The long-term follow-up of the Western Australian trial of screening for abdominal aortic aneurysms (AAAs) reported in this issue of JAMA Internal Medicine1 is likely the last report from the 4 randomized clinical trials1-4 of AAA screening and the end of an era that began with the Chichester, United Kingdom, trial2 in 1989. Earlier combined results from the 4 trials found that screening with ultrasonography reduced AAA-related mortality in older men by more than 40% and led to the 2005 recommendation by the US Preventive Services Task Force (USPSTF) for 1-time ultrasonographic screening for AAAs in men 65 to 75 years old who have ever smoked. Since then, a meta-analysis5 that incorporated longer follow-up from these trials has strengthened the case for screening, revealing increasing benefit and cost-effectiveness.
