Over time, the aneurysm shrinks. In some patients, when stents are not possible, open surgery (requiring an incision in your chest) may be necessary to repair the aneurysm by placing an artificial blood vessel into the aorta to replace the aneurysm.

Can an aneurysm shrink on its own?

Once an aneurysm develops along the aorta, it will not disappear or reduce in size on its own. Some small aneurysms will remain stable in size for many years, while others increase in size over time.

Can a aortic aneurysm go away?

Abdominal aortic aneurysms do not go away, so if you have a large one, you may need surgery. Surgery involves replacing the aneurysm with a man-made graft. Elective surgery, which is done before an aneurysm ruptures, has a success rate of more than 90 percent.
