【摘要】 目的 观察切割球囊治疗支架内再狭窄近期疗效。方法 28例支架内再狭窄患者，男19例，女9例，年龄36~78岁，平均(54±7.2)岁。有高血压病史患者18例，糖尿病10例，高脂血症20例。共有再狭窄病变31处，其中前降支16处，回旋支8处，右冠7处。再狭窄距前次介入治疗时间2~13个月，平均(6.2±3.8)个月。所有患者均有不同程度的心绞痛，采用常规步骤对支架内再狭窄病变行冠状动脉切割球囊扩张术。结果 28例患者31处支架内再狭窄病变中，27例30处病变手术成功，1例失败，成功率96%。术后心绞痛症状明显减轻或消失，所有患者无并发症，失败1例原因为病变血管迂曲，球囊不能通过病变。1例术后2个月出现心绞痛，选择外科搭桥术。结论 切割球囊治疗支架内再狭窄有良好近期疗效。远期疗效有待更多病例证实。

    【Abstract 】 Objective To observe the short-term results of cutting balloon angioplasty(CBA) in therapy of in-stent restenosis.Methods There were 28 in-stent restenosis patients in the group (male:19;female:9;age between 36 and 78,mean age 54±7.2 year),with history of 18 hypertention,10 diabetes mellitus and 20 hyperlipidemia.Altogether 31 lesons enrolled the study.The average time from previous intervention was 2~13(6.2±3.8) months.All patients were having angina pectoris of different degree.CBA was performed under routine processure.Results 31 leisions in 28 patients were treated successfully out of 30 lesions in 27 patients.Only one failed,with a successful rate of 96%.The symptoms lightened or vanished significantly after operation, with no complications in all patients.One failed because the lesion was so tortuous that the balloon couldn’t pass through.Angina pectoris recurred in one patient after 2 months and underwent bypass surgery.Conclusion CBA is a safe and efficient technique with a high successful rate and satisfied short-term results in the treatment of in-stent restenosis.As to the forward results,more cases are needed to affirm further. ......
