冠状动脉闭塞病变介入治疗的临床分析

Clinical investigation of revascularization for coronary artery occlusion

目的 探讨冠状动脉闭塞病变介入治疗成功率的影响因素。方法 对 4 5例行介入治疗的冠状动脉闭塞患者进行分析。结果 4 5例患者的 4 7支闭塞病变经介入治疗后 37支开通 ,病变治疗成功率 78.7% ,病例治疗成功率 80 % (36 /45 )。血管闭塞时间 1个月内的病变治疗成功率为 96 % ,1～ 3个月的成功率为 70 % ,大于 3个月的成功率为 5 0 %。A型解剖性病变的成功率为 80 .9% ,B型解剖性病变的成功率为 6 4 .3% ,功能性闭塞病变成功率为91.7%。

Objective To study the factors related to primary success and failure of angioplasty of coronary artery occlusion. Methods The result in 45 patients after coronary angioplasty of the occlusion was analysed. Result Thirty-seven occluded branches were revascularized in 45 patients with 47 occlusions, the lesion success rate was 78.7% while the case success rate was 80% (36/45). The lesion success rate was 96% in patients with an occlusion duration of ≤1 month. The lesion success rate was 70% in patients with an occlusion duration of ≤3 month. The lesion success rate was 50% in patients with an occlusion duration of >3 month. The lesion success rate was 80.9% in patients with the type A anatomical occlusion. The lesion success rate was 64.3% in patients with the type B anatomical occlusions. The lesion success rate was 91.7% in patients with the functional occlusions. Conclusion The occluded time and lesion morphology were important factors that predicted angiographic and clinical success in angioplasty of the occlusions.
