Synopsis

Focal dilation of the abdominal aorta, most commonly infrarenal in location but with 15% juxtarenal in location. Risk factors for development of abdominal aortic aneurysm (AAA) include smoking, advancing age, previous aneurysm, atherosclerotic disease, or a family history of AAA as well as being of Northern European descent and male.

At the time of diagnosis, most patients are asymptomatic, but those with symptoms typically have abdominal pain, back pain, or evidence of lower extremity ischemia. Physical exam findings may include a pulsatile abdominal mass.
