摘要 目的评估Cross BossTM穿透导管(以下简称Cross Boss)在经皮冠状动脉介入治疗(PCI)开通冠状动脉慢性完全闭塞(CTO)病变中应用的有效性与安全性。方法 2015年1~12月20例患者在武汉亚洲心脏病医院因CTO病变行PCI时应用了Cross Boss(Boston Scientific,Natick,MA,USA)穿透导管。回顾性分析所有患者的基线临床资料、冠状动脉造影结果、PCI技术成功率和随访12个月的主要不良心脏事件(MACE)。主要研究终点为PCI技术成功率。结果20例患者共有21处CTO病变入组。应用Cross Boss开通CTO病变,PCI技术成功率为85.7%(18/21),其中2例支架内闭塞型CTO病变全部成功开通,4例既往PCI失败的CTO病变中3例成功开通。应用与未应用Cross Boss的PCI治疗CTO病变的两组间PCI技术成功率差异无统计学意义(85.7%比75.4%,χ2=2.006,P=0.289)。应用Cross Boss的PCI成功患者的平均手术时间为(71±25)min,对比剂使用剂量为(98±22)ml,均显著低于未应用Cross Boss的PCI治疗(均为P<0.05)。围术期PCI相关心肌梗死2例(10.0%)。术后随访12个月,6例发生MACE,总体MACE发生率与未应用Cross Boss的PCI治疗比较,差异无统计学意义(30.0%比16.0%,χ2=2.534,P=0.111)。结论冠状动脉CTO病变PCI术中应用Cross Boss安全、有效,并能减少手术时间和对比剂使用剂量。
