冠状动脉开口病变切割球囊成形术的预后

目的　评价切割球囊冠状动脉腔内成行术治疗开口病变的安全性及疗效。方法　 5 2例冠心病患者 5 2处开口病变行切割球囊扩张治疗 ,对其进行分析并短期临床随访。结果 5 2例病变血管直接切割球囊扩张治疗成功率98% ,切割球囊扩张后残余狭窄程度 (18.2± 17.1) % ,术终残余狭窄程度 (16 .8± 11.5 ) %。 1例对角支扩张后出现严重内膜撕裂安放支架 ,无急性闭塞、急诊冠状动脉旁路移植术及急性心肌梗死发生。随访期间无心脏事件发生。结论　切割球囊冠状动脉腔内成行术治疗冠状动脉开口病变安全、疗效良好。

Prognosis of patints with coronary artery disease following coronary cutting balloon in ostial lesions

Objective To evaluate the safety and efficacy and short-term results of cutting balloon (CB) coronary angioplasty to ostial lesion.Methods CB angioplasty was performed on 52 lesion in 52 patients. ResultsThe overall success rates of the primary cutting balloon angioplasty without predilatation were 98%.Residual stenosis was(%)16.8 11.5 after cutting balloon angioplasty.One case with Diagonal Branches ostial lesion appeared dissection stent was implanted at Diagonal Branches.No abrupt coronary closure,emergency by pass surgery and acute myocardial infarction occurred.No further cardiac events at follow-up.ConclusionCB angioplasty to ostial lesion is a safe and efficient technique with a high succsess rate and satisfactory short-term results.
