摘　　要：目的:分析经皮冠状动脉介入治疗(PCI)过程中使用夹层重回真腔(DR)术式开通慢性完全闭塞(CTO)病变对患者院内及术后1年结局的影响。方法:连续纳入2018年1月至2020年12月于中国人民解放军空军军医大学第一附属医院心血管内科经冠状动脉造影诊断CTO病变并经PCI治疗成功的815例患者,根据病变开通术式分为DR组(n=239)和非DR组(n=576)。收集患者临床特征、造影特征、术中结果及并发症等资料,使用1:1倾向性评分匹配对临床及造影特征进行校正(两组各208例),比较两组间院内并发症及术后1年主要不良心血管事件(MACE,包括全因死亡和心肌梗死)、临床驱动的靶血管血运重建(TVR)的差异,并采用Cox回归模型分析MACE与TVR的相关危险因素。结果:入选患者平均年龄为(60.9±10.9)岁,男性占87.4%。相比非DR组,DR组靶病变为钝性头端、入口不清、钙化、成角>45°及登陆区不良的比例和J-CTO评分更高(P均<0.05);DR组支架长度和手术时间更长,导丝及对比剂用量更多(P均<0.001)。DR组与非DR组患者院内发生死亡、心肌梗死、穿孔、边支丢失、出血学术研究联合会(BARC)3型以上出血和对比剂肾功能损伤的发生率差异均无统计学意义(P均>0.05),但DR组外周血管并发症发生率更高(P=0.007)。倾向性评分匹配后,DR组与非DR组患者术后1年MACE(2.9%vs.2.4%,log-rank P=0.750)和临床驱动的TVR(5.8%vs.3.9%,log-rank P=0.365)的发生率相当,全因死亡(2.9%vs.1.0%,log-rank P=0.154)和心肌梗死发生率(0.5%vs.1.9%,log-rank P=0.184)差异均无统计学意义。匹配前患者的Cox回归多因素分析结果显示,DR术式对MACE(HR=1.129,95%CI:0.427~2.979,P=0.807)和TVR(HR=0.606,95%CI:0.213~1.722,P=0.347)均无显著影响,左心室射血分数≤40%(HR=2.775,95%CI:1.137~6.774,P=0.025)和残余SYNTAX评分增加(HR=1.089,95%CI:1.032~1.150,P=0.002)是MACE的危险因素,登陆区不良(HR=2.144,95%CI:1.019~4.513,P=0.045)、补救使用正向Objectives:We aimed to compare the impact of dissection and re-entry(DR)recanalizing pattern with non-DR on the in-hospital results and prognostic outcomes of patients treated successfully by percutaneous coronary intervention(PCI)of chronic total occlusion(CTO)and examine the benefit of DR in CTO PCI.Methods:A total of 815 consecutive patients with CTO meeting the inclusion criteria in the Department of Cardiology of the First Affiliated Hospital of PLA Air Force Military Medical University from January 2018 to December 2020 were enrolled and divided into DR group(n=239)and non-DR group(n=576)according to whether DR recanalizing pattern was used in the procedure.The clinical characteristics,coronary angiographic characteristics,procedure results,and complications were collected,and the prognostic outcomes within one year after the procedure were observed.Propensity score matching by the clinical and coronary angiographic characteristics was performed and results were compared with 208 matched patients in each group.The endpoints were the major adverse cardiovascular events(MACE)consisting of all-cause death and myocardial infarction,clinically driven target vessel revascularization(TVR)one year after the procedure,and in-hospital outcomes.Results:The mean age of all patients was(60.9±10.9)years old,and 87.4%were male.As compared with the non-DR group,the proportion of blunt cap,ambiguous,calcification,angle>45°,and diseased landing zone,as well as mean J-CTO score was higher in the DR group(all P<0.05).The mean stent length and median procedure time were longer in the DR group,median guidewires and consumed contrast volume was also higher in the DR group(all P<0.001).Incidence of inhospital death,myocardial infarction,perforation,side branch loss,bleeding of BARC 3rd grade and above,and contrastrelated impairment of renal function were similar between the two groups(all P>0.05).However,peripheral vascular complications occurred more frequently in the DR group(P=0.007).One year after the procedure,the incidence
