Proximal coil occlusion preceding distal sclerotherapy in patients with pelvic congestion syndrome: A multicenter, retrospective study.

Objective: We investigated the efficacy, feasibility, and safety of proximal coil occlusion preceding distal sclerotherapy (PCODS) for patients with pelvic congestion syndrome (PCS).

Methods: We performed a multicenter, retrospective cohort study of 94 patients with PCS who had undergone PCODS and 53 patients who had undergone standard endovascular embolization (control group) between June 2014 and April 2020. The primary end point was the clinical remission rate and the secondary end points were the operative time, total fluoroscopy time, radiation dose, overall length of coils used per case, and adverse events.
