Abstract
Surgical results using ultrafine polyester fiber graft (TORAY GRAFT)in patients with abdominal aortic aneurysm were examined. From January 1992 to May 1996, vascular replacement using this graft were performed in 54 cases. The surgical mortality was 19% and 3% in cases undergoing emergency surgery and elective surgery, respectively.No death was related to the graft.During an average follow-up period of 2.8 years, the cumulative survival rate was 93% at 1 year and 85% at 2 years.Results of computed tomography and digital subtraction angiography during the late phase showed that the internal diameter of the graft extended by 10% compared with the standerd size and regenerative intima-like hypertrophy was observed on CT images in 27.7% of the cases.
