AAA ultrasound screening is recommended for which group?

• A. Annual ultrasound for men aged 65-75 who have ever smoked
• B. One-time abdominal ultrasound for men aged 60-70 who have ever smoked
• C. Start screening at 60 with ultrasound every 5 years
• D. One-time abdominal ultrasound for men aged 65-75 who have ever smoked

Answer: (D)

One-time abdominal ultrasound screening for abdominal aortic aneurysm is recommended for men aged 65 to 75 who have ever smoked. This group has a higher prevalence of AAA and a greater risk of rupture, and a single ultrasound can reliably detect aneurysms that may require monitoring or treatment. The USPSTF found that screening this population reduces AAA-related mortality, so a one-time test in this specific age and risk group is the most effective approach. It is not advised as an annual or ongoing program, and screening is not routinely recommended for men who have never smoked or for women based on current evidence. If an aneurysm is found, management depends on its size, with surveillance or referral for repair as appropriate.
