冠状动脉内血管成形术中血管内支架植入六例报告

Intracoronary stent implataion during percutaneous transluminal coronary angioplasty:report of six cases

经皮冠状动脉内血管成形术（PTCA）的并发症急性血管闭塞和再狭窄出现影响其疗效。本文报告6例患者行PTCA术中出现急性血管闭塞和频临闭塞，植入血管内支架7只，失败1例。术中造影观察5例血管再通达TIMIⅢ级，1例达Ⅱ级。住院观察和随诊，1例死于泵衰竭，5例无心绞痛发作。均无出血、血栓形成等。结论：冠状动脉内血管内支架植入术是急性血管闭塞的及时有效的处理方法，并预防血管再狭窄的发生。

The clinical outcomes of percutaneoustransluminal coronary angioplasty (PTCA) are affected by their complications including acute vessel closure and restenosis. The article reports that six patients had received seven tracoronary stent implatations for the occurrences of acute and threatenedvessel closure during PTCA. lmplating stent was failure in one patient, the others were successful. In theprocedure of coronary angiography, the vessel reperfusion in five Patients achieved TIMI grade Ⅲ, in onepatient grade Ⅱ .In hospital and short-term followup, one case died of heart failure, there were no angiapectoris, no bleeding and no thrombosis complication. Conclusion: Intracoronary stent implantation is aprompt and effective method to treat acute andthreatened vessel clOSure, and prevent occurrence ofrestenosis.
