Although the long saphenous vein remains the most commonly used conduit in coronary revascularization, traditional open vein harvest may lead to significantly impaired wound healing and post-operative pain. To this end, endoscopic saphenous vein harvesting techniques have been shown to reduce post-operative morbidity. Studies have shown that endothelial integrity and luminal nitric oxide synthase (NOS) are better preserved with novel "no-touch" techniques; however, the effect and the associated mechanism of endoscopic vein harvest on endothelial integrity and function remain unknown. Therefore, in the present proposal, we will collect the saphenous vein segements immediately after harvesting, reperfusion, and grafting, and then use enzyme-linked immunosorbant assay (ELISA), immunohistochemical staining (IHC), and real-time polymerase chain reaction (RT-PCR) to detect the expression and distribution of endothelial NOS (eNOS), endothelin-1 (ET-1), vascular cell adhesion molecule-1 (VCAM-1), intracellular adhesion molecule-1 (ICAM-1), and platelet endothelial cell adhesion molecule-1(PECAM-1) at protein and RNA levels in the endothelium of saphenous veins. The major aim of this study is to elucidate the effect and mechanism of endoscopic saphenous vein harvesting on endothelial properties as compare to conventional open vein harvest technique.
