One hundred twenty patients aged fifty years and over underwent screening by ultrasound for abdominal aortic aneurysms as part of their routine follow-up visit to a cardiologist. The overall incidence of aneurysm greater than or equal to 4 centimeters in diameter was 5%. In the 84 men with aortas less than 4 centimeters, the average aorta size was 2.4 centimeters. In the 30 women with aortas less than 4 centimeters, the average aorta size was significantly smaller, 1.9 centimeters (p less than .001). It was discovered that men who smoke and have hypertension have a statistically significant increase in aorta size compared to those men without these risk factors (less than .05). The results indicate that the incidence of abdominal aortic aneurysm is probably high enough in this population to justify screening by ultrasound.
120名年龄在50岁及以上的患者在心脏病专家的常规随访中接受了腹部主动脉瘤的超声筛查。直径大于或等于4厘米的动脉瘤总体发病率为5%。在84名主动脉直径小于4厘米的男性中，平均主动脉大小为2.4厘米。在30名主动脉直径小于4厘米的女性中，平均主动脉大小明显更小，为1.9厘米（p小于0.001）。研究发现，与没有这些危险因素的男性相比，吸烟且患有高血压的男性主动脉大小在统计学上有显著增加（小于0.05）。结果表明，该人群中腹主动脉瘤的发病率可能高到足以证明通过超声进行筛查是合理的。
