No-touch saphenous vein graft harvesting technique for coronary artery bypass grafting

Research output: Contribution to journalArticle

Abstract

Objectives: Although the patency of internal artery grafts in coronary artery bypass grafting (CABG) is superior to that of saphenous vein grafts (SVGs), good long-term patency rates have been reported with SVGs harvested using the no-touch technique. Here, we report the early results of CABG with no-touch SVGs (NT-SVGs) along with the precautions required while handling these grafts. Methods: This retrospective study included 41 patients who underwent CABG with NT-SVGs between May 2016 and March 2018. NT-SVGs were harvested with minimal electric scalpel use, and post-harvesting vascular overdilation with a syringe was not performed. Blood with heparinized saline was used to prevent vascular endothelial damage. A drain was inserted into the SVG harvest site, which was closed with a single interrupted suture, and elasticated bandage and compression stockings were used to prevent fluid retention and avoid delayed wound healing. Results: There was no case of postoperative thoracotomy due to bleeding or myocardial infarction, and postoperative graft assessment confirmed graft patency in all patients, with a little mismatch between the diameters of SVG and the anastomotic vessel. Delayed wound healing at the graft harvest site seemed to improve after introducing the above procedures. Conclusions: Early results of CABG with NT-SVGs were good. Some precautions must be taken during harvesting and anastomosis. Taking precautions described in this study may help reduce the risk of perioperative complications and make the no-touch technique the standard procedure for harvesting SVGs for CABG.
