Priapismo arterial de alto flujo secundario a fístula arterio-cavernosa bilateral post-traumática: Embolización supraselectiva con coágulo autólogo

high flow arterial priapism is rare and characterized to a prolonged non-painful partial erection. arteriocavernous fistula, rarely bilateral, is associated with penile or perineal trauma (genitoperineal area). review of the literature, in only eleven cases this fistula is bilateral. diferents treatments with non common norm has been used. we report a case of a 27 years old male who presented high folw priapism secondary to bilateral postraumatic arterio-cavernous fistula. autologous blood clot was used for fistulas embolization to minimize the risk of impotence in this young patient. no complications was registered. eight months later the patient had normal erectile function and no fistula was detected on ultrasonography doppler. we consider arteriography with highly selective embolization using reabsorbable agents obtains the best results, the least risks and complications in this process.
