Abstract: ObjectiveTo explore the jailed balloon(JBT) technique for coronary bifurcation lesions. MethodsThe database PubMed, EMBASE, the Cochrane Library database, CNKI and WanFang database were used to collect the relevant research literature on the application  of JBT to the treatment of coronary bifurcation lesions. The  metaanalysis was applied to the comprehensive quantitative evaluation of the literature collected. The patients treated with JBT was set as a group, while those who hadn't belong to the control group.REVMAN 5.3 was used for statistical analysis. ResultsA total of 8 studies were included, which involved 360 cases as JBT group and 585 as the control group. Compared with the control group,  JBT group saw their time of percutaneous coronary intervention(WMD=-20.41, 95%CI=-24.00-16.82,P<0.05) significantly shortened,  and lower incidence of complications such as side support occlusion, dissection or slow blood flow (RR=0.40,95%CI=0.240.66，P<0.05), and there were no significant differences in main adverse coronary event (MACE)(RR=0.58,95%CI=0.311.07，P=0.08).ConclusionCompared with the traditional sidebranch (SB) protection technique, JBT can shorten the operation time, reduce the incidence of complications of SB occlusion, dissection or slow blood flow,  and the incidence of MACE events.
