经颅多普勒和脑电图诊断短暂性脑缺血发作60例分析

Transcranial Doppler and EEG diagnosis in 60 cases with transient ischemic attack

目的:对经颅多普勒和脑电图诊断短暂性脑缺血发作进行比较。方法:60例短暂性脑缺血发作患者同时进行经颅多普勒及脑电图检查,对比分析两种检查手段的阳性率。结果:脑电图轻度异常31例,中度异常5例,重度异常1例,异常率61.67%;经颅多普勒检查发现血流速度增快、血管狭窄29例,流速降低10例,血管狭窄合并流速降低8例,异常率78.33%,两种检查异常率比较有显著性差异(P<0.05),经颅多普勒阳性率明显高于脑电图。结论:经颅多普勒诊断短暂性脑缺血比脑电图更为敏感,阳性率更高,是一种简单、快速、准确的检查手段,值得在临床中推广。

Objective：To compare and analyze the use of transcranial Doppler and EEG in cases with transient cerebral ischemic attack. Methods：60 cases with transient cerebral ischemic attack were checked by both transcranial Doppler and EEG examination to make the comparative analysis of the positive rates of two examination methods. Results：The EEG examination, mildly abnormal in 31 cases, 5 cases of moderate abnormality, 1 case of severe abnormality, 61.67% for the abnormal rate; 29 cases of vascular stenosis were found out by transcranial Doppler examination, 10 cases for reduction of the flow rate, and 8 cases Of both vascular stenosis and reduction of the flow rate,the abnormal rate came to 78.33 ~. The abnormal rate between the two methods was significantly dif- ferent（P〈0.05）. The positive rate of transcranial Doppler was conspicuously higher than that of EEG examination. Conclusion： Comparing with the EEG, the diagnosis of transcranial Doppler is more sensitive as well as higher positive rate, which is worth promoting in the clinical work because of it＇s simple,fast and accurate screening advantages.
