Abstract:
Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.
