Effectiveness and safety of detachable fibered coils as a single therapy for embolization in venous origin chronic pelvic pain

Objectives To investigate the effectiveness and safety of endovascular treatment by embolization with detachable fibered coils of insufficient pelvic veins, as the primary cause of Venous Origin Chronic Pelvic Pain (VOCPP). Methods This observational, retrospective study analyzes data from the PELVIC registry from 2014 to 2022. Sociodemographic, diagnostic, preoperative, intraoperative, and postoperative follow-up variables were reported. Results A total of 255 patients were included, with follow-up periods up to 5 years. The study’s effectiveness was significant with a 60% decrease in pelvic pain at the first follow-up after treatment measured by a Visual Analogue Scale ( p = 0.001). There were also decreases in the severity levels of dyspareunia ( p = 0.03), dysmenorrhea ( p = 0.12) and presence of Pelvic Venous Disorders symptoms in general (−43.8%; p = 0.001). No major adverse events were recorded. Only 5 patients (2%) experimented technical issues in coil implantation, all of them solved in situ. Conclusion The treatment of VOCPP by embolization with detachable fibered coils has proven to be an effective and safe option for insufficient pelvic veins.
