摘要(Abstract)：

目的探讨分支切割球囊预扩张联合分支球囊保护技术在冠状动脉分叉病变单支架置入术中的有效性与安全性。方法顺序入选2015年1月至2016年5月于北京大学人民医院行分支切割球囊预扩张联合分支球囊保护技术的患者32例,共涉及分叉病变32处,均为Medina分型分支开口病变,其中Medina 1,1,1有25例(78.1%)、Medina 0,1,1有5例(15.6%)、Medina 1,0,1有2例(6.2%);分支血管直径≥2.5 mm,采用的切割球囊与分支血管直径比为1∶1。观察患者采取该方法治疗后,主支置入支架过程中分支保护的造影成功率、围术期并发症及主要不良心血管事件发生情况。结果术前血管造影检查示:主支血管直径为(2.9±0.3)mm,狭窄程度为(82.5±8.0)%,病变长度为(19.8±12.8)mm;分支血管直径为(2.5±0.1)mm,开口狭窄程度为(84.5±7.8)%,开口病变长度(4.6±1.1)mm。32例分叉病变患者介入手术造影成功率为100%,未见心肌梗死、分支导丝或球囊断裂、分支夹层和分支丢失等围术期并发症发生,住院期间未见主要不良心血管事件发生。结论在冠状动脉分叉病变单支架策略中,应用分支切割球囊预扩张联合分支球囊保护技术可有效保护分支血管,且操作相对安全。
