Spontaneous Resolution of Traumatic AV Malformation of the Uterus Following Hysteroscopic Cold Knife Evacuation of Retained Products of Conception

Uterine myometrial arteriovenous malformations (AVM) are reported on color doppler ultrasonography as mosaic pattern of blood flow with different peak systolic velocities (PSV) at different places. High PSV within the AVM may require arterial embolization as treatment. However, we present a case of traumatic AVM with incomplete abortion managed by hysteroscopic cold knife evacuation. This case report is of a young patient with off and on vaginal bleeding for 3 1/2 months following 2nd trimester spontaneous abortion. She had undergone dilation and evacuation (D & E) for incomplete abortion. Now the bleeding was heavy and intermittent not responding to medications. The subsequent TVS examination shows incomplete abortion with myometrial AVM with high PSV. Hysteroscopic cold knife removal of products of conception resulted in immediate resolution of Uterine AVM.
