Between March 1991 and April 1993, 1188 subjects aged 65-75 years, out of 2734 invited, underwent abdominal ultrasound for screening of asymptomatic abdominal aortic aneurysms (AAA). For each patient the maximal anteroposterior and transverse diameters of the suprarenal and infrarenal aorta were measured. According to the literature data an AAA is defined as an aortic dilatation > 29 mm. AAA <40 mm are followed by ultrasound every 6 months and the AAA > 39 mm are considered for surgical repair after complete clinical work-up. In addition any aortic dilatation ranging 26-29 mm is followed too, using the same criteria. The aorta was normal in 1112 patients (95.12%), an infrarenal aortic dilatation was found in 21 patients (1.79%), an AAA <40 mm in 15 patients (1.28%) and an AAA > 39 mm in 21 patients (1.79%). The global prevalence of AAA > 29 mm was 3.07% (0.3% for the females and 6.8% for the males), similar to that reported by other authors. The statistically significant (p <0.01) risk factors were: smoking, alcohol consumption, coronary disease and chronic lung obstruction. Hypertension and dyslipidaemia were not significant (but HDL-cholesterol and Apo-B), according to a different etiology of the aneurysms. In addition 38.5% of the patients had total cholesterol > 240 mg/dl but only 34.9% of these was under medical treatment and/or on a diet. Our preliminary data confirm the results of similar studies in other countries: screening for AAA is worthwhile on the general population and, looking to a better cost-benefit rate, it might be focused only on males.
