Task Force evidence reviews suggests that one-time screening for abdominal aortic aneurysms could benefit older men

A one-time screening for abdominal aortic aneurysm in men 65 years or older is associated with decreased AAA rupture and AAA-related mortality rates, according to a new review being published in Annals of Internal Medicine. AAA is a weakening in the wall of the infrarenal aorta resulting in localized dilation, or ballooning, of the abdominal aorta. A large proportion of AAAs are asymptomatic until a rupture develops, which is generally acute and often fatal (up to 83 percent of patients die before hospitalization).
