RESUMO
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.
RESUMO
Objective:To investigate the clinical efficacy of trimetazidine combined with salvia ligustrazine injections in the treat-ment of unstable angina in coronary heart disease with type 2 diabetes. Methods:Totally 76 patients of unstable angina with type 2 di-abetes were randomly divided into the control group and the observation group with 38 cases in each. The control group received trime-tazidine on the basis of the conventional treatment, 20mg,po,tid, while the patients in the observation group received salvia ligustrazine injections additionally, 10ml, ivd,qd. The treatment course was 2 weeks, and the clinical efficacy, blood fat, blood rheology and the other indices were observed after the treatment. Results:After the treatment, the effective rate of the control group and the observation group was 65. 79% and 86. 84%,respectively with statistically significant difference(P<0. 05), the improvement of blood fat and blood rheology in the observation group was better than that in the control group (P<0. 05), the angina frequency and duration, and nitroglycerin consumption in the observation group was significantly lower than those in the control group(P<0. 05). Conclusion:The combination application containing trimetazidine and salvia ligustrazine shows exact clinical efficacy with promising safety and compli-ance, which is valuable in the clinical application.
