The purpose of this study was to perform a prospective multicenter evaluation of the patency,
complications, and predictive factors of patency for 6-mm expanded polytetrafluoroethylene …

In a retrospective study of 66 PTFE arteriovenous fistulae and 71 BCH arteriovenous fistulae
for dialysis access, PTFE had a higher patency rate than BCH at 12 months (62.4 versus …

Polytetrafluoroethylene grafts have been the mainstay for hemoaccess at our dialysis unit
since 1976. Of 528 grafts placed in the forearm, 81 were evaluated for long-term patency …

A hundred patients with RCAV fistulas we compared with 100 patients with expanded PTFE
fistulas created during the same time period. The fistulas were analyzed to compare early …

During a 10-year period vascular access in 86 patients receiving long-term haemodialysis
was provided by the insertion of 100 polytetrafluoroethylene grafts. In 24 patients (28%) the …

In order to determine if serial, noninvasive evaluation of polytetrafluoroethylene (PTFE)
vascular access grafts could identify a subgroup of patients at risk for thrombosis, the …

Patency of 40 polytetrafluoroethylene (PTFE) and 40 autogenous vein arteriovenous grafts
for vascular access among 56 patients is compared. Most patients required access for …

During the study period a cohort of 170 of patients receiving long-term hemodialysis
treatment required placement of 214 polytetrafluoroethylene grafts for vascular access; …

During a seven year period, 189 expanded polytetrafluoroethylene (PTFE) grafts for
