They have a natural history characterized by progressive expansion and eventual rupture.1 Population-based screening studies reveal that up to 9 percent of persons over 65 years of age have an unsuspected and asymptomatic abdominal aortic aneurysm, and it is estimated that ruptured abdominal aortic aneurysms cause at least 15,000 deaths each year in the United States.2 The principal goal of treatment for these aneurysms is to extend life by preventing the rupture of the aneurysm.
