon the MR or NM imaging. Fewer vertebral levels were treated in 33, different levels were treated in 41, and more levels were treated in 80 patients.MRI or nuclear medicine bone scan imaging prior to vertebral augmentation altered the location and number of levels treated in a large percentage of patients, adding specificity to treatment over findings on radiographs or computed tomography alone.3.

Rationale and Objectives Historically, patients undergoing image-guided percutaneous gastrostomy tube placement have been admitted overnight with feeds commencing 12–24 hours postprocedure. With new expedited feeding protocols starting 3–4 hours postprocedure, same-day discharge is now possible. The purpose of this study was to evaluate the safety and cost of image-guided percutaneous gastrostomy tube placement as an outpatient procedure. Materials and Methods In this retrospective study, 131 patients (age 63.9 ± 11.6; 34% female) underwent gastrostomy tube placement as an outpatient procedure with expedited feeding protocol versus 40 patients (age 61.3 ± 12.6; 38% female) who were hospitalized overnight with feeds starting at 12–24 hours, primarily based on operator preference. The two groups were compared regarding complications within 90 days of procedure. Using a subgroup of 33 consecutive patients, procedural costs (total combined insurer and patient payments for professional and hospital services) for outpatients vs. hospitalized patients were compared. Results Complication rates were similar (p = 0.64) for gastrostomy tubes placed on outpatients (0.17 complications/procedure: 4 bleeding, 2 aspiration pneumonia, 1 abdominal abscess, 4 significant pain, 6 cellulitis, 1 surgical consult, 4 malpositioned/fractured tubes) and hospitalized patients (0.20 complications/procedure: 1 aspiration pneumonia, 1 significant pain, 3 cellulitis, 1 surgical consult, 2 fractured tubes). Total combined insurer and patient payments were similar ($2193/outpatient vs $2701/hospitalized patient; p= 0.52). Conclusion Outpatient image-guided percutaneous gastrostomy tube placement with an expedited feeding protocol is a safe and cost-comparable alternative to historic overnight hospitalization. Further prospective investigation with a larger sample is warranted.

The aim of this study was to evaluate the contemporary use of procedural interventions to treat symptomatic uterine fibroids and assess associated health care system costs.Using the IBM Watson MarketScan Commercial Claims and Encounters database for 2009 to 2015 and relevant International Classification of Diseases diagnosis codes, women aged 18 to 55 years with clinically significant uterine fibroids were identified. Using Current Procedural Terminology codes, relevant procedural interventions were identified (hysterectomy, endometrial ablation, myomectomy, and uterine fibroid embolization [UFE]). Costs were defined as total actual payments by insurers and patients (per procedure and per episode of care) and were adjusted and compared using generalized linear models.Of 241,757 invasive procedures for fibroids, hysterectomy was most common (76.5%), followed by endometrial ablation (14.5%), myomectomy (4.7%), and UFE (4.3%). Hysterectomy was more common in older women and those in rural areas (65.2% of patients40 years of age, 77.6% of those 40-49 years of age, and 83.6% of those 50-55 years of age; 83.9% of patients outside versus 75.3% within metropolitan statistical areas). Per procedure, adjusted mean costs were $3,188 (95% confidence interval [CI], $3,114-$3,264) for hysterectomy, $2,781 (95% CI, $2,695-$2,870) for ablation, $4,436 (95% CI, $4,256-$4,623) for myomectomy, and $6,161 (95% CI, $5,736-$6,617) for UFE. Adjusted mean costs for entire episodes of care were $14,676 (95% CI, $14,496-$14,858) for hysterectomy, $6,702 (95% CI, $6,534-$6,875) for endometrial ablation, $14,791 (95% CI, $14,465-$15,125) for myomectomy, and $13,873 (95% CI, $13,182-$14,599) for UFE.Of invasive procedures for symptomatic uterine fibroids, hysterectomy was used more frequently than endometrial ablation, myomectomy, and UFE combined. Per procedure and per episode, ablation was least costly. Costs per episode were similar for hysterectomy, myomectomy, and UFE.

To evaluate the comparative outcome and cost of vascular plugs versus coils for internal iliac artery embolization prior to endovascular aortic aneurysm repair. A search was performed for internal iliac artery embolization studies in adult patients from January 2005 to July 2018. Inclusion criteria included embolization of unilateral or bilateral IIAs with either coils or plug(s) prior to endovascular aortic repair. Meta-analysis was performed using a fixed effects model with the inverse variance-weighted average method to determine pooled differences in surgical time, fluoroscopy time, radiation exposure, number of devices used, cost of devices, and post-embolization buttock claudication. Heterogeneity was assessed using the Chi-square statistic. Pooled outcomes were compared, and quality assessments were evaluated using the Newcastle–Ottawa scale. Six studies met inclusion criteria. One hundred and eighty-one patients were included in the study, of which 87 were in the plug group and 94 in the coil group. Vascular plug use led to 35.32 min shorter surgery time (p

Interventional radiologists are often called for emergent control of abnormal uterine bleeding. Bleeding, even heavy bleeding as a result of uterine fibroids is not a common emergent procedure; instead, pregnancy and pregnancy related conditions, trauma and malignancy associated with bleeding can be the source of many interventional radiology on call events or procedures. Postpartum hemorrhage (PPH) is the most common cause, and is defined as blood loss of 500mL after vaginal delivery or 1000mL after cesarean section. Several authors have suggested a simpler definition of any amount of blood loss that creates hemodynamic instability in the mother. Regardless, PPH can be a life-threatening emergency and is a leading cause of maternal mortality requiring prompt action. Primary PPH is bleeding within the first 24 hour of delivery and secondary PPH is hemorrhage that occurs more than 24 hour after delivery. In addition to death, other serious morbidity resulting from postpartum bleeding includes shock, adult respiratory distress syndrome, coagulopathy, and loss of fertility due to hysterectomy. Transcatheter uterine artery embolization was first introduced as a treatment for PPH in 1979. It is a nonsurgical, minimally invasive, extremely safe and effective treatment for controlling excessive bleeding of the female reproductive track usually after conservative measures have failed, yet somewhat underused. Referring providers have limited awareness of the procedure. In hospitals where interventional radiologists have the experience and technical expertise to perform pelvic arteriography and embolization, this therapeutic option can play a pivotal role in the management of emergent obstetric hemorrhage.

The aim of this article is to review the available evidence regarding image-guided percutaneous cryoneurolysis, with a focus on indications, technique, efficacy, and potential complications.Percutaneous image-guided cryoneurolysis is safe and effective for the management of several well-described syndromes involving neuropathic pain. Additional rigorous prospective study is warranted to further define the efficacy and specific role of these interventions.

A gravida 4 para 1021, 41-year-old woman postcaesarean section at 39 weeks and 1 day with clinically significant haemorrhage required embolisation of unique uterine arterial collaterals. She had persistent haemorrhage after initial bilateral uterine artery embolisation, and on further investigation she was found to have a hypertrophied right round ligament artery. Once successful embolisation of this abnormal right round ligament artery was completed using a combination of Gelfoam and coils, haemostasis was achieved. She had rapid clinical improvement, no complications and no further admissions on postprocedural follow-up over a year and a half later.
