Treatment of posttraumatic chronic high-flow priapisms by superselective embolization of cavernous artery with autologous clot.

Two cases of high-flow priapism that occurred after blunt perineal trauma and lasted for 35 days (case 1) and 40 days (case 2) were successfully treated by embolization of the lacerated cavernous arteries with autologous clots. Cavernous arterial blushes were demonstrated on selective internal pudendal arteriograms in both cases. Case 1 with left cavernous arterial laceration restored 80% of premorbid erectile function with successful intercourse 4 months after superselective embolization. In case 2 with bilateral cavernous arterial lacerations, premorbid erectile function was fully resumed 2 months after bilateral embolization of the cavernous arteries at intervals of 15 days. None developed local or systemic complications.
