Priapism has been classified as primary (idiopathic) and secondary according to etiology. Hemodynamically, it can be separated into two distinct types: low-flow (ischemic) and high flow (non-ischemic). In the latter type, the most common cause is blunt genital trauma, and selective cavernosal artery embolization has been the most effective therapeutic method. Two cases of high-flow arterial priapism are presented. Both cases were post-traumatic and were managed with selective cavernosal artery embolization, with excellent retum of premorbid levels of erectile function.
