Abdominal aortic aneurysms (AAAs) represent a potentially life-threatening condition that occurs in up to 10 percent of the aged populations in industrialized nations.
An aneurysm is broadly defined as a permanent localized dilatation of an artery.
AAAs arise due to substantial remodeling of the extracellular matrix and are frequently accompanied by atherosclerosis. They may be manifested by catastrophic rupture, signs of pressure on other viscera or an embolism originating in the aneurysm wall, but most are asymptomatic. AAA is correlated to atherosclerosis.
