冠状动脉分叉病变特点、分型和治疗策略

Definition,Classification and Treatments of Bifurcation Lesions

分叉病变始终是冠状动脉介入治疗的一个难点,尽管药物洗脱支架减少了介入术后主支的再狭窄,但分支血管的术中急性闭塞风险和术后再狭窄和支架内血栓问题仍值得关注。现回顾冠状动脉分叉病变的定义、分类和各种治疗方法,以期对冠状动脉介入治疗有一个较全面的认识。

Treatment of coronary bifurcation lesions represents a challenging area in interventional cardiology. The introduction of drug-eluting stents reduced restenosis in the main branch . However, side branch risk of acute closure, restenosis at the ostium of the side branch and stent thrombosis remain the problems. We review the definition, classification and treatment strategies of bifurcation lesions in order to give an insight in this erea.
