Abstract
Screening for abdominal aortic aneurysm (AAA) saves lives. It can be carried out successfully in large communities and across the population of whole countries. It is a cost-effective strategy when applied to men aged 65 years who are, or have been, smokers, even with the falling prevalence of AAA at age 65 years in men from 4 per cent down to 1ยท1 per cent. Wider implementation would seem inevitable, based on excellent models in the UK and Sweden.
