The saphenous vein is the most commonly used conduit in patients undergoing coronary artery bypass surgery. Graft patency is improved using the no-touch technique where the vein is harvested with minimal trauma, avoiding high pressure distension and maintaining normal vessel architecture. Various cells that are damaged when using conventional harvesting are preserved using the no-touch technique and are a source of nitric oxide. The no-touch technique is becoming accepted more widely as is the role of nitric oxide in improved saphenous vein graft patency. However, there are conflicting views regarding the tissue sources of nitric oxide.
