Uterine arteriovenous malformation secondary to scar pregnancy

Abstract

Uterine arteriovenous(AV) malformations resulting in abnormal uterine bleeding is relatively rare condition. It can be congenital or acquired. Acquired AV malformation is usually secondary to trauma, pregnancy or malignancy. The mainstay of management is uterine artery embolization or definitive surgery. We report a case of AV malformation in lower uterine segment secondary to previous ruptured scar pregnancy. The condition was diagnosed by Doppler ultrasound and confirmed by MR angiography. Our subject opted for hysterectomy over uterine artery embolization. The clinical findings were confirmed by histopathological examination by presence chorionic villi.
