Microvascular endothelial cell sodding of 1-mm expanded polytetrafluoroethylene vascular grafts.
The formation of an endothelial cell lining on the inner surface of polymeric grafts may reduce the inherent thrombogenicity of synthetic implants. Endothelial cell transplantation onto the luminal surface of grafts has been suggested as one method of creating new endothelial cell linings on grafts. The purpose of this study was to morphologically evaluate the very early events of healing (betw...
متن کاملEndothelial cell seeding of polymeric vascular grafts.
Pioneers in the field of small diameter graft development sought to promote graft endothelialization and, thereby, increase patency by transplanting a varying degree of autologous endothelial cells onto vascular grafts prior to implantation. This process has become known as endothelial cell seeding. The underlying hypothesis is quite simple; that is, by promoting the establishment of the patien...
متن کاملRelationship between flow and incidence of thrombosis in polytetrafluoroethylene vascular grafts in free microvascular flaps in lambs.
We have done an experimental study in lambs in which we investigated the influence of flow rate on free microvascular flaps using polytetrafluoroethylene (PTFE) vascular grafts. We set up five surgical groups in which blood flow was progressively increased through the PTFE vascular graft. In group I (venous autograft) we observed just one vascular thrombosis which was located at the site of the...
متن کاملPaclitaxel-coated expanded polytetrafluoroethylene haemodialysis grafts inhibit neointimal hyperplasia in porcine model of graft stenosis.
BACKGROUND The main pathology of haemodialysis graft stenosis is venous neointimal hyperplasia at graft-venous anastomoses. Neointimal hyperplasia is also observed in cases of coronary artery in-stent restenosis. Paclitaxel is a chemotherapeutic agent used to treat cancer, and has been proven to inhibit neointimal hyperplasia of coronary artery in-stent restenosis. In this study, we examined wh...
متن کاملSurgical outcomes after superior vena cava reconstruction with expanded polytetrafluoroethylene grafts.
OBJECTIVES Graft occlusion is a problem after superior vena cava (SVC) reconstruction for thoracic malignancy. Expanded polytetrafluoroethylene (ePTFE) is considered to be an optimal material for venous reconstruction. METHODS We reviewed the hospital records of 13 patients who underwent complete resection of thoracic malignancy invading the SVC, including SVC reconstruction with ePTFE grafts...
