The USPSTF recommends 1-time screening with ultrasonography in which group?

• A. Men aged 65-75 who have ever smoked
• B. Women aged 65-75 who have ever smoked
• C. Men aged 65-75 who have never smoked
• D. All adults over 50

Answer: (A)

Screening for abdominal aortic aneurysm (AAA) with a one-time abdominal ultrasound is recommended for men aged 65 to 75 who have ever smoked. This group has the highest prevalence of AAA, and detecting aneurysms before rupture allows elective repair that significantly reduces AAA-related mortality, making the test cost-effective and beneficial in this population. In contrast, routine screening in women or in men who have never smoked has not shown the same clear mortality benefit, and screening all adults over 50 would include many low-risk individuals, reducing the overall balance of benefits to harms.
