Abstract

Aim: We evaluated a polyurethane vascular access graft (TVAG), a hybrid polytetrafluoroethylene graft (hPTFEG), and an expanded polytetrafluoroethylene graft (ePTFEG) for postoperative complications and graft patency in their use as prosthetic devices of vascular access for hemodialysis. Methods: Between August 1993 and October 2001, we treated 200 patients in whom A-V fistulas were placed by the same surgeon. These were divided into the following four groups according to the type of blood access: 27 cases of ePTFEG, 23 cases of TVAG, 22 cases of hPTFEG, and 128 cases of an autogenous A-V fistula. We calculated the cumulative patency rates by the Kaplan-Meier method, including primary (problem-free) and secondary (revised or functional) patency rates. Results: The hPTFEG group experienced few thromboses. The absence of perigraft edema in the TVAG group permitted the early use of the TVAG within a few postoperative days for hemodialysis. Among the three graft groups, the primary patency was the best in the hPTFEG group (94.7% at 1 year and 86.1% at 2 years), with a significant difference versus the ePTFEG group. In regard to secondary patency, hPTFEG had an excellent patency of 100% at 1 year and 90.9% at 2 years, and TVAG had a comparable patency with that of ePTFEG. Conclusion: The hPTFEG was considered superior to ePTFEG in terms of being complication-free and had the excellent 2 year secondary patency of 90.9%. TVAG, with a patency equal to that of ePTFEG, could be used immediately after implantation due to the absence of limb edema.
