药物洗脱球囊在冠状动脉分叉病变介入治疗中的作用

即使在药物洗脱支架时代，分叉病变经皮冠状动脉介入治疗也常常复杂而难以获得理想的结果。药物洗脱支架植入后存在内皮愈合延迟、局部过敏性炎症反应、支架内血栓风险增加等问题。药物洗脱球囊带来新的希望，既能抑制新生内膜又不增加血栓风险，本文对药物洗脱球囊在分叉病变的应用情况做一综述。

Drug Eluting Balloon in the Interventional Treatment of Coronary Artery Bifurcation Lesions

Percutaneous coronary interventions for bifurcation lesions are often complex and associated with an unsatisfactory outcome, even in the era of drug eluting stents. The implantation of drug eluting stent induced endothelium endothelialization delayed, local allergic inflammation, increasing risk of stent thrombosis and other issues. The introduction of drug eluting balloons （DEB） creates a new hope by inhibiting neointimal hyperplasia without increasing the risk of thrombosis. The application of DEB in the treatment of bifurcation lesions is reviewed in this paper.
