Abstract
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.
