Authors' objectives:

While the prognosis for abdominal aortic aneurysm (AAA) rupture is poor, ultrasound imaging is an accurate and reliable test for detecting AAAs before rupture. This study aims to examine the benefits and harms of population-based AAA screening.

Authors' results and conclusions: We identified four population-based randomized controlled trials of AAA screening in men 65 years and older. Based on meta-analysis, an invitation to attend screening was associated with a significant reduction in AAA-related mortality (OR 0.57; 95% CI, 0.45 to 0.74). A meta-analysis of three trials revealed no significant difference in all-cause mortality (OR 0.98; 95% CI, 0.95 to 1.02). No significant reduction in AAA-related mortality was found in one study of AAA screening in women. Screening does not appear to be associated with significant physical or psychological harms. For 4.0-5.4 cm AAAs, immediate surgical repair, compared to surveillance with delayed repair, does not appear to improve either AAA-related mortality or all-cause mortality. Major treatment harms include 2 to 6% operative mortality rate and significant risk of major complications.

Authors' recommendations: For men age 65 years and older, an invitation to attend AAA screening reduces AAA-related mortality.
