Vascular origin accounts for more than 25% of cases of disturbances of erection. Venous pathology may explain the majority of erectile dysfunctions in patients with normal arterial anatomy. We have performed cavernography in 115 patients with monitoring of intracavernous pressure. Nocturnal plethysmography was recorded in all cases to prove the organic etiology of the erectile dysfunction. Cavernography was realized after puncture of both corpora cavernosa by two microcatheters (19-21 G). The intracavernous pressure was recorded through 1 of them and the contrast medium infused through the other. The contrast medium is infused at a rate of 80-120 ml/min. until the penis appears erect. The simultaneous recording of the intracavernous pressure then showed a rapid increase of the pressure curve followed by a stabilization at greater than or equal to 90 mHg. The flow to maintain the erection reach 1/3 of the flow needed to induce the erection. The venous leak is characterized by the absence of erection, no increase in intracavernous pressure and a rapid opacification of the vein. Artificial erection induced in impotent men allows to classify patients with vascular organic impotence into three categories: those with pure arterial insufficiency, those with pure venous leak, and patients with both.
血管源性因素占勃起功能障碍病例的25%以上。静脉病变可能是动脉解剖结构正常的患者中大多数勃起功能障碍的原因。我们对115例患者进行了海绵体造影,并监测海绵体内压力。所有病例均记录夜间阴茎体积描记图,以证实勃起功能障碍的器质性病因。通过两根微导管(19 - 21G)穿刺双侧海绵体后进行海绵体造影。通过其中一根导管记录海绵体内压力,通过另一根导管注入造影剂。造影剂以80 - 120 ml/min的速度注入,直到阴茎勃起。随后同时记录海绵体内压力,显示压力曲线迅速上升,随后稳定在大于或等于90 mmHg。维持勃起所需的血流量达到诱发勃起所需血流量的1/3。静脉漏的特征是无勃起、海绵体内压力无升高以及静脉迅速显影。对阳痿患者进行人工勃起可将血管性器质性阳痿患者分为三类:单纯动脉供血不足者、单纯静脉漏者以及两者皆有的患者。
