Background Aneurysm of the abdominal aorta is common in older men. An aortic diameter of 30 millimeters, or more, is defined as an abdominal aortic aneurysm. As an aneurysm becomes larger the risk for rupture increases, often with fatal consequences. Screening to detect the condition at an early stage is one approach toward reducing mortality from abdominal aortic aneurysm.

Conclusions

• Screening for abdominal aortic aneurysm leads to reduced mortality related to abdominal aortic aneurysm in men.The method is cost-effective.
• Scientific evidence is insufficient as regards the effects of screening for abdominal aortic aneurysm in women.
• Screening for abdominal aortic aneurysm is ethically defensible, provided that the screening programs are designed to satisfy fundamental ethical principles and that the information given in conjunction with the initial examination and follow up is objective and easily understood.
