Backgrounds:To compare the early outcomes of endoscopic, no-touch, and conventional open vein-graft harvesting for patients undergoing CABG surgery in one single heart center. Methods:An observational study of 243 patients undergoing isolated CABG surgery with endoscopic, no-touch and conventional open-vein graft harvesting methods between 2015 and 2017 performed by one single operation team.Graft patency rate, all-cause mortality, Secondary outcome included wound complications and the composite of death, recurrent angina, myocardial infarction, and revascularization were evaluated at the 12thmonth.ResultsBased on our database, 67% of patients received conventional open vein-graft harvesting, 16% received endoscopic harvesting and 17% received no-touch vein-graft harvesting during CABG surgery. After propensity score adjustment for clinical characteristics, there were no significant differences between one-year mortality rates and the composite of death, recurrent angina, myocardial infarction. Endoscopic vein-graft harvesting was associated with lower harvest site wound complications relative to no-touch group and conventional open vein-graft harvesting group. No-touch group reveals the best patency rate than the other 2 groups at the 12thmonth post operation. Conclusion:Among patients undergoing CABG surgery, the use of endoscopic vein- graft harvesting compared with conventional open vein-graft harvesting was not associated with increased mortality and complication morbidity, whereas no-touch group may have the best long-term results with a remarkable early patency rate.
