CHRONIC PRIAPISM SECONDARY TO A TRAUMATIC ARTERIOVENOUS-FISTULA OF THE CORPUS CAVERNOSUM

A 30-year-old man presented with a 7-month history of chronic partial priapism and sexual dysfunction following blunt perineal trauma. Duple x penile ultrasound confirmed high flow priapism and color flow Dopple r ultrasound diagnosed an arteriovenous fistula within the left corpus cavernosum. This lesion was corrected via corporeal exploration and l igation of the artery feeding the fistula. The use of color flow Doppl er ultrasound to diagnose this unusual condition obviated the need for angiographic studies. This rare condition of posttraumatic priapism m ay be diagnosed by noninvasive means. The pathophysiology, diagnosis a nd treatment of posttraumatic priapism and review of the literature ar e discussed.
