A study was carried out to see if an ultrasonic examination of the abdominal aorta was indicated in every patient who attended an outpatient clinic with peripheral vascular disease (PVD). One hundred consecutive patients were studied and compared with a control group. The incidence of abdominal aortic aneurysm (AAA) in the control group was 2 per cent. In the study group, the male patients had an incidence of 20 per cent of aneurysm and ectasia, while the female patients had an incidence of 12 per cent. Of all the abnormal aortas found by ultrasound, only 31 per cent were palpable clinically. Two aneurysms that required operation were found, while the remainder are to be followed by regular ultrasound assessment. Further studies are necessary to conclude if screening of a high risk group, such as patients with PVD, is worthwhile.
开展了一项研究，以确定对于每一位因外周血管疾病（PVD）前来门诊就诊的患者，是否都需要进行腹主动脉超声检查。对连续100例患者进行了研究，并与一个对照组进行比较。对照组腹主动脉瘤（AAA）的发生率为2%。在研究组中，男性患者动脉瘤和扩张的发生率为20%，而女性患者的发生率为12%。在超声检查发现的所有异常主动脉中，临床上仅31%可触及。发现了2例需要手术的动脉瘤，其余的则需通过定期超声评估进行随访。是否值得对PVD患者等高风险群体进行筛查，还需要进一步研究才能得出结论。
