Surgery (open or endovascular) is the definitive treatment of an aortic aneurysm. Medical therapy is typically reserved for smaller aneurysms or for elderly, frail patients where the risks of surgical repair exceed the risks of non-operative therapy (observation alone).
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.

An aortic aneurysm often doesn’t cause symptoms, but it can lead to severe, sudden bleeding from a ruptured aneurysm. A ruptured aneurysm has a high risk of death. If symptoms of an aortic ...

An aortic aneurysm increases risk of dissection, as do family history and certain genetic syndromes. Triggers. Injury to the chest, extreme strain on the body, drug use and high blood pressure can ...
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."
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 ]
