血管内超声在冠状动脉慢性完全闭塞病变行经皮冠状动脉介入治疗中的再评价

摘要(Abstract)：
<正>冠状动脉慢性完全闭塞病变(chronic total occlusion,CTO)行经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)成功率低,并发症发生率高,因而被认为是目前PCI领域最大的挑战之一~([1])。导引钢丝能否通过CTO是PCI成败的关键,主要取决于术者的技术和经验。冠状动脉造影是指导导引钢丝通过CTO的最主要方法,通过双侧造影或侧支血管显影确定导引钢丝位于血管远段的位置,有助于确认导引钢丝是否位于血管真腔。然而造影有时会存在误判,且无法确认导引钢丝在闭塞段
