Uterine Artery Embolization after Internal Iliac Artery Ligation

Abstract

Uterine artery embolization (UAE) is one of the primary therapies to treat symptomatic uterine fibroids. Even if the patient underwent internal iliac artery ligation during a massive pelvic hemorrhage or peripartum bleeding previously, UAE can be done through the collaterals for any other reasons.We report a 44-year-old woman who underwent UAE for symptomatic multiple uterine fibroids after internal iliac artery ligation with collaterals originating from the left external iliac artery. We briefly present the case's details and review collaterals pathways after left internal iliac artery ligation that might be encountered during UAE.
