Effects of different graft preparation techniques on the acute thrombogenicity of autologous vein grafts. An experimental study in sheep.

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.
