Abstract:
Objective To evaluate the efficacy and safety of open occluded coronary artery branch through outside stent balloon expansion technique.Methods A retrospective analysis of 26 patients,26 interventional treat-ment of coronary bifurcation lesions were taken.All patients initially used conventional interventional techniques, branch reserve protection guidewire and main branch stent.When branch occlusion occured during operation and failed again through guidewire,small outer diameter of the balloon branch guidewire which was squeezed could be used to branch opening.The blocked branch opening was expanded outside of the stent,and the balloon was expanded after the guide wire enter into branch again.The main branch/branches kissing balloon inflation or main branch /branch double stenting would be used when necessary.Results Among 26 cases of bifurcation branch occlusion,25 cases successfully completed the outer stent balloon,achieved a branch balloon expansion after reentry guidewire,saved blocked branches and the rate of success was 96.2%,and 6 cases of the main branch and the branch kissing balloon dilatation,2 cases of remedial double stenting.Following -up for 1 -12(5.3 ±6.8)months after operation in 25 cases of patients,there was no death and myocardial infarction and other adverse cardiovascular events.Conclusion Out-side stent balloon expansion technique can improve the success rate of coronary occlusion branch opening,and it have fewer complications and worth of clinical application becasuse of its satisfactory results.
