Objective To analyze the efficacy of no-touch technique and traditional technique in drawing great saphenous vein during coronary artery bypass grafting. Methods We searched the literatures on no-touch technique versus traditional technique in drawing great saphenous vein during coronary artery bypass grafting in PubMed, Cochrane Library, Chinese Journal Full-text Database, Wanfang database between January 1997 and November 2017. Jadad scale was used for quality verification. RevMan 5.0 was used for analysis. Results Six studies were included. Jadad scale for both 6 randomized controlled trials was 5 points. Meta-analysis showed that there was no statistical difference in postoperative mortality between the two groups with RR=0.68 and 95%CI 0.11 to 4.11(P=0.67). There was no statistical difference in leg wounds with RR=1.46 and 95%CI 0.23 to 9.16 (P=0.68). There was no statistical difference in short-term cardiogenic death with RR=0.33, 95%CI 0.10 to 1.03 ( P=0.06). The no-touch group’s long-term cardiogenic death was significantly lower than the traditional group withRR=0.36, 95%CI 0.16 to 0.79(P=0.01). Postoperative no-touch group’s short-term patency rate was significantly better than that of the traditional group with MD=3.08 and 95%CI 1.58 to 5.99 (P<0.01). The long-term patency rate in the no-touch group was also higher than that of the traditional group withMD=3.08 and 95%CI 1.58 to 5.99 (P<0.01). Conclusion Compared with the traditional group, the no-touch group increases postoperative long-term survival rate, short-term and long-term patency rate.
Objective To compare the patency of the postoperative vessel bridge grafts between the no-touch technique and the conventional technique for saphenous vein harvest in the coronary artery bypass grafting. Methods A total of 70 patients underwent coronary artery bypass grafting from January 2014 to January 2015 in the First Affiliated Hospital of Zhengzhou University. They were randomly divided into a conventional technique group (saphenous vein obtained by traditional technique) and a no-touch technique group (saphenous vein obtained by no-touch technique). There were 34 patients in the conventional technique group, including 16 males and 18 females with an average age of 61.6±6.4 years. There were 36 patients in the no-touch technique group, including 16 males and 20 females with an average age of 62.2±6.6 years. The 1-year postoperative coronary CT angiography (CTA) results were compared. Results Seventy patients underwent coronary CTA examination 1 year postoperatively. The patency rate of the conventional technique group and no-touch technique group were 83/116 (71.6%) and 113/122 (92.6%). Logistic regression analysis showed a statistical difference between the non-touch technique and the conventional technique (P<0.05). Conclusion The short-term patency rate of vessel bridge grafts is higher when the no-touch technique is used.
