Bifurcation lesions are frequently encountered, associated with greater procedural complexity and consequently are at higher risk for restenosis and stent thrombosis. Early trials in bifurcation percutaneous coronary intervention favored a provisional stenting approach, but contemporary randomized trials have highlighted potentially superior outcomes using a double-kiss crush technique in unprotected distal left main stem bifurcation lesions. Although the evidence is greatest for double-kiss crush, many operators favor a mini-crush or nano-crush single-kiss approach. In this review, the authors describe the iterations of the crush technique and the evidence for each and review general principles for bifurcation percutaneous coronary intervention.

经常遇到分叉病变，与更大的程序复杂性相关，因此再狭窄和支架血栓形成的风险更高。分叉经皮冠状动脉介入治疗的早期试验有利于临时支架置入方法，但当代随机试验强调了在无保护的左主干远端分叉病变中使用双亲挤压技术可能获得更好的结果。虽然双吻迷恋的证据最多，但许多运营商更喜欢迷你迷恋或纳米迷恋单吻方法。在这篇综述中，作者描述了挤压技术的迭代和每种技术的证据，并回顾了分叉经皮冠状动脉介入治疗的一般原则。
