应用Partner支架完成Crush技术治疗冠脉分叉病变的即刻及近期随访结果

目的评价国产西罗莫司药物洗脱支架（Partner）完成Crush技术治疗冠状动脉分叉病变的安全性及有效性。方法冠状动脉造影证实为冠状动脉真性分叉病变（Medina分型为1．1．1），主支和分支均选择Partner支架完成Crush技术，术后6月进行冠状动脉造影随访。结果共30例患者入选，冠脉分叉病变31处。患者平均年龄（61．7±11．2）岁，其中男性占66．7％。31处分叉病变分布：前降支与对角支51．6％，左主干与前降支和回旋支32．3％，右冠脉左室后侧支与后降支9．7％，回旋支与钝缘支6．5％。非顺应性球囊高压扩张占58．1％，最后完成球囊对吻技术96．8％。主支和分支置人支架（1．50±0．55）枚和（1．10±0．34）枚，支架长度为（37．2±1．2）mm和（21．6±0．83）mm，支架直径为（3．27±0．51）mm和（2．76±0．48）mm。近期随访主要心血管事件（MACE）的发生率为3.3％。结论西罗莫司洗脱支架Partner完成Crush技术治疗冠脉分叉病变是安全、有效的，而且相对低的医疗费用使国产西罗莫司洗脱支架Partner在复杂病变中的应用更具有吸引力。

Partner stents for crush technique in coronary bifurcation:immediately and short-time follow-up results

Objective To estimate the security and validity of crush technique in the therapy of coronary bifurcation lesions by our national sirolimus-eluting stent （Partner）. Methods After coronary angiography, crush technique was used to accomplish the main branch and side branch lesions in truly bifurcation lesions （Medina type l.l.1 ）. Six months later, coronary angiography was reexamined. Results There were 30 patients enrolled and total of 31 bifurcation lesions. The mean age was 61.7±11.2 years, male was 66.7%. The 31 bifurcation lesions included： LAD-D （51.6%）, LM-LAD and LCX （32.3%）, RCA-PL and PD （9.7%） and LCX-OM （6.5%）. The non-compliance balloon was used to expand lesions by high pressure（58.1% ）, finally the kissing balloon technique was completed （96.8%）.The stent number in main branch and side branch vessels was 1.5±0.55 vs 1.1 ±0.34, the length was （37.2±1.2）mm vs （21.6±0.83）mm, the diameter was （3.27±0.51）mm vs （2.76±0.48）mm. The rate of main cardiac event（MACE） after PCI was 3.3%. Conclusion It is security and validity to treat the bifurcation lesions by crush technique with Partner sirolimus-eluting stent, and this stent is more attractive in the therapy of complicated coronary lesions in our country because of the lower fee-for-service.
