Bilateral superselective arterial microcoil embolisation in delayed post-traumatic high flow priapism.

High flow arteriogenic priapism is uncommon and usually occurs after trauma to the genitoperineal area. The onset of prolonged erection can be delayed and is often relatively pain free. Arteriography in this case illustrated the causative bilateral arteriocavernosal fistulae and pseudoaneurysms. Treatment consisted of staged bilateral superselective metallic microcoil embolisations, resulting in prompt detumescence. There were no complications. The patient had normal erectile function six months later. Recent concerns about erectile dysfunction with the bilateral use of permanent metallic coils appear to be unfounded.
