This chapter, found in the abdominal and pelvic pain section of the book, provides a succinct synopsis of a key study examining the use of ultrasound for screening asymptomatic patients for abdominal aortic aneurysms (AAAs). This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. The study showed that screening for AAAs can decrease aneurysm-related mortality rates. However, since AAAs contribute to less than 3% of all deaths, screening provides no significant decrease in all-cause mortality. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.
