冠状动脉造影及支架植入术在冠状动脉狭窄中的应用

目的：探讨冠状动脉造影术对冠状动脉狭窄的诊断价值和FTCA、支架植入术对冠状动脉狭窄病人的治疗效果。方法：回顾性分析冠状动脉造影143例，其中的54例76支病变冠状动脉植入支架59枚，包括前降支25枚、回旋支12枚和右冠状动脉22枚。结果：冠状动脉狭窄发生率依次为前降支、右冠、回旋支及其他分支。老年人冠状动脉狭窄的严重程度及多支病变狭窄的发生率较中青年明显增加。狭窄血管经PTCA及支架植入后血供明显改善，但仍有可能发生再狭窄。结论：冠状动脉造影术是诊断冠状动脉狭窄的金标准，经皮冠状动脉内支架植入术是治疗冠心病的有效方法。

Application of coronary angiography and stent implantation in coronary artery stenosis

Purpose To investigate the diagnostic value of coronary angiography for coronary artery stenosis, and to evaluate the treating effect of PTCA and stent implantation for it. Methods The data of 143 cases by coronary angiography were retrospectively analysed. 76 branches of coronary artery stenosis in 54 cases had been treated with intracoronary stents ( n = 59) including left anterior descending ( n = 25), left circumflex (n = 12) and right coronary artery (n = 22) , respectively. Results The stenosis of coronary artery occurred in left anterior descending most frequently, right coronary artery secondly, left circumflex thirdly and other branches. This disease was more serious in elder patients than youth one's. It was also much more likely to affect multiple branches. The blood supply could be improved significantly by PTCA and stent implantation, but restenosis might occur. Conclusion Coronary angiography is the gold standard for the diagnose of coronary artery stenosis. Percutaneously intracoronary stent is an effective treating method .
