Use of selective embolization of the bilateral cavernous arteries for posttraumatic arterial priapism.

Nonischemic arterial high flow priapism caused by traumatic laceration of a branch of the penile cavernous artery is rare. We report a case of laceration of the left and right branches of the intracavernous artery, which was confirmed by selective internal pudendal arteriography. Bilateral cavernous artery embolization was performed using gelatin sponge and detumescence occurred immediately. Normal potency was evident 4 months later. Our case demonstrates that selective cavernous arterial embolization is a safe and effective therapy for arterial priapism and that erectile function can return to normal.
