冠状动脉支架治疗冠状动脉开口病变的近远期结果分析

Analysis of Acute and Long term Results of Stenting for Coronary Ostial Lesion

目的：评价冠状动脉支架治疗冠状动脉开口病变的近远期临床效果。方法：对２８例冠状动脉开口病变的病人，按常规标准方法进行冠状动脉支架植入术，并在术后６个月接受临床和（或）冠状动脉造影随访。结果：支架植入的技术和临床成功率均为１００％，无死亡、急性心肌梗塞及急诊冠状动脉旁路移植术并发症。支架植入手术前、后血管直径狭窄程度分别为（８７±９）％与（－２±５）％（Ｐ＜０．０１）；管腔最小开放直径分别为０．４７±０．３１ｍｍ与３．１６±０．３７ｍｍ（Ｐ＜０．０１）。临床随访心绞痛复发率为２０％（４／２０），９例病人接受了冠状动脉造影随访，３例发生了再狭窄。结论：冠状动脉支架植入术治疗冠状动脉开口病变是安全有效的，成功率高且并发症发生率较低。

Objectives:To evaluated acute and long term clinical outcome of stenting in coronary ostial lesion. Methods:Twenty eight consecutive patients (mean age 58 6±8.6 years)were included in the study.Stents were implanted by standard method,clinical and angiographic follow up were performed at 6 months after stenting. Results:Our study showed that both clinical and technical success rate were 100%.No death,acute myocardiol infarction,and emergency coronary artery bypass grafting occurred.Before and after stenting,diameter stenosis were(87± 9 )%vs(-2±5)%,( p <0.01),minimum lumen diameter were 0.47±0.31 mm vs 3.16±0.37 mm,respectively ( p < 0.01).During clinical 6 months follow up,angina recurrence rate was 20%(4 of 20 patients),no death,acute myocardiol infarction,and coronary artery bypass grafting.Coronary angiography was performed in 9 patients at follow up.Restenosis were found in 3 patients. Conclusions:This study suggested that stent implantation for treatment of ostial lesion in coronary artery were safe and effective.It had not only a higher rate of success,but also a significantly lower occurence of complication.
