Screening for abdominal aortic aneurysm in asymptomatic adults

Population-based screening for AAA with ultrasound scan in asymptomatic men aged 65 years and older showed statistically significant reductions in AAA-related mortality and rupture and, hence, avoids unnecessary AAA-related deaths. The current evidence showed no benefit of one-time AAA screening in woman. Limited evidence is available on the benefits of repeat AAA screening and targeted screening approaches based on risk factors for AAA. Future research should explore the differential benefits of AAA screening based on risk factors that increase risk for developing AAA.
