准分子激光冠状动脉成形术在慢性完全闭塞性病变中的应用

Application of Excimer Laser Coronary Atherectomy for Treating the Patients With Coronary Chronic Total Occlusion

目的:观察准分子激光冠状动脉成形术(ELCA)在冠状动脉慢性完全性闭塞(CTO)病变中应用的安全性和有效性。方法:总结自2015-01至2016-11在阜外医院冠心病中心应用ELCA治疗的3例CTO病变患者,导引钢丝在对侧冠状动脉造影指引下通过闭塞段病变,应用ELCA治疗后进行药物洗脱支架置入。观察手术成功率及并发症,并随访主要心脏不良事件(MACE)发生情况。结果:3例患者ELCA器械操作全部成功、介入治疗全部成功。术中无1例发生血管夹层、穿孔、慢血流及血栓形成,随访期间无1例发生心绞痛、心肌梗死、靶病变再次血运重建及死亡。结论:应用ELCA联合药物洗脱支架治疗CTO是安全有效的。

Objective： To observe the safety and efifcacy of excimer laser coronary atherectomy （ELCA） for treating the patients with coronary chronic total occlusion （CTO）. Methods： A total of 3 coronary CTO patients treated by ELCA in our hospital from 2015-01 to 2016-11 were analyzed. The patients received guide steel wire gone through occlusion segment under the guidance of offside coronary angiography; drug-eluting stent implantation was conducted after ELCA treatment. The operative success rate with complication was observed and the occurrence of MACE was followed-up. Results： The device performing and interventional therapy were succeed in all 3 patients. No coronary dissection, perforation, slow relfow and thrombosis were occurred during the operation; no angina, myocardial infarction, target vessel revascularization and death were observed by follow-up study. Conclusion： Application of ELCA combining drug-eluting stent implantation was safe and effective for treating the patients with coronary CTO.
