Bovine carotid artery heterografts versus polytetrafluoroethylene grafts . A prospective , randomized study . A prospective , randomized comparison of BCAH and PTFE vascular access grafts resulted in no statistically significant difference when analyzed for survival rates of complications , types of complications , reasons for failure , and clot salvageability . The results in diabetic patients were similar to those in nondiabetic patients . The majority of retrospective studies and subjective experiences favor PTFE grafts over BCAHs . The explanation may be part that BCAH preceded PTFE grafts into clinical use , and inexperience in the operating room and in the dialysis unit had an effect on BCAH results . A review of impressions of the graft materials indicated a decided preference for PTFE grafts .
