RESUMO
We report a case of priapism secondary to bilateral rupture of the cavernosal arteries following perineal blunt trauma in a 34 year old man. He complained of painless but persistent erection for the period of 1 week. We confirmed non-ischemic high-flow priapism by arterial blood gas analysis, Doppler ultrasonography and arteriography. Arteriography showed a leakage on both sides of the end of the cavernosal arteries and the leakage was blocked by superselective cavernosal artery embolization. After the embolization, tumescence began to disappear and the detumescence process was completed on the third day. The examination of the patient after 4 months following embolization revealed that the patient was fully free of priapism and returned to the normal erectile status like before his priapism. During 2 years of follow up, the patient had no complications such as priapism or impotence.
