The Short-Term Patency Rate of a Saphenous Vein Bridge Using the No-Touch Technique in off-Pump Coronary Artery Bypass Grafting in Vein Harvesting

Abstract

Objective This study aimed to examine the short-term effect of the no-touch technique on the patency rate of a great saphenous vein (GSV) bridge used during off-pump coronary artery bypass grafting (OPCABG). Methods Between June 2018 and September 2020, 140 patients undergoing OPCABG, with grafts obtained from the GSV using the “no-touch” technique or the left internal mammary artery (LIMA), were enrolled in this study. The early clinical results and short-term patency rate of the OPCABG were evaluated at a three-month follow-up by comparing the patency rate of the LIMA bridge and the GSV bridge obtained by the no-touch technique. This study also analyzed the impacts of the postoperative complications of the lower limbs and the distribution area of diseased vessels on the patency rate of a GSV bridge obtained by the no-touch technique at an early stage. Results No perioperative death or adverse cardiovascular or cerebrovascular events occurred in the 140 patients undergoing OPCABG. The difference in the early patency rate between the GSV bridge obtained by the no-touch technique and the LIMA bridge was not statistically significant (95.9% vs 97.1%, p = 0.501). There was no significant difference in the patency rate between an end-to-side anastomosed venous bridge and a LIMA bridge (95.0% [248/261] vs 97.1% [136/140], p = 0.314). The overall patency rate of a no-touch vein bridge in the right coronary artery region was lower than it was in the left coronary artery region (93.8% [165/176] vs 97.9% [183/187], p = 0.049). Conclusion The no-touch technique may improve the early patency rate of a GSV bridge, and its effect is similar to that of a LIMA bridge.

Therapeutic Efficacy of a Staged Hybrid Technique vs. Coronary Artery Bypass Surgery Grafting in The Treatment of Multi-Vessel Coronary Artery Disease

“…Thus, in clinical practice, SVG is preferred for revascularization. As compared with the artery, the long-term patency rate of SVG is compromised [Kim 2008;Zhao 2021]. Although there is no comparative study between them, available findings indirectly reveal that the incidence of restenosis at 12 months after implantation of drug-eluting stents (DES) is lower than that after SVG [Wu 2010].…”
