摘　　要：目的探究采用管腔扩张微导管(corsair微导管)辅助正向夹层再进入(ADR)治疗冠心病合并冠状动脉慢性完全闭塞(CTO)的临床效果。方法回顾性选取2019年2月—2021年3月于广西梧州市工人医院采用ADR技术治疗的冠心病合并CTO患者93例,根据其是否应用corsair微导管联合新型CTO病变专用导丝辅助治疗分为corsair微导管辅助组(n=46例)和无corsair微导管辅助组(n=47例)。收集两组病例数据,比较两组造影时间、对比剂用量、手术时间、手术成功率及术后并发症发生率;对比两组患者术后1年主要不良心血管事件发生率和病死率。结果corsair微导管辅助组造影时间及手术时间均短于无corsair微导管辅助组(P<0.001),对比剂用量少于无corsair微导管辅助组(P<0.001);corsair微导管辅助组术中操作成功41例(89.13%),高于无corsair微导管辅助组的32例(68.09%)(χ^(2)=6.100,P=0.014);corsair微导管辅助组术后总并发症发生率为10.87%,低于无corsair微导管辅助组的38.30%(χ^(2)=9.395,P=0.002);corsair微导管辅助组1年主要心血管不良事件发生率为4.35%,低于无corsair微导管辅助组的19.15%(χ^(2)=4.883,P=0.027),两组1年病死率比较差异无统计学意义(P=1.000)。结论corsair微导管辅助ADR技术治疗冠心病合并CTO患者的有效性和安全性更高。Objective To investigate the clinical effect of lumen dilated microcatheter(corsair microcatheters)assisted forward dissection re-entry(ADR)in the treatment of coronary heart disease complicated with chronic complete occlusion(CTO)of coronary arteries.Methods A total of 93 patients with coronary heart disease and CTO who underwent ADR technology in Wuzhou Workers'Hospital from February 2019 to March 2021 were retrospectively selected.All patients were divided into corsair microcatheter assisted group(n=46 cases)and corsair-free microcatheter assisted group(n=47 cases)according to whether they were treated with corsair microcatheters combined with special guide wire auxiliary therapy for new CTO lesions.Data from two sets of cases were collected,imaging time,contrast agent dosage,surgical time,surgical success rate,and postoperative complication incidence between the two groups were compared.In addition,the incidence and mortality of major adverse cardiovascular events within 1 year after surgery between the two groups were compared.Results The contrast time and surgery time of the corsair microcatheter assisted group were shorter than those of the corsair-free microcatheter assisted group(P<0.001),and the contrast agent dosage in the corsair microcatheter assisted group was less than that in the corsair-free microcatheter assisted group(P<0.001);41 cases(89.13%)were successfully operated in the corsair microcatheter assisted group,more than those(32 cases[68.09%])in the non-corsair microcatheter assisted group(χ^(2)=6.100,P=0.014);the total postoperative complication rate in the corsair microcatheter assisted group was 10.87%,which was lower than that in the corsair-free microcatheter assisted group(38.30%)(χ^(2)=9.395,P=0.002);the incidence of major adverse cardiovascular events within 1 year in the corsair microcatheter assist group was 4.35%,which was significantly lower than that in the corsair-free microcatheter assist group(19.15%)(χ^(2)=4.883,P=0.027),and there was no statistically significant differenc
