目的：探讨脑干听觉诱发电位（ＢＡＥＰ）在椎基底动脉供血不足（ＶＢＩ）诊断中的意义。方法：对１０９例ＶＢＩ患者做常规ＢＡＥＰ检查，并对其结果按年龄、病程进行分析。结果：１０９例中异常８１例（７４３％），异常表现为各主波的潜伏期和波间期延长。其中病程＜２年者异常率为４０６％（１３／３２例），２～５年者为８７８％（３６／４１），＞５年者为８８９％（３２／３６）。结论：ＶＢＩ患者的ＢＡＥＰ异常率有随病程延长而增高的倾向。ＢＡＥＰ对ＶＢＩ缓解期病例的诊断有一定参考意义。
Objective: To explore the significance of brainstem auditory evoked potential (BAEP) in the diagnosis of vertebrobasilar insufficiency (VBI). Methods: 109 patients with VBI routine BAEP examination, and its results by age and duration of the analysis. Results: Of the 109 cases, 81 cases were abnormal (743%). The abnormalities were the latency and wave interval prolongation. Among them, the abnormality rate was 40.6% (13/32) in 2 years, 87.8% (36/41) in 2- 5 years, 88.9% (32/36) in 5 years, . Conclusion: The abnormal rate of BAEP in VBI patients tends to increase with the duration of the disease. BAEP has certain reference value for the diagnosis of VBI remission cases.
