Relatively rare high-flow priapism is most frequently caused by contusion or direct injury of the cavernous artery with a subsequent uncontrolled inflow of arterial blood into the cavernous bodies. Knowledge of this pathophysiology and the development of intervention radiology made a more selective therapeutic approach possible. The authors present a report on a case of arterial or high-flow priapism which was successfully resolved by a minimally invasive approach--percutaneous superselective transcatheter embolization of the internal pudendal artery.
