Key result
The no-touch saphenous vein harvesting technique preserves perivascular adipose tissue and demonstrates improved long-term graft patency rates compared to conventional harvesting in coronary artery bypass grafting.
Why the study?
Saphenous vein grafts remain commonly used worldwide despite high failure rates, motivating the need to review the no-touch harvesting technique which has demonstrated improved long-term graft patency.
Does the no-touch saphenous vein graft harvesting technique improve long-term graft patency in patients undergoing coronary artery bypass grafting?
Does the no-touch saphenous vein graft harvesting technique improve long-term graft patency in patients undergoing coronary artery bypass grafting?
The no-touch harvesting technique for saphenous vein grafts offers a promising strategy to improve long-term graft patency in patients undergoing coronary artery bypass grafting.
May support no-touch harvesting in CABG; leaves open need for RCTs before practice change.
Although the multi-arterial grafting strategy is widely accepted in Japan, saphenous vein grafts (SVGs) are still commonly used worldwide. SVGs have a high failure rate of 8–25% at 1 year, with only 50–60% remaining patent after a decade. Pathological changes, such as intimal hyperplasia and atherosclerosis have been well studied, and graft distention, size mismatch and deprivation of perivascular adipose tissue are risk factors related to long-term SVG graft patency. The new no-touch harvesting technique has demonstrated improved long-term graft patency rates. This review summarizes the relevant literature detailing no-touch SVG harvesting in coronary artery bypass grafting.

Tatsuhiko Komiya (2022) conducted a review in Coronary artery disease requiring coronary artery bypass grafting. No-touch saphenous vein graft harvesting vs. Conventional saphenous vein graft harvesting was evaluated. The no-touch saphenous vein harvesting technique preserves perivascular adipose tissue and demonstrates improved long-term graft patency rates compared to conventional harvesting in coronary artery bypass grafting.
