Successful bilateral uterine artery embolization during an ongoing pregnancy.

BACKGROUND Uterine arteriovenous malformations are rare, potentially life-threatening, vascular anomalies. CASE We report a case of a large arteriovenous malformation diagnosed during pregnancy that was successfully treated with bilateral uterine artery embolization at 20 weeks of gestation during an ongoing pregnancy. The procedure was uncomplicated, did not result in any fetal heart-rate changes, and, at 35 weeks of gestation, a liveborn male neonate was delivered through repeat cesarean without complications. Both the patient and her son are doing well more than 2 years after the procedure. CONCLUSION Uterine artery embolization during an ongoing pregnancy did not result in acute complications to the fetus or mother.
