How often should males aged 65-75 who have smoked be screened for AAA?

Men aged 65 to 75 who have a history of smoking are recommended to undergo a one-time screening for abdominal aortic aneurysm (AAA). This recommendation arises from evidence indicating that this demographic is at an increased risk for developing AAA due to factors such as age and smoking history. Screening is vital because AAA can often be asymptomatic until they rupture, leading to severe complications or death.

Screening is not recommended to be performed every few years, nor is there a necessity for yearly screenings after the first one for this age group unless specific risk factors or symptoms emerge. Additionally, screening only when symptomatic may miss the opportunity for early detection in asymptomatic patients who could be at risk. Thus, a one-time screening provides a balance between identifying those at risk without subjecting all individuals to unnecessary repeated tests.
