Cavernous artery obstruction following blunt trauma to the penis.

Abstract

Erectile dysfunction following blunt trauma to the erect penis usually is associated with an injury to the tunica albuginea of the corpus cavernosum. We recently identified 2 patients with erectile dysfunction following bending of the penis during coitus whose only abnormality after a complete evaluation, including penile angiography, was a deep cavernous artery injury. We suggest that during examination of patients with erectile dysfunction following blunt injury to the erect penis a complete vascular evaluation, including penile angiography, may be necessary to detect an unrecognized injury to the deep cavernous arteries.
