title: [Case report of post-traumatic arterial high-flow priapism].
abstract: Priapism is rare and usually unpredictable. High-flow priapism is caused by unregulated arterial inflow. Antecedent trauma is the most commonly described etiology. This condition does not require emergent treatment. The initial management of high-flow priapism should be observation, because treatment-related erectile dysfunction may appear. We report a case of high-flow priapism by perineal trauma in a 27-year-old man. His corpora were typically tumescent, but not completely rigid. He could not have sexual intercourse. Blood from the corpus cavernosum was normally oxygenated. Color duplex ultrasonography was performed in the lithotomy position, scanned at the perineum, showed pseudoaneurysmal appearance. Selective internal pudendal arteriography showed a right cavernous arterial extravasation. Superselective embolization of right internal pudendal arteries was performed with an autologous clot. After the procedure, detumescence was achieved as well as erectile function. We recommend superselective arterial embolization as the management of high flow priapism to patients who request treatment.
