A Case of Uterine Arteriovenous Malformation: Ultrasound Appearance.
Rebecca Chambers, Manchester Fertlility
Introduction
Uterine arteriovenous malformation (UAVM) is a rare gynaecological condition which can be life threatening when presenting with severe vaginal bleeding. Arteriove-nous malformations are abnormal communications between arteries and veins in a tissue without the presence of an intervening capillary network. They are classified as congenital or acquired. Congenital type UAVM is very rare, and it results from developmental abnormalities of uterine vessels. Acquired type is more common, and may develop after: multiple pregnancies, miscarriage, previous surgery, dilation and curettage (D&C), termination of pregnancy and caesarean section. Management of UAVM depends on clinical presentation. Most of the time UAVMs will resolve spontaneously; however, they may require treatment such as uterine artery embolization hysterectomy (Yoon et al., 2016).
