目的:评价在分支处病变应用“crush”支架技术置入雷帕霉素或紫杉醇药物洗脱支架后的远期疗效。背景:当前认为,对分支处病变处理最好的方法是在主干血管置入裸金属支架或药物洗脱支架,侧支血管应用球囊扩张,但当侧支血管病变广泛也需置入支架时这种方法则具有限制性。应用“cru PURPOSE: To evaluate the long-term efficacy of “crush” stent implantation in ramification or paclitaxel-eluting stents at diseased branches. BACKGROUND: It is currently believed that the best way to treat branches of the lesion is to place bare metal stents or drug-eluting stents in the main blood vessels and balloon dilatation of the collateral vessels, but when extensive collateral vessel disease is also required for stent placement This method is restrictive. Application "cru
