Publikováno v: Surgery. 112(5)

In baboons, nonreinforced (unwrapped) 60 microns internodal distance polytetrafluoroethylene grafts form a complete endothelial lining within 2 weeks by capillary ingrowth through the wall. Smooth muscle cells then grow under the endothelium and prol

In a previous study of arterial bypass grafts (4 mm polytetrafluoroethylene [PTFE]) in baboons we observed that endothelial and smooth muscle cells (SMCs) formed the neointima and were derived from the cut edges of adjacent artery. The purpose of thi

The effect of rigid external support on vein graft adaptation to the arterial circulation

Autor: T R, Kohler, T R, Kirkman, A W, Clowes

Publikováno v: Journal of vascular surgery. 9(2)

In previous experiments vein graft wall thickening stopped when the ratio of lumen radius to wall thickness equaled that of a normal artery. This led us to postulate that wall stress, which this ratio determines, regulates wall structure. To test thi
