Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal. [1] An AAA usually causes no symptoms, except during rupture. [ 1 ]
One review stated that up to 81% of people having abdominal aortic aneurysm rupture will die, with 32% dying before reaching a hospital. [ 6 ] According to a review of global data through 2019, the prevalence of abdominal aortic aneurysm worldwide was about 0.9% in people under age 79 years, and is about four times higher in men than in women ...
Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair."
Similar to AAA, IAA occurs in the abdominal region. [1] IAA is closely associated and believed to be a response to and extensive peri-aneurysmal fibrosis, [ 2 ] which is the formation of excess fibrous connective tissue in an organ or tissue in a reparative or reactive process IAA accounts for 5-10% of aortic aneurysms.
Prior to the advent of endovascular aneurysm repair (EVAR), OAS was the only surgical treatment available for aortic aneurysms. The shift away from open aortic surgery towards endovascular surgery since 2003 has been driven by worse perioperative mortality associated with OAS, particularly in patients in relatively frail health.

The Infrarenal segment, ... A transverse contrast enhanced CT scan demonstrating an abdominal aortic aneurysm of 4.8 by 3.8 cm.
An abdominal aortic aneurysm (AAA) refers to aneurysmal dilation of the aorta confined to the abdominal cavity. Most commonly, aneurysms are asymptomatic and located in the infrarenal position. Often, they are discovered incidentally or on screening exams in patients with risk factors such as a history of smoking.
Annuloaortic ectasia is characterized by pure aortic valve regurgitation and aneurysmal dilatation of the ascending aorta. [2] Men are more likely than women to develop idiopathic annuloaortic ectasia, which usually manifests in the fourth or sixth decades of life.
