Twenty men with incomplete penile erection or inability to maintain an erection were evaluated to determine if venous leakage was a cause. Cavernosography was performed in conjunction with artificial erection induced by infusion of saline into the corpus cavernosa. Thirteen patients requiring higher than normal rates of saline infusion to achieve or maintain erection showed filling of superficial veins in the flaccid state as well as during erection. In five of the seven patients with normal saline requirements there was no filling of superficial veins, and two showed filling in the flaccid state only. Of the thirteen patients whose conditions were diagnosed as venous leakage, seven underwent surgical ligation of superficial veins and deep penile vein arterialization by a saphenous vein bypass graft between the superficial femoral artery and deep penile vein. All these patients had reduced saline requirements postoperatively. When cavernosography is performed in the flaccid state only, filling of superficial veins can occur normally; therefore, these studies should be performed with artificial erection.
对20名阴茎勃起不完全或无法维持勃起的男性进行评估，以确定静脉漏是否为病因。在向海绵体注入生理盐水诱导人工勃起的同时进行海绵体造影。13名需要高于正常速率的生理盐水注入才能达到或维持勃起的患者，在疲软状态以及勃起过程中均显示浅表静脉充盈。在7名生理盐水需求量正常的患者中，有5名浅表静脉无充盈，2名仅在疲软状态下有充盈。在被诊断为静脉漏的13名患者中，7名接受了浅表静脉手术结扎，并通过大隐静脉旁路移植术在股浅动脉和阴茎深静脉之间进行阴茎深静脉动脉化。所有这些患者术后生理盐水需求量均减少。仅在疲软状态下进行海绵体造影时，浅表静脉可能正常充盈；因此，这些研究应在人工勃起状态下进行。
