    Abstract:
    PURPOSE: This study was designed to evaluate the clinical outcome and patients' satisfaction after a 5 year follow-up period for pelvic congestion syndrome (PCS) coil embolization in patients who suffered from chronic pelvic pain that initially consulted for lower limb venous insufficiency. METHODS: A total of 202 patients suffering from chronic pelvic pain were recruited prospectively in a single center (mean age 43.5 years; range 27-57) where they were being treated for lower limb varices. Inclusion criteria were: lower limb varices and chronic pelvic pain (>6 months), >6 mm pelvic venous caliber in ultrasonography, and venous reflux or presence of communicating veins. Both ovarian and hypogastric veins were targeted for embolization. Pain level was assessed before and after embolotherapy and during follow-up using a visual analog scale (VAS). Technical and clinical success and recurrence of leg varices were studied. Patients completed a quality questionnaire. Clinical follow-up was performed at 1, 3, and 6 months and every year for 5 years. RESULTS: Technical success was 100%. Clinical success was achieved in 168 patients (93.85%), with complete disappearance of symptoms in 60 patients (33.52%). Pain score (VAS) was 7.34 ± 0.7 preprocedural versus 0.78 ± 1.2 at the end of follow-up (P < 0.0001). Complications were: groin hematoma (n = 6), coil migration (n = 4), and reaction to contrast media (n = 1). Twenty-three cases presented abdominal pain after procedure. In 24 patients (12.5%), there was recurrence of their leg varices within the follow-up. The mean degree of patients' satisfaction was 7.4/9. CONCLUSIONS: Coil embolization of PCS is an effective and safe procedure, with high clinical success rate and degree of satisfaction.
