PBI was measured in 555 patients chosen at random from those who visited our impotence clinic between October 1984 and September 1986. Of 555 patients with impotence 29 (5.2%) showed a low PBI level of less than 0.6. On the basis of carefully taken history, risk factors causing the disturbance of penile blood flow were found in 13 (44.8%) of these 29 patients. They included diabetes mellitus, hypertension, surgery of pelvic organ, vertebral injury, vascular disorder of brain and gangliosympathectomy. Although penile angiography is necessary to make the definite diagnosis of vasculogenic impotence, hospitalization is usually required to perform the examination. Measurement of PBI is useful as a screening test to detect vasculogenic impotence at an outpatient clinic, because this examination is noninvasive and technically easy.
对1984年10月至1986年9月间前来我院阳痿门诊就诊的患者随机抽取555例进行阴茎肱动脉指数（PBI）测定。555例阳痿患者中，29例（5.2%）PBI水平低于0.6，处于较低水平。根据详细的病史记录，在这29例患者中有13例（44.8%）发现了导致阴茎血流障碍的危险因素。这些因素包括糖尿病、高血压、盆腔器官手术、脊椎损伤、脑血管疾病和神经节交感神经切除术。虽然阴茎血管造影对于明确血管性阳痿的诊断是必要的，但通常需要住院进行该项检查。PBI测定作为一种筛查试验，对于在门诊检测血管性阳痿是有用的，因为这项检查是非侵入性的，且技术操作简便。
