Patients present with severe vaginal bleeding which usually does not respond to conservative management and on most of occasions requires radiological or surgical intervention. We report a case of acquired AVM in a ruptured caesarean section scar. The patient presented with life-threatening vaginal bleeding and was treated with gonadotropin releasing hormone agonist and subsequent angioembolisation coiling.
