The largest artery in the body, the aorta carries blood from the heart to the rest of the body. Normally, the aorta’s walls are thick and muscular, allowing them to withstand a large amount of pressure. However, if an area of the artery weakens, pressure builds within the artery, creating a balloon-like bulge called an aortic aneurysm—usually in the chest or low abdomen.

To repair an aortic aneurysm, patients undergo a minimally invasive procedure, generally performed under local, rather than general, anesthesia. The technique allows patients to go home within 24 hours and return to normal activities sooner.
