Repair of asymptomatic abdominal aortic aneurysms is recommended when the risk of rupture exceeds the risk of repair. Randomized controlled trials have failed to show a survival benefit for open or endovascular repair of most small aneurysms. Repair may be considered with specific growth patterns and aneurysm morphology.
