Abstract

Thrombosis and intimal hyperplasia are the principal causes of small‐diameter vascular graft failure. To improve the long‐term patency of polyurethane vascular grafts, we have incorporated both poly(ethylene glycol) and a diazeniumdiolate nitric oxide (NO) donor into the backbone of polyurethane to improve thromboresistance. Additionally, we have incorporated the laminin‐derived cell adhesive peptide sequence YIGSR to encourage endothelial cell adhesion and migration, while NO release encourages endothelial cell proliferation. NO production by polyurethane films under physiological conditions demonstrated biphasic release, in which an initial burst of 70% of the incorporated NO was released within 2 days, followed by sustained release over 2 months. Endothelial cell proliferation in the presence of the NO‐releasing material was increased as compared to control polyurethane, and platelet adhesion to polyethylene glycol‐containing polyurethane was decreased significantly with the addition of the NO donor. © 2007 Wiley Periodicals, Inc.

  • Endothelialization can alleviate thrombosis and intimal hyperplasia complications that cause small diameter vascular graft failure without systemic anticoagulants.

    “The West115 and Wang114 groups both reported that NO releasing/generating grafts encourage endothelialization/endothelial cell proliferation, which can alleviate the complications of thrombosis and intimal hyperplasia (IH) that cause the failure of small diameter vascular grafts without the use of systemic anticoagulants.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
