Abstract:Background and Aims Pelvic venous disease (PeVD) is an important vascular cause of chronic pelvic pain, with ovarian vein reflux being the most common underlying mechanism. Ovarian vein embolization has been proven effective; however, key technical aspects-including embolization extent, coil number, and the need for concomitant treatment of other pelvic venous abnormalities-remain controversial. This study aimed to evaluate the short- and mid-term efficacy and safety of a simplified strategy using left ovarian vein coil embolization combined with sclerotherapy for the treatment of PeVD.Methods A retrospective analysis was performed on 55 female patients with PeVD treated between February 2023 and February 2024. All patients were diagnosed using ultrasound, CT venography, and venography, and underwent left ovarian vein coil embolization combined with sclerotherapy. Follow-up assessments were conducted at 1, 3, 6, and 12 months post-procedure, including visual analog scale (VAS) scores, symptom improvement, and complications. Doppler ultrasound at 3 months was used to evaluate ovarian vein occlusion and pelvic venous changes.Results Technical success was achieved in all patients. At 12 months, the mean VAS score significantly decreased from 7.2±1.2 preoperatively to 2.9±2.8 (P<0.01). Symptom improvement was observed in 81.8% of patients, with complete symptom resolution in 50.9%. Ultrasound at 3 months confirmed complete ovarian vein occlusion in all cases, and the diameter of the left parauterine vein significantly decreased compared with baseline [(7.1±1.4) mm vs. (3.4±0.7) mm, P<0.001]. The overall complication rate was 14.5%, predominantly transient pelvic pain, which resolved with conservative management.Conclusion A simplified embolization strategy using left ovarian vein coil embolization combined with sclerotherapy is safe and effective for patients with PeVD predominantly caused by left ovarian vein reflux and represents a reliable minimally invasive treatment option.
