    Abstract:
    BACKGROUND: Pelvic congestion syndrome (PCS) is defined as noncyclical pelvic pain or discomfort caused by dilated parauterine, paraovarian, and vaginal veins. PCS is typically characterized by ovarian venous incompetence that may be due to pelvic venous valvular insufficiency, hormonal factors, or mechanical venous obstruction. METHODS: We describe a case of a 38-year-old multiparous female with a history of pelvic pressure, vulvar varices, and dyspareunia. She underwent left gonadal vein coil embolization in 2014 for PCS that lead to symptomatic relief of her pain. Four years later, the patient returned for recurrent symptoms. Magnetic resonance venogram demonstrated dilated pelvic varices. The previously embolized left gonadal vein remained thrombosed, and there was no evidence of right gonadal vein insufficiency. However, catheter-based venography revealed a large, dilated, and incompetent median sacral vein. RESULTS: Pelvic venography demonstrated left gonadal vein embolization without any evidence of reflux. The right gonadal vein was also nondilated without reflux. Internal iliac venography showed large cross-pelvic collaterals and retrograde flow via a large, dilated median sacral vein. Coil embolization of the median sacral vein resulted in a dramatic reduction of pelvic venous reflux and resolution of symptoms. CONCLUSIONS: Recurrence of PCS can occur after ovarian vein embolization through other tributaries in the venous network. The median sacral vein is a rare cause of PCS. We present an interesting case of a successfully treated recurrent PCS with coil embolization of an incompetent median sacral vein.
