How is an abdominal aortic aneurysm open repair (AAA) performed?

Open repair of an abdominal aortic aneurysm (AAA) -- a bulging, weakened area in the wall of the aorta (the largest artery in the body) -- involves an incision of the abdomen to directly visualize the aortic aneurysm. The procedure is performed in an operating room under general anesthesia. The surgeon will make an incision in the abdomen either lengthwise from below the breastbone to just below the navel or across the abdomen and down the center. Once the abdomen is opened, the aneurysm will be repaired by the use of a long cylinder-like tube called a graft. Grafts are made of various materials, such as Dacron (textile polyester synthetic graft) or polytetrafluoroethylene (PTFE, a non-textile synthetic graft). The graft is sutured to the aorta, connecting one end of the aorta at the site of the aneurysm to the other end of the aorta.
