Aneurysmal degeneration can occur anywhere in the human aorta; most aortic aneurysms (AAs) occur in the abdominal aorta and thus are termed abdominal aortic aneurysms (AAAs). An abdominal aortic aneurysm (AAA) occurs in the part of the aorta which lies in the abdomen, below the kidneys, and is by far the more common type of aneurysm, accounting for approximately 75% of all cases and affecting 1.5% of men aged 65 or older.

Variable induction of experimental abdominal aortic aneurysms with different preparations of porcine pancreatic elastase. A true aneurysm involves all three layers of the vessel, whereas pseudoaneurysm is characterized by disruption of the intima and media, and the dilated segment of the aorta is lined by adventitia alone. Doctors don't really know what causes an abdominal aortic aneurysm, although they suspect a few things might play a role: Hardening of the arteries, which doctors also call atherosclerosis; Perioperative mortality of traditional open AAA repair ranges from 1 to 4%. Inflammatory cells are thought to degrade structural proteins (such as elastin) in the wall of the aorta, weakening it and allowing for aneurysm formation.

Diagnosis 1. they become too large and rupture, or burst. dissecting thoracic aortic aneurysm. Rupture risk of AAA increases with increasing aortic diameter and this catastrophic event is associated with a mortality of 50 - 80%. High blood pressure, which is the leading risk factor for thoracic aortic aneurysms but also a risk factor for abdominal aortic aneurysm. Chapter 37. Finding an aortic aneurysm before it ruptures offers your best chance of recovery. The most widely accepted is that aaas form due to an inflammatory process in the wall of the aorta associated with atherosclerosis.
