Priapism is a prolonged penile erection not associated with sexual arousal. Two types of priapism have been described: the more common one is the "veno-occlusive" priapism and can be frequently observed as the consequence of an intracavernosal
injection of vaso-active drugs for the treatment of erectile dysfunction. The less common type of priapism is known as "high flow" priapism. The most frequent cause of high-flow priapism is penile or perineal closed trauma with laceration of the
cavernous artery and the formation of an arterial-lacunar fistula. We present a 23 year old male with high-flow priapism due to closed perineal trauma and damage to the right cavernous artery which was completely resolved following super-selective angiography and embolization treatment
