摘　　要：目的观察颅多普勒(TCD)和磁共振血管成像(MRA)在缺血性脑卒中患者静脉溶栓治疗(IVT)后诊断MCA闭塞后再通的一致性。方法IVT后24 h内对入组患者进行TCD和MRA检查,并对MCA的再通情况进行配对等级资料的Kappa一致性检验。结果TCD和MRA对于患者IVT后血流分级的诊断一致性良好(K=0.852,P=0.000)。结论TCD在对于血管狭窄及闭塞的诊断上准确率高,便于动态观察,在IVT诊疗过程中能得到广泛应用。Objective To observe the consistency of TCD and MRA in the diagnosis of MCA recanalization after IVT in patients with ischemic stroke.Methods TCD and MRA were performed within 24 hours after IVT,and Kappa consistency test was performed on the data of MCA recanalization by matching grade.Results The results of TCD and MRA were consistent in the diagnosis of blood flow grading after IVT(K=0.852,P=0.000).Conclusion TCD has a high accuracy rate in the diagnosis of vascular stenosis and occlusion,and is convenient for bedside operation and dynamic observation.It can be widely used in the diagnosis and treatment of IVT.
