The patency of graft and anastomoses in sequential and individual coronary artery bypass grafting: A meta-analysis

OBJECTIVE: To compare the patency of graft and anastomoses in sequential and individual coronary artery bypass grafting (CABG). METHODS: Our study used the Cochrane Library database, Excerpta Medica database, Web of Science, and PubMed. Studies comparing the outcomes of graft or anastomosis patency were assessed independently by two reviewers to identify the literature of satisfaction. We used Review Manager and STATA software for statistical analysis. RESULTS: Fifteen cohort studies were analyzed, including 10681 patients, 12957 grafts, and 4341 anastomoses, under sequential and individual CABG. Compared with the sequential group, the individual one is statistically significant in the graft patency [risk ratio (RR)=1.07, 95% confidence interval (CI ) 1.01–1.13; p=0.02] and anastomosis patency (RR=1.06, 95% CI 1.01–1.12; p=0.005). CONCLUSION: Our study suggested that the patency of the individual group, in terms of graft and anastomosis patency, is better than that of the sequential one.
