Cavernosography following clinical failure of penile vein ligation for erectile dysfunction

In an attempt to determine what occurs to the venous circulation of the penis after ligation of the deep dorsal vein, 9 men with veno-occlusive dysfunction who underwent deep dorsal penile vein ligation and failed to achieve normal erectile function postoperatively consented to a postoperative cavernosogram. Preoperatively, the deep dorsal vein was visualized in all 9 patients, the cavernous vein in 2 and the corpus spongiosum in 1. Postoperatively, the deep dorsal vein was visualized in 1 patient, the cavernous vein in 1 and the corpus spongiosum in 8. These observations suggest that either the inability to identify a cavernous-spongiosal communication preoperatively or the induction of such a communication postoperatively may lead to a clinical failure in patients who undergo deep dorsal penile vein ligation.
