Who should receive a one-time ultrasound screening for AAA?

A one-time ultrasound screening for abdominal aortic aneurysm (AAA) is specifically recommended for men aged 65-75 who have a history of smoking. This population is at a significantly higher risk for developing AAA due to the known impact of smoking on vascular health and the increased incidence of aneurysms in this demographic group.

The rationale behind focusing on men within this age range and smoking history stems from epidemiological studies indicating that men are more likely to present with AAA than women, and that smoking is a major risk factor that further elevates the likelihood of aneurysms developing or rupturing. Therefore, the screening is a preventive measure aimed at detecting any aneurysms early, before they can lead to serious health complications.

While screening guidelines may suggest various recommendations for different groups, only men aged 65-75 who have smoked are included in this specific guideline for a one-time ultrasound screening for AAA. This targeted approach maximizes resource use and ensures that individuals at the highest risk receive appropriate surveillance.
