ABSTRACT
Objective To evaluate the feasibility of jailed-balloon technique(JBT) in the treatment of true coronary bifurcation lesions.Methods From March 2013 to October 2014,a total of 71 patients who received coronary angiography,were diagnosed as true coronary bifurcation lesions and then underwentpercutaneous coronary intervention(PCI) in the Department of Cardiology of the Second Affiliated Hospital of Kunming Medical University was divided into group A(jailed balloon side branch protection group,28 cases) and group B(traditional side branch protection group,43 cases).The perioperative complications,X-ray exposure time,the number of intervention supplies,the total expenses,the incidence of adverse cardiovascular events and other indicators between the groups were compared,and the feasibility of JBT was evaluated.Results There were no significant differences between the two groups in perioperative complications(P＞0.05),postoperative adverse cardiovascular events and restenosis rate of side branch after angiography(P＞ 0.05),but the PCI related indicators (including the balloon use number,PCI operation time,the amount of X-ray exposure,wire number,the amount of contrast agent and operation cost) in group A were significantly lower than those in group B(P＜0.05).Conclusion JBT applied in the treatment of true coronary bifurcation lesions can reduce the operative time,X-ray irradiation time and related medical expenses.
