Screening for abdominal aortic aneurysms in Western Australia

A study of ultrasound screening for abdominal aortic aneurysms (AAA) was performed. During a 6 month period, 1225 men and women aged 60-80 years were screen at a variety of community venues. Screening was well received by the public and logistically simple to perform. Thirty-three AAA were detected with sizes between 30 and 81 mm. In the 60-80 year age group, the prevalence of AAA > 30 mm in diameter was 4.7% in men and 0.35% in women, and the prevalence of AAA > 50 mm was 0.6% in men and 0.17% in women. Cigarette smoking, but not hypertension or diabetes, was found to be a significant risk factor for AAA. This study confirms that screening for AAA is feasible and yields high prevalence rates in major population centres.
