Comparison of Conventional and No-Touch Techniques in Harvesting Saphenous Vein for Coronary Artery Bypass Grafting in View of Endothelial Damage

Abstract

Endothelial integrity and adenosine, iNOS, and VEGF immunoreactivities were better preserved when the no-touch technique was used for vein graft harvesting. The mechanical protection provided by the cushion of surrounding tissue in the no-touch group and the vasorelaxation and thromboresistant activities of nitric oxide may be responsible for the reduction in vasospasms and the improved patency rate.
