冠状动脉内支架植入术(附20例报告)

Coronary Artery Stent Implantation: A Report of 20 Cases

目的：探讨冠状动脉内支架植入术（ＣＡＳＩ）在冠心病介入治疗中的价值。材料与方法：对２０例２１支病变血管植入２１个不同类型的支架进行分析。结果：植入成功率９５．２％（２０／２１），病变狭窄度从８０％～１００％降到２０％～－１０％。在管腔扩张效果上，高压球囊优于低压球囊。未发生支架血栓及出血并发症。结论：ＣＡＳＩ可作为冠状动脉腔内成形术（ＰＴＣＡ）中急性闭塞和术后再狭窄的有效补救措施，而耐高压球囊的应用可能会降低并发症，获得较完美的影像效果。

Objective: To evaluate the coronary artery stent implantation in the treatment of the coronary artery disease. Materials and Methods: Coronary artery stent implantation was performed in 21 coronary arteries of 20 patients. Results: The success rate of operations was 95.2% (20/21). High pressure ballon was superior to low pressure ballon in producing dilatation effects. No complications occurred. Conclusion: Coronary artery stent implantation is an effective alternative in emergency treatment of acute occlusion and restructure of coronary artery occurred during or after percutaneous transluminal coronary angioplasty. The complications may be lowered by the use of high pressure ballon.
