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]
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."
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 ...
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.
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 most common cause is an abdominal aortic aneurysm that has ruptured spontaneously. Aortic rupture is distinct from aortic dissection, which is a tear through the inner wall of the aorta that can block the flow of blood through the aorta to the heart or abdominal organs.

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.
