no-touch technique
Surgical approach that minimises manual manipulation of saphenous vein grafts to preserve endothelial function.
Full Definition
The no-touch technique is a harvesting method for saphenous vein grafts used in coronary artery bypass surgery that preserves the vein's surrounding tissue and vasa vasorum. Unlike conventional harvesting that strips the vein of its adventitial layer, this technique maintains the natural support structure, leading to improved long-term graft patency. The preserved adventitial tissue provides nutrients to the vessel wall and may reduce the inflammatory response that contributes to graft failure.
Usage
Usage note: Hyphenate when used as an adjective. Capitalise only when beginning a sentence.
