Embolization of a traumatic uterine arteriovenous malformation.

Uterine arteriovenous malformation (AVM) is a rare but potentially life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manor are essential because instrumentation that is often used for other sources of uterine bleeding can lead to massive hemorrhage. Although angiography remains the gold standard for diagnosis, ultrasound (US) and magnetic resonance imaging (MRI) are the modalities of choice for the evaluation of a suspected AVM.
