目的:探讨经颅多普勒(TCD)与脑干听诱发电位(BAEP)在椎基底动脉供血不足(VBI)诊断中的意义及二者的相关性。方法:对180例临床诊断VBI眩晕的患者及98例对照组进行TCD和BAEP检测。结果:VBI组TCD异常率为80%,X2检测差异有显著意义;BAEP异常率为82.5%,X2检验差异有显著意义。结论:TCD与BAEP检测相结合利于VBI的诊断。
Objective: To investigate the significance of transcranial Doppler (TCD) and brainstem auditory evoked potential (BAEP) in the diagnosis of vertebrobasilar insufficiency (VBI) and their relationship. Methods: TCD and BAEP were detected in 180 patients with VBI vertigo and 98 control subjects. Results: The abnormal rate of TCD in VBI group was 80%, and the difference of X2 test was significant. The abnormal rate of BAEP was 82.5%. The difference of X2 test was significant. Conclusion: The combination of TCD and BAEP is helpful for the diagnosis of VBI.
