An aneurysm is an enlarged and weakened section of an artery, and is a serious health concern because of the possibility of rupture and blood clots. While they do occur in other arteries, most aneurysms form in the aorta, the largest artery in the human body, running from the heart through the chest and abdomen. The most common type of aneurysms are abdominal aortic aneurysms or AAA.

To surgically repair or remove an aneurysm, the vascular surgeon makes an incision in the skin while the patient is under anesthesia. Through this incision he may perform "open" aneurysm repair or an endovascular procedure called "stent graft" aneurysm repair. The method chosen depends upon location and shape of the aneurysm as well as the health of the patient.
