无球囊对吻单支架植入术治疗分叉病变的近期疗效

目的：通过比较分叉病变经皮冠状动脉介入治疗术（PCI）3种处理方法的近期疗效，探讨最简单处理方法-无球囊对吻单支架植入术的安全性及有效性。方法：入选主支血管即刻造影成功PCI患者81例，分成三组：无球囊对吻单支架组，主支血管植入药物洗脱支架（DES）后，边支血管不予任何处理；球囊对吻单支架组，主支植入DES后，边支血管予球囊对吻扩张；球囊对吻双支架组，主支和边支均植入DES后，予球囊对吻。6个月临床随访观察主要不良心血管事件（MACE）发生情况，以及定量冠状动脉造影（QCA）评价血管再狭窄率和血管狭窄程度。结果：术后6个月，虽然三组间边支血管开口狭窄程度[（65．3±19．6）％、（59．9±17．7）％和（46．8±11．5）％，P〈0．001]有显著性差异，但是三组间MACE发生率（12．1％、14．8％和19．0％，P〉0．05）和主支血管再狭窄率（6．1％、7．4％和9．5％，P〉0．05）差异无显著性。结论：主支血管即刻造影成功PCI患者3种处理方法的近期临床疗效并无显著性差异，提示无球囊对吻单支架植入术治疗分叉病变安全有效。

Short-term clinical outcomes of one stent technique without final balloon kissing in treatment of coronary bifurcation lesions

Objective： Compare the short-term clinical outcomes of the three different methods in the treatment of coronary bifurcation lesions with rapamycin-eluting stents and explore the simplest method, one stent technique without final balloon kissing, is feasible and safe？ Methods： A total of 81 patients with successful PCI enrolled in this study were categorized into 3 groups： stenting the main vessel without final balloon kissing （group A）, stenting the main vessel with final balloon kissing （group B）, stenting the main vessel and side-branch with final balloon kissing （group C）. Six month clinical follow up was conduced to record major adverse cardiac events （MACE）, and quantitative coronary angiography （QCA） was performed to measure binary coronary restenosis rate and coronary stenosis percentage. Results： Although 6-month follow up showed that among the three groups there were significant differences in coronarystenosis percentage [（65.3±19.6）%, （59.9±17.7）%, （46.8±11.5）%, P〈0.001], inostia of sidebranch, there were no significant differences in MACE （12. 1%, 14.8% and 19.0%, P〉0.05） and binary coronary restenosis rate of the main vessel （6.1%,7.4% and 9.5%, P〉0.05）. Conclusion： There are no significant differences in the short-term clinical outcomes among the three groups, it indicating the simplest method with one stent technique without final balloon kissing may be feasible and safe.
