Uterine arteriovenous malformations can be congenital or acquired. The acquired form results from arteriovenous anomalies in which one or more uterine arteries and venous plexuses from the endometrium and/or myometrium communicate without the interposition of a vascular nest. It is composed of tortuous arteriovenous shunts, fragile and with low resistance. It is a rare but serious pathology that can threaten the patients prognosis. The therapeutic strategy is determined by the symptoms, the desire for subsequent pregnancy, the extension and the location of the malformation. The two main types of treatment are selective embolization and hysterectomy. We report a new case of postpartum arteriovenous malformation treated by hysterectomy after failure of conservative treatment by ligation of the internal iliac arteries. The anatomopathological examination of the hysterectomy specimen confirmed the diagnosis of AVM.
