Impotence due to corporeal veno-occlusive dysfunction: long-term follow-up of venous surgery.
Corporeal veno-occlusive dysfunction is an important cause of organic impotence and is characterized by increased flow rates to create and to maintain erection during artificial erection produced by intracavernous saline infusion. Sixty-seven patients with this erectile insufficiency underwent penile ligature-resection of deep dorsal vein between 1982 and 1986, and were evaluated by nocturnal plethysmography, pharmacocavernometry as well as a questionnaire about their sexual life for long-term follow-up. The surgical procedure was controlled in the operating room by reduction of the erectile flow rates. Thirty-one patients were potent postoperatively and were able to have satisfactory intercourse. Results after resection were slightly better than after simple ligation of the deep dorsal vein. Four patients had penile glans insensibility resulting from the surgical dissection. There were 7 relapses several months after the procedure due to leakage through other deeper veins. Eight failures were due to additional psychogenic disorders or to neurologic disease not accurately diagnosed before the treatment because they all developed normal papaverine-induced erection after venous surgery while before it they only developed a slight tumescence. Reduction of the erectile flow rates within normal values was impossible during surgery in 3 patients. Eleven failures were due to concomitant arterial disease. Resection of the deep dorsal vein can restore penile erection in patients with cavernovenous leakage in about 50% of well-selected patients.
