Transcatheter embolization of uterine arteriovenous malformation: report of 2 cases and review of literature

Abstract

Arteriovenous malformation (AVM) of the uterus is a rare cause of menorrhagia and may at times lead to life-threatening hemorrhage. The clinical findings may not always be reliable in the diagnosis of uterine AVM, and a high index of suspicion is important because, unlike many other causes of menorrhagia, curettage may paradoxically aggravate the bleeding. Herein are described the cases of 2 patients with uterine AVM with abnormal vaginal bleeding. Both had a history of abortion followed by dilation and curettage. In both patients, the diagnosis of uterine AVM was established at Doppler flow ultrasonography. Treatment using transcatheter embolization was successful, and both patients had normal menstrual cycles at follow-up. One patient delivered a healthy baby 2½ years after transcatheter embolization.
