Use of a nonmedical, catalogue type vacuum erection device resulted in a case of vacuum induced vasculogenic impotence and Peyronie's disease.
A 66-year-old potent man used a nonmedical vacuum erection device (cylinder plus a hand pump without a pressure-release valve and a doughnut-shaped ring at the base without tension bands) after having achieved a spontaneous rigid erection. The resultant excessive overinflation of the penis was followed by dorsal curvature, diminished rigidity and decreased erectile maintenance.
Physical examination revealed a dorsal mid shaft Peyronie's plaque. Nocturnal penile tumescence testing and office injection testing were abnormal and demonstrated partial, short-lived, dorsally curved erections. Dynamic pharmaco-cavernosometry and pharmaco-cavernosography established vasculogenic impotence with site-specific crural (unrelated to the Peyronie's plaque) veno-occlusive dysfunction and dorsal penile curvature.
Vacuum erection devices create pulling forces on the penis. We estimate that the pulling forces in this case were prohibitively high (approximately 29 pounds) due to absence of a pressure-release valve and to the preexistent erection at vacuum application. These intense pulling forces are hypothesized to have damaged the tunica in the mid shaft (Peyronie's disease) and the crus (veno-occlusive dysfunction), the latter being the site of attachment of the corpora to the ischiopubic ramus and a most likely location for high magnitude pulling forces to exert an abnormal injury effect. The patient underwent a Nesbit plication procedure and presently performs self-injection for satisfactory sexual activity.
使用非医用的目录型真空勃起装置导致了一例真空诱导的血管性阳痿和佩罗尼氏病。
一名66岁性功能正常的男性在自然勃起后使用了非医用真空勃起装置（圆筒加手动泵，无压力释放阀，底部有甜甜圈形环但无张力带）。阴茎过度充气后出现阴茎背曲、硬度降低和勃起维持时间缩短。
体格检查发现阴茎背侧中轴有佩罗尼氏斑块。夜间阴茎勃起试验和门诊注射试验均异常，显示为部分、短暂、背曲的勃起。动态药物海绵体测压和药物海绵体造影确定为血管性阳痿，伴有特定部位的阴茎脚（与佩罗尼氏斑块无关）静脉闭塞功能障碍和阴茎背曲。
真空勃起装置会对阴茎产生拉力。我们估计，由于没有压力释放阀以及在施加真空时已有勃起，该病例中的拉力过高（约29磅）。据推测，这些强大的拉力损伤了阴茎中轴的白膜（佩罗尼氏病）和阴茎脚（静脉闭塞功能障碍），后者是海绵体附着于耻骨坐骨支的部位，也是高拉力最可能产生异常损伤作用的位置。该患者接受了内斯比特折叠手术，目前通过自我注射来进行满意的性活动。
