What is the best known brand name of the material other than dacron often used to replace the aneurysmal portion of the aorta in OAS?
Open aortic surgery Open aortic surgery ("OAS", also known as Open aortic repair, "OAR") describes a technique whereby an abdominal or retroperitoneal surgical incision is used to visualize and control the aorta for purposes of treatment. OAS is used to treat aneurysms of the abdominal and thoracic aorta, aortic dissection, acute aortic syndrome, and aortic ruptures. Aortobifemoral bypass is also used to treat atherosclerotic disease of the abdominal aorta below the level of the renal arteries. In 2003, OAS was surpassed by endovascular aneurysm repair (EVAR) as the most common technique for repairing abdominal aortic aneurysms in the United States. In OAS for abdominal aortic aneurysm, the aneurysmal portion of the aorta is replaced with a graft, usually made of dacron or PTFE.
