TL;DR: The effects of different techniques of preparing autologous vein grafts on acute thrombogenicity have been studied in a sheep model and it was found that storing grafts at room temperature or rinsing with different solutions seemed to be of minor importance.
Abstract: The effects of different techniques of preparing autologous vein grafts on acute thrombogenicity have been studied in a sheep model Storing grafts at room temperature or rinsing with different solutions seemed to be of minor importance, whereas distending them to a pressure of 400 mm Hg significantly reduced patency and increased platelet accumulation and thrombus formation

TL;DR: Although more compliant, in this study polyurethane urea grafts behaved much like PTFE ones, but the activity was always somewhat higher in the polyurehane grafts.
Abstract: The acute thrombogenicity of a new polyurethane urea graft has been compared with polytetrafluoroethylene (PTFE) grafts using labelled homologous platelets in the carotid arteries of sheep in a low-flow model. There was no difference in patency. Thrombus weight and thrombus free surface were the same in both types of graft after 4 h. The accumulation of homologous 32P platelets was measured at the 2 anastomoses and at a midgraft position. At no point was there any statistically significant difference between the 2 grafts, but the activity was always somewhat higher in the polyurethane grafts. Although more compliant, in this study polyurethane urea grafts behaved much like PTFE ones.
