Abdominal Aortic Aneurysm Open Repair

What Is an Abdominal Aortic Aneurysm Open Repair?

Abdominal aortic aneurysm (AAA) repair is a procedure used to treat an aneurysm (abnormal enlargement) of the abdominal aorta. Repair of an abdominal aortic aneurysm may be performed surgically through an open incision or in a minimally-invasive procedure called endovascular aneurysm repair (EVAR).

Open repair of an abdominal aortic aneurysm 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. Open repair remains the standard procedure for an abdominal aortic aneurysm repair.
