摘　　要：目的分析血管内超声在冠状动脉慢性完全闭塞(chronic total occlusion,CTO)患者经皮冠状动脉介入治疗(percu-taneous coronary intervention,PCI)术中的应用和安全性。方法回顾性分析2016年3月至2017年6月本院收治的65例行PCI的CTO患者的临床资料,将35例行血管内超声引导的患者纳入观察组,将30例行冠状动脉造影引导的患者纳入对照组。比较两组患者围术期情况、并发症发生率和PCI失败原因。结果观察组患者手术时间、支架长度均显著长于对照组(均P<0.05),PCI成功率显著高于对照组(P<0.05),并发症发生率显著低于对照组(P<0.05)。在PCI失败患者中,观察组入假腔后未能入真腔发生率明显高于对照组(P<0.05),入口即入假腔的发生率显著低于对照组(P<0.05),两组逆向失败发生率比较差异无统计学意义(P>0.05)。结论血管内超声引导可提高CTO患者PCI成功率,降低患者并发症发生率,安全性高。Objective To analyze the application and safety of intravascular ultrasound in patients with chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI). Method Retrospectively analyzed the clinical data of 65 patients with CTO in our hospital from March 2016 to June 2017. Patients with intravascular ultrasound were included in observation group (35 cases), and patients with coronary arteriography were included in control group (30 cases). The perioperative status, incidence of complications and causes of PCI failure were compared between the two groups. Result The operation time and stent length of observation group were significantly longer than those of control group (all P < 0.05), the success rate of PCI was significantly higher than that of control group (P < 0.05), and the incidence of complications was significantly lower than that of control group (P < 0.05). In patients with PCI failure, the incidence of failure to enter the true cavity in observation group was significantly higher than that in control group (P < 0.05), and the incidence of entering the false cavity at the entrance was significantly lower than that control group (P < 0.05). There was no significant difference in the incidence of reverse failure between the two groups (P > 0.05). Conclusion Intravascular ultrasound guidance can improve the success rate of PCI in CTO patients and reduce the incidence of complications, it has high safety.
