Post-traumatic, high-flow priapism treated with selective cavernous artery embolization and intracavernous streptokinase irrigation: a case report.

A 54-year-old man developed priapism shortly after a blunt perineal trauma. An arteriocavernous fistula caused the high-flow priapism, and was detected on both color Doppler sonography and selective phaloarteriography. Selective embolization of the left cavernous artery with Gelfoam was performed to seal the fistula, resulting in immediate detumescence. However, the penis remained firm despite returning to almost normal size. No fistula was detected by subsequent color Doppler sonography and phaloarteriography examination. Intracavernous irrigation with 200,000 U streptokinase was applied to treat residual firmness 2 weeks after embolization. Successful sexual intercourse was reported 3 months later. The combination of selective cavernous artery embolization and intracavernous streptokinase irrigation was effective for the treatment of the high-flow priapism in this case.
