Pelvic Venous Disorders in Women due to Pelvic Varices: Treatment by Embolization: Experience in 520 Patients.

The purpose of this study was to determine the efficacy and safety of embolization treatment in pelvic venous disorders in women refluxing in the ovarian and or internal iliac veins in women with chronic pelvic pain. A retrospective study conducted from January 2000 to June 2017 in 617 patients diagnosed with pelvic venous disorders (PeVDs) with a mean age of 43.2 ± 7.2 years were treated using an embolization procedure. A total of 520 were included, and 97 patients were excluded. The main inclusion criteria were PeVD symptoms for more than 6 months and transvaginal Doppler ultrasonography (TV-DUS) diagnosis of varicose veins in the pelvis with a diameter greater than 6 mm. The main objective was to embolize the 4 main pelvic venous plexi (ovarian and internal iliac veins) whenever possible. Follow-up was performed using clinical symptoms (visual analog scale) and TV-DUS at 1, 3, 6, and 12 months and then every year up to 5 years. The technical success (embolization of the 4 main pelvic veins) was achieved in 84.4% of the patients. The average follow-up was 58.7 ± 5.7 months. The visual analog scale was improved from 7.63 ± 0.9 points pretreatment to 0.91 ± 1.5 at 5 years. A total of 26 patients (5%) presented with symptom recurrence and pelvic varicose veins. There were 57 minor complications (10.9%) and 11 major complications (2.1%), with 7 cases (1.34%) of device migration to the lung. The embolization of pelvic varicose veins is a safe and effective procedure. The selection of the embolic agents and the number of veins needed to be treated.
