Key result
Infrainguinal bypass using TFE-coated PET grafts demonstrated no early occlusions in femoropopliteal positions, whereas 71% of femorotibial bypasses occluded within five days.
Why the study?
Does the woven polyethylene terephthalate (PET) vascular graft coated with tetrafluoroethylene (TFE) provide acceptable patency in patients undergoing infrainguinal bypass?
Observational (n=28)
Does the woven polyethylene terephthalate (PET) vascular graft coated with tetrafluoroethylene (TFE) provide acceptable patency in patients undergoing infrainguinal bypass?
The TFE-coated PET vascular graft demonstrates acceptable antithrombogenicity for femoropopliteal bypasses but is associated with unacceptably high early occlusion rates in femorotibial positions.
No takes yet. Share an insight, caveat, or question.
Supports selective femoropopliteal use; leaves open femorotibial efficacy pending prospective trials.
Onohara et al. (1998) conducted an observational in Peripheral arterial disease requiring infrainguinal bypass (n=28). Woven polyethylene terephthalate (PET) vascular graft coated with tetrafluoroethylene (TFE) was evaluated on Early graft occlusion and cumulative patency. Infrainguinal bypass using TFE-coated PET grafts demonstrated no early occlusions in femoropopliteal positions, whereas 71% of femorotibial bypasses occluded within five days.
