BACKGROUND: Pelvic congestion syndrome (PCS) is a recognized cause of chronic pelvic pain resulting from ovarian or pelvic venous reflux or obstruction, diagnosed mainly by transvaginal duplex and treated medically, surgically, or with endovascular embolization. We aimed this work to compare and emphasize the outcome of two endovenous techniques, foam sclerotherapy and sandwich, for treatment of ovarian vein reflux. METHODS: This prospective randomized controlled study was carried out on 40 female patients, with PCS lasting more than six months and did not respond to medical therapy, with refluxing ovarian vein and a diameter larger than 6 mm. The primary outcome was symptomatic improvement, defined as ≥50% reduction in VAS score from baseline. Secondary outcomes were complications. Patients were divided into two equal groups. Group A (n = 20) underwent foam sclerotherapy with polidocanol 3%, while group B (n = 20) underwent the sandwich technique. RESULTS: Forty patients were included in our study and were followed up for 1 year after the procedure. The pre-procedural vein diameter was significantly larger in patients with diameters >8 mm compared to those with 6-8 mm (P 8 mm) (P 8 mm), supporting treatment selection based on ovarian vein diameter.
