冠状动脉病变中分叉病变较为常见,约占经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)的15%～20%[1]。由于存在斑块移位、病变弹性回缩及支架内再狭窄,冠状动脉分叉病变的介入治疗存在许多难题[2]。经典挤压(Crush)支架技术支架可完全覆盖分支开口,但是与其他技术相比,Crush支架术支架内血栓发生率似乎有增加的趋势[3]。我们近年来采用改良mini-Crush支架技术(原mini-Crush技术采用两次对吻球囊扩张,而我们的技术只采用一次最终球囊对吻扩张,简化了步骤)治疗真性冠状动脉分叉病变,取得了良好的近期结果。 Bifurcation lesions are more common in coronary artery disease, accounting for 15% to 20% of percutaneous coronary intervention (PCI) [1]. Due to the presence of plaque displacement, elastic lesion and in-stent restenosis, there are many challenges in the interventional treatment of coronary bifurcation lesions [2]. The classic Crush Stent stent completely covers the branch opening, but there appears to be an increase in thrombus incidence in the Crush Stent stent compared to other techniques [3]. In recent years, we have adopted a modified mini-Crush stent technology (the original mini-Crush technology used to kiss the balloon dilatation, and our technology only uses a final balloon kiss expansion, simplifying the steps) for the treatment of true coronary bifurcation , Has made good recent results.
