Heterotopic cervical pregnancy is a rare and potentially dangerous condition where the challenge is the removal of the ectopic pregnancy while preserving the intrauterine one. We present the case of an otherwise healthy 36-year-old woman with heterotopic cervical pregnancy after an IVF cycle for tubal infertility. At 6.5 weeks after a consultation with gynecologists and interventional radiologists, the patient agreed to undergo microwave ablation of the cervical pregnancy. Monthly ultrasound examination showed the persistence of non homogeneous and vascularized tissue in the cervix. Intrauterine pregnancy continued without complications until 37 weeks when a cesarean section was performed for sudden and profuse bleeding, in the presence of uterine contractions. A healthy baby girl was delivered, and the postoperative course was otherwise uncomplicated. Heterotopic cervical pregnancies are rare, and no consolidated and risk-free treatments are available at the moment. Here, we present a case of heterotopic cervical pregnancy treated successfully and without complications with microwave ablation.

To determine the effectiveness of liver reporting and data system (LI-RADS) to diagnose hepatocellular carcinoma (HCC) and to retrospectively evaluate its impact on the adopted therapeutic strategy. Preoperative imaging of 40 of 350 patients (median age 66, 31 M/9 F) submitted to liver resection for suspected HCC, between January 2008 and August 2019, has been retrospectively analyzed by two radiologists with different expertise, according to CT/MRI LI-RADS® v2018, both blinded to clinical and pathological results and untrained to using aforementioned scoring system. The perfect agreement between the readers was about 62.5% (25/40) (Cohen k: 0.41), better for LR-5 category (16/25) and higher in magnetic resonance imaging (MRI) investigations (68%; 13/19), which has been demonstrated the modality of choice for diagnosis of high probable and certain HCC, with arterial phase hyperenhancement as the most sensitive and accurate major feature. Compared to final histology, LR4 and LR5 scores assigned by senior radiologist reached sensitivity, specificity, positive and negative predictive values (PPV, PNV) and diagnostic accuracy of 90,9%, 29,0%, 93,8%, 62,5% and 87,5%, respectively, slightly higher than junior’s ones. Misdiagnosis of HCC was done by both radiologists in the same two patients: 1 primary hepatic lymphoma (PHL) and 1 regenerative liver nodule (RLN). If LI-RADS would have been applied at the time of pre-surgical imaging, treatment planning would be modified in 10% of patients (4/40); the patient scheduled as LR-3 and finally resulted a focal nodular hyperplasia would have avoided liver resection. Application of LI-RADS, especially on MRI, may provide a more accurate evaluation of suspected HCC. PHL and RLN are the Achille’s heels according to our experience.

To evaluate the incidence of in-stent restenosis (ISR) at 12-month follow-up, in patients treated with new dual-layer Roadsaver (Terumo Corp, Tokyo, Japan) carotid artery stent (CAS). Thirteen patients underwent CAS and received a Roadsaver. Neurological examination was performed in all patients. Carotid stenosis was revealed by Doppler ultrasound (DUS) and multidetector CT (MDCT) scan. Four patients presented a peak systolic velocity (PSV) between 130 and 150 cm/s, six a PSV between 150 and 180 cm/s, and three a PSV > 180 cm/s. MDCT gave further anatomic information. Direct stenting was performed in 11 (84.6%) cases, whereas in 2 (15.4%) cases predilatation was required. In all cases postdilatation was performed. Technical and clinical success and safety were evaluated. Stent patency was evaluated during the 12-month follow-up. Technical success was achieved in all cases. In three patients a nonsignificant residual stenosis

Radiofrequency ablation is a minimally invasive procedure alternative to surgery to treat benign thyroid nodules causing compressive symptoms. Tolerability of this procedure, aimed at treatment of benign conditions, is fundamental. In this study, we evaluated if local anesthesia should be enough to reduce both hospital costs and sedation-related risks for the patient, avoiding deep sedation and presence of the anesthesiologist. From July 2017 to August 2018, 14 consecutive patients (mean age 60.1 years) were treated and divided in two groups: Group A (7 patients) underwent systemic sedoanalgesia (intravenous remifentanil/fentanyl ± intravenous midazolam ± intravenous acetaminophen/nonsteroidal anti-inflammatory drugs) + subcutaneous anesthesia (lidocaine), with anesthesiologist. Group B (7 patients) underwent mild systemic sedoanalgesia (oral solution morphine sulfate + intravenous midazolam + intravenous acetaminophen) + both subcutaneous and subcapsular anesthesia (mepivacaine + bupivacaine), without anesthesiologist. Tolerability, sedation grade (Ramsay scale), total opioid dose, complications, and results at 12 months were analyzed and compared. Mean tolerability was 9.4 in group A and 8.9 in group B (p: 0.786). Mean sedation grade was 3.86 in group A and 2.71 in group B (p: 0.016). Mean total opioid dose was 70.9 mg in group A and 10 mg in group B (p:0.00015). No complications were observed. At 12 months, mean volume reduction was 56.1% in the group A and 60% in the group B. In thyroid radiofrequency ablation, subcapsular anesthesia can decrease both total opioid dose and level of patient's sedation without significant differences in tolerability, allowing to perform ablation without the anesthesiologist.

To evaluate outcomes of uterine conserving surgery with occlusion balloon technique. A critical review of the complications was performed. Between 2010 and 2016, pregnant women, with a prenatal diagnosis of morbidly adherent placenta (MAP), were treated with occlusion balloon catheters in both internal iliac arteries. Parameters such as need for hysterectomy, incidence of PPH, grade of MAP, estimated blood loss during delivery (EBL) and transfusion requirements, mean recovery time and duration of the balloon inflation, were collected and reviewed. Complications requiring further management were analysed. Thirty-seven women with MAP underwent prophylactic occlusion balloon placement (POBC). Mean recovery was 4.48 days (range 2–10). Catheters were successfully positioned and balloons inflated in obstetric theatre following caesarean delivery in 100% of the cases. The uterus was conserved in every case. The MAP grades were 20 percreta, 3 increta and 14 accreta. The EBL was not statistically different between the different grades of placentation. There was a statistically significant association in the number of patients requiring blood transfusions and the degree of placental invasion (p = 0. 0119). PPH occurred in 5 patients (13.5%) and arterial thrombosis in 4 patients (11%). The EBL during delivery was significantly higher (2811 mL) in patients with complications (p = 0.0102). Furthermore, the group of patients that had complications required statistically significant more blood transfusions compared to those without complications (p = 0.0001). No maternal mortality or foetal morbidity occurred. The utilisation of Prophylactic occlusion balloon catheters allows uterine conserving surgery to be performed safely with few maternal complications.

The aim of this study was to compare the Intravoxel Incoherent Motion (IVIM) parameters between healthy Peripheral Zone (PZ), Benign Prostatic Hyperplasia (BPH) and Prostate Cancer (PCa) and compare them to assess whether there was correlation with Gleason Score (GS) grading system. Thirty-one patients with suspect of PCa underwent 1.5T Multi-Parametric Magnetic Resonance Imaging (MP-MRI) with endorectal coil with a protocol including T2WI, DWI using 10 b values (0, 10, 20, 30, 50, 80, 100, 200, 400, 1000 s/mm2) and DCE. Monoexponential and IVIM model fits were used to calculate both apparent diffusion coefficient (ADC) and the following IVIM parameters: molecular diffusion coefficient (D), perfusion-related diffusion coefficient (D*) and perfusion fraction (f). The ADC and D values were significantly lower in the PCa (0.70 ± 0.16 × 10−3 mm2/s and 0.88 ± 0.31 × 10−3 mm2/s) compared to those found in the PZ (1.22 ± 0.20 × 10−3 mm2/s and 1.78 ± 0.34 × 10−3 mm2/s) and in the BPH (1.53 ± 0.23 × 10−3 mm2/s and 1.11 ± 0.28 × 10−3 mm2/s). The D* parameter was significantly increased in the PCa (5.35 ± 5.12 × 10−3 mm2/s) compare to the healthy PZ (3.02 ± 2.86 × 10−3 mm2/s), instead there was not significantly difference in the PCa compare to the BPH (5.61 ± 6.77 × 10−3 mm2/s). The f was statistically lower in the PCa (9.01 ± 5.20%) compared to PZ (10.57 ± 9.30%), but not significantly different between PCa and BPH (9.29 ± 7.29%). The specificity, sensitivity and accuracy of T2WI associated with DWI and IVIM were higher (100, 98 and 99%, respectively) than for T2WI/DWI and IVIM alone (89, 92 and 90%, respectively). Only for ADC was found a statistical difference between low- and intermediate-/high-grade tumors. Adding IVIM to the MP-MRI could increase the diagnostic performance to detect clinically relevant PCa. ADC values have been found to have a rule to discriminate PCa reliably from normal areas and differed significantly in low- and intermediate-/high-grade PCa. In contrast, IVIM parameters were unable to distinguish between the different GS.

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy after hepatocellular carcinoma. Complete surgical resection remains the only potentially curative option for patients with ICC. However, until now, early diagnosis with potential surgical intervention has been the exception rather than the rule with only 30% of patients qualifying for attempted surgical cure. Many patients are unresectable because of disease stage, anatomic conditions, medical comorbidities, and small future remnant liver. Interventional radiology procedures are available for these types of patients with intra-arterial therapies and/or ablative treatments both for curative and for palliative treatment. The goals of interventional therapy are to control local tumor growth, to relieve symptoms, and to improve and preserve quality of life. The choice of treatment depends largely on tumor extent and patient performance. No randomized studies exist to compare treatments. The present review describes the current evidence of the interventional treatments in the management of the ICC. Moreover, interventional procedures available to increase the future liver reserve before surgery were analyzed.
