Uterine arteriovenous malformations: a review of the current literature

Uterine arteriovenous malformation (AVM) is a rare but potentially life-threatening condition. AVMs often present with intractable bleeding and commonly are seen in association with pregnancy and uterine trauma. Ultrasound is the most common form of initial investigation, and computed tomography and magnetic resonance imaging are being used with greater frequency. Despite this, angiography remains the gold standard for diagnostic evaluation. Embolization has become a more acceptable form of treatment and allows more invasive forms of treatment, particularly hysterectomy, to be avoided. Numerous medical therapies have also been used in the management of patients with uterine AVM. Reports of successful pregnancies after diagnosis and treatment of a uterine AVM are still uncommon, but increasingly good outcomes are being reported after successful treatment of a confirmed uterine AVM.
