no-touch technique
A surgical approach that minimizes manipulation of saphenous vein grafts to preserve endothelial function.
Full Definition
A vein harvesting technique that maintains the saphenous vein in its natural tissue bed with surrounding pedicle intact, avoiding direct contact with the venous endothelium. This method preserves the vasa vasorum and reduces endothelial damage that can lead to early graft failure. The technique contrasts with conventional harvesting methods and has been associated with improved long-term graft patency and reduced need for repeat revascularization procedures.
Usage
Usage note: Hyphenate when used as compound modifier. Specific to vascular surgical contexts.
