Expanded polytetrafluoroethylene as a microvascular graft: an experimental study. 1980

D H Lidman, and B Faibisoff, and R K Daniel

The patency rates of expanded polytetrafluoroethylene (PTFE) vascular grafts with internal diameters of 1.0-3.0 mm were evaluated in three different species (dogs, rabbits, and rats). An overall 2-week patency rate of 14 (23%) of 60 was obtained, with the exception of 10 (83%) of 12 grafts 1.8 mm in diameter inserted in the carotid arteries of rabbits. The presence of numerous variables in the structural properties of PTFE may explain the variable results reported in the literature and this study. Heparinization did not improve the results, nor did modification in suture technique. At the present time, PTFE cannot be considered an equivalent to or a substitute for autogenous vein grafts in microvascular surgery.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
