Abdominal Aortic Reconstruction Using PTFE(Polytetrafluoroethylene)

ABSTRACT

Fifty cases of abdominal aortic reconstruction using PTFE were performed between january 1991 and february 1998 at the Department of Surgery, Chonnam University Hospital. The thirty-five of 50 cases were abdominal aortic aneurysm and the other 15 cases were aortoiliac occlusive disease. Patients were analysed on the basis of sex, age, associated disease, size of aneurysm, operative method, mortality, and cause of death. There were 43 men and 7 women and the mean age was 64.9 years. Hypertension in 24 cases is the most common associated disease, following by ischemic heart disease in 5 cases, COPD in 5 cases. Aorto-bifemoral bypass graft using PTFE was done in 17 cases and aorto-biiliac bypass in 33 cases. The most common complication following surgery was graft occlusion in 6 cases, and other complications were prosthetic infection, postoperative bleeding and ischemic colitis. The cases of death were hypovolemic shock (2), acute renal failure (1), and sepsis (1). There was no evidence of PTFE oriented prosthetic graft complications.
