The 10-year survival rate after the repair of an aortic aneurysm is 59 percent, as the National Center for Biotechnology Information reports. This survival rate remains constant whether the aneurysm repair is elective or the aneurysm has ruptured.
Long-term survival rates after aortic aneurysm repair are also constant across populations who have open surgery and those who receive less-invasive procedures, according to Johns Hopkins Medicine. While the less-invasive procedure has some benefits for younger patients, those over 70 do not show any increased survival as a result. Repair of aneurysms in patients over 70 appears to add no significant life expectancy compared to simply leaving the aneurysm untouched.
