目的:探讨直接冠状动脉内支架术治疗冠心病(CHD)疗效.方法:对21例CHD置入冠脉内支架的连续观察病例进行分析.结果:21例CHD患者中,梗塞相关血管为左前降支13例,左回旋支3例,右冠状动脉5例.共置入3种支架合计21个.术后残余狭窄程度由术前76.3±4.9％降至术后1.32±5.4％.手术成功率95.4％.结论:在所选择的患者中,直接冠状动脉内支架治疗是有效的,早期效果好而且可降低再梗塞发生率,并明显减少再次的靶血管上运重建.“,”Objective: To evaluate the efficiency of primary intracoronary stebting in coronary heart disease (CHD) patients. Methods: Twenty-one patients, undergone successful intracoronary stenting and were analyzed. Results: Among these patients, there were 18 males and females, age 43 to 65 years with an average of 54.22. Infact-related arteries (IRA) were LAD in 13 patients, LCX in 3 and RCA in 5. Twenty-one stems of 3 kinds were implanted. Residual stenosis decreased from (76.3 ± 4.9)% to (1.32 ± 5.4%). success the of the procedure was 95.4%. Conclusion: Primary intracoronary stenting is an effcient therepeutic procedure which can reduce the occurrence of CHD and revascularization of the IRA.
