Intraarterial biocompatibility of polyethylene terephthalate self-expandable stents implanted in porcine peripheral arteries.

Rationale And Objectives: We tested deployment feasibility and intraarterial biocompatibility of polyethylene terephthalate (PET) self-expandable vascular stents in a porcine peripheral artery model.

Methods: To assess the thrombogenicity and neointimal response to oversized PET self-expandable stents, we implanted 10 stents in porcine common iliac arteries, followed by a 6-mm balloon inflation to 6 atm.

Results: All pigs survived until the study termination 6 weeks after stent implantation.
