High prevalence of abdominal aortic aneurysm in men with peripheral vascular disease: Screening by ultrasonography

Abstract

Abstract 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 percent. 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.
