Use of selective embolization of the bilateral cavernous arteries for posttraumatic arterial priapism.

Nonischemic arterial high flow priapism caused by traumatic laceration of a branch of the penile cavernous artery is rare. We report a case of laceration of the left and right branches of the intracavernous artery, which was confirmed by selective internal pudendal arteriography. Bilateral cavernous artery embolization was performed using gelatin sponge and detumescence occurred immediately. Normal potency was evident 4 months later. Our case demonstrates that selective cavernous arterial embolization is a safe and effective therapy for arterial priapism and that erectile function can return to normal.

Pulmonary artery involvement in aorto-arteritis. An analysis of DSA.

Angiographic features of the pulmonary artery were studied in 24 patients with aortoarteritis (Takayasu's arteritis) by digital subtraction angiography. The pulmonary artery involvement was found in nine cases (37.5%). The right side was involved in eight and the left side in five cases. The right pulmonary artery was involved in two cases, the lobar artery in six, the segmental artery in six, and subsegmental as well as peripheral branches in four. The angiographic features were stenosis and/or occlusion as were the changes of the systemic arteries in aorto-arteritis. The aorta and its main branches were involved in all nine patients, but the severity of pulmonary vascular changes was not always related to the systemic vascular changes. Bronchial angiography demonstrated enlarged and tortuous bronchial arteries in four cases. Lung ECT revealed abnormalities in four cases.
