Vascular prostheses currently in use for reconstruction of small diameter vessels tend to fail secondary to thrombogenesis. Dacron velour works well for large diameter arterial reconstruction. By coating it with an appropriate urethane its thrombogenic qualities may be nullified. Several Dacron materials were coated with various urethane preparations. As controls, alumina, various Dacron materials (woven, knitted, straight knitted and double velour), PTFE (polytetrafluoroethylene) and Dow Corning Medical Grade Silastic diluted with Xylene 3% and 50% by weight were tested. Dacron-urethane showed better thromboresistance than other materials conventionally used in vascular surgery. The urethanes tested are too stiff, but by coating the vascular prosthesis with a highly flexible urethane small diameter vascular prosthesis made of Dacron should have increased thromboresistance.
