Article Synopsis
  • This study investigates the effectiveness of uterine artery embolization (UAE) with gelatin foam to manage delayed bleeding caused by vascularized retained products of conception (vRPOC) after abortion or miscarriage during a 5-year period at 11 French hospitals.
  • Out of 224 patients evaluated, 94.2% experienced clinical success, although 7.3% showed persistent vRPOC at imaging follow-ups, with some minor and major complications reported.
  • The results suggest that while UAE with gelatin foam is generally safe and effective, certain factors like having a hypertrophic uterine artery and using gelatin foam torpedoes may increase the risk of persistent bleeding issues.

Article Synopsis
  • The study examined features linked to successful clinical outcomes after prostate artery embolization (PAE) for those with symptomatic benign prostate hypertrophy (BPH) over short- and mid-term periods.
  • A total of 88 adult patients were analyzed, revealing a high success rate of 81.8% at 3 months and 60.2% at 2 years post-treatment.
  • Results indicated that while radiomics scores had limited predictive value, factors such as Wasserman classification and a significant reduction in international prostate symptom score (IPSS) at 3 months were good indicators of mid-term treatment success.

Objective: To assess the efficacy and safety of percutaneous image-guided cryoablation of adenomyomas MATERIAL AND METHODS: Five symptomatic women who wanted to preserve their uterus and fertility underwent a single session of percutaneous image-guided cryoablation of adenomyoma. Three to six 17-gauge cryoprobes were introduced percutaneously into the adenomyoma under ultrasound and laparoscopy guidance. Clinical efficacy was defined as the diminution of the Visual Analogue Scale of pain (VAS), the decrease in uterine bleeding and the improvement of quality of life assessed by the endometriosis health profile 5 (EHP-5) 12 months after treatment.

Interventional radiology shows promises in the field of women's health, particularly in pelvic interventions. This review article discusses the latest advancements in interventional radiology techniques for pelvic conditions affecting women including adenomyosis, abdominal wall endometriosis and uterine leiomyoma. Extraperitoneal endometriosis involving the abdominal wall may be treated by percutaneous thermal ablation, such as cryoablation, whereas uterine leiomyoma and adenomyosis can be managed either using percutaneous thermal ablation or using uterine artery embolization.

Purpose: The aim of this study was to ascertain whether radiomics data can assist in differentiating small (<4 cm) clear cell renal cell carcinomas (ccRCCs) from small oncocytomas using T2-weighted magnetic resonance imaging (MRI).

Material And Methods: This retrospective study incorporated 48 tumors, 28 of which were ccRCCs and 20 were oncocytomas. All tumors were less than 4 cm in size and had undergone pre-biopsy or pre-surgery MRI.

Background: Partial nephrectomy (PN) is the gold standard treatment for cT1b renal tumors. Percutaneous guided thermal ablation (TA) has proven oncologic efficacy with low morbidity for the treatment of small renal masses (<3 cm). Recently, 3D image-guided robot-assisted PN (3D-IGRAPN) has been described, and decreased perioperative morbidity compared to standard RAPN has been reported.

Objective: We investigated the efficacy of iliofemoral venous stenting in women of childbearing age treated for post-thrombotic syndrome (PTS) and assessed the influence of pregnancy on stent occlusion.

Methods: A retrospective analysis was conducted on women of childbearing age who underwent endovascular stenting for PTS due to chronic iliocava occlusion across 15 centers from 2009 to 2020. The study assessed pregnancy rates, primary patency rates, secondary patency rates, and clinical efficacy using the Villalta score for PTS severity and the Chronic Venous Disease Quality of Life Questionnaire - version 20 (CIVIQ-20), 6-12 months after the procedure.

To evaluate indirect criteria of pelvic venous insufficiency (PVI) of a short tau inversion recovery (STIR) sequence retrospectively compared with phlebographic findings. Between 2008 and 2018, 164 women who had received MRI and phlebography for pelvic congestion syndrome (60), varicose veins in the lower limbs (45), both (43), or other symptoms (16) were included. The presence of periuterine varicosities and perivaginal varicosities were compared to the findings of phlebography: grading of left ovarian vein reflux and presence of internal pudendal or obturator leak.
