摘　　要：目的探讨血管内超声指导下冠状动脉旋磨术联合药物支架治疗严重钙化病变的疗效及安全性。方法回顾性分析血管内超声指导下行冠状动脉旋磨术和支架植入术治疗17例21处严重钙化病变。观察手术成功率、术后主要心血管事件(包括心源性死亡、心肌梗死、靶病变血运重建)的发生率。结果 17例患者手术成功率为100%。术中均无严重并发症(包括心源性死亡、Q波心肌梗死、急诊冠状动脉旁路移植术)发生。所有患者随访1年,有2例再发心绞痛,无主要心血管事件发生。6例患者复查冠状动脉造影,有2例出现支架内再狭窄30%。结论血管内超声指导下冠状动脉旋磨术联合药物支架治疗严重钙化病变手术成功率高,是治疗严重钙化病变安全、有效的方法。Objective To evaluate the efficiency and safety of coronary atherectomy combined with drug - eluting stents in curing severe calcified lesions. Methods Retrospectively analyzed the datas 17 patients （21 severe calcified lesions） who suffered from calcified lesions and received coronary rotational atherectomy under intravascular ultrasound guidance and stent implantation. Observe the success rate of surgery, incidence of major postoperative cardiovascular events （cardiac death, myocardial infarction, revascularization in target lesion）. Results All the 17 surgeries were success and the rate was 100%. There were no serious intra - operative complications occurred （cardiac death, Q -wave myocardial infarction, emergency coronary artery bypass grafting）. All patients were followed up for 1 year, there were two cases of recurrent angina, none cardiovascular events. 6 patients received coronary angiography again, 2 restenosis occurred. Conclusions Coronary rotational atherectomy under intravascular ultrasound guidance combined with drug - eluting stents is safe and effective for severe calcified lesions.
