Arteriovenous malformation of the uterus associated with secondary postpartum hemorrhage.

We present the case of a young woman with persistent secondary postpartum hemorrhage. Transvaginal imaging demonstrated an irregular pulsatile lesion in the anterior myometrium. Color Doppler analysis revealed the presence of abnormal vessels consistent with an arteriovenous malformation. Typically this vascular abnormality had a turbulent pattern of arterial and venous flow with high peak velocities and low resistance. The patient was treated with selective arterial embolization leading to a full recovery. Copyright 2003 ISUOG. Published by John Wiley & Sons, Ltd.
