Two modes of repair are available for an AAA: open aneurysm repair, and endovascular aneurysm repair . An intervention is often recommended if the aneurysm grows more than 1 cm per year or it is bigger than 5.5 cm. [52] Repair is also indicated for symptomatic aneurysms. Ten years after open AAA repair, the overall survival rate was 59%. [53]
Recently, there is some evidence VSARR has superior survival rates at 10 and 15 years along with reduced early mortality. [11] Moreover, while there is a decreased reoperation rate in the first 5 years seen with the Bentall procedure, the need for reoperation after Bentall and VSARR are then comparable thereafter.
Kirsh, in 1976, reported a 70% success rate in surgery to repair a torn aorta, based on 10 years of experience as a surgeon. Therefore, for those who make it to the hospital (85% do not), are successfully diagnosed in time and are quickly operated upon, the chances of survival are higher. [5]
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."
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.

Inflammatory Aortic Aneurysms occur typically in a younger population compared to the typical Abdominal Aortic Aneurysm group. Risk of rupture for the IAA group, due to thinning of aneurysm walls, are also rare due to inflammation and fibrosis [4] Unruptured inflammatory AAAs are usually symptomatic: [citation needed] abdominal or back pain (70 ...
A transesophageal echocardiogram during the operation and prior to the repair will be important to define the exact deformation of the aortic valve and thus the mechanism of regurgitation. [citation needed] In order to best accommodate the complex geometry of the aortic valve, these procedures are generally performed through open-heart surgery.
