目的：研究脑干听觉诱发电位（ＢＡＥＰ）对椎基底动脉供血不足（ＶＢＩ）患者的诊断及康复评定价值。方法：对８０例ＶＢＩ患者（疾病组）和３６例健康人（对照组）行ＢＡＥＰ检查，测量Ｉ～Ｖ各波峰潜伏期（ＰＬ）和峰间潜伏期（ＩＰＬ），采用ｔ检验对两组检查结果进行比较并分析疾病组异常表现。结果：疾病组Ⅲ－ＶＩＰＬ、Ⅲ－Ｖ／Ｉ－Ⅲ比值（Ｐ＜０．００１）以及Ｖ波ＰＬ、Ⅲ－ＶＩＰＬ（Ｐ＜０．０５）均较对照组增大。ＢＡＥＰ异常率为８１％，其中脑干型异常占６２％。各指标中，Ⅲ－Ｖ／Ｉ－Ⅲ＞１最常见，占４６％。结论：本组资料提示ＶＢＩ患者以桥脑中上部缺血较重，Ⅲ－Ｖ／Ｉ－Ⅲ比值是反映脑干缺血的敏感指标，ＢＡＥＰ为ＶＢＩ的诊断及康复评定提供了有价值的依据，值得深入研究。
Objective: To evaluate the diagnostic and rehabilitation evaluation of brainstem auditory evoked potential (BAEP) in patients with vertebrobasilar insufficiency (VBI). Methods: Eighty patients with VBI (disease group) and 36 healthy people (control group) underwent BAEP examination. The peak latency (PL) and peak latency (IPL) of each peak in I ~ V were measured. To compare and analyze the abnormal performance of the disease group. Results: The ratio of Ⅲ-VIPL, Ⅲ-V / I-Ⅲ (P <0.001) and V-wave PL, Ⅲ-VIPL (P <0.05) in disease group were higher than those in control group. The abnormal rate of BAEP was 81%, of which brainstem abnormalities accounted for 62%. In each index, Ⅲ-V / I-Ⅲ> 1 is the most common, accounting for 46%. CONCLUSIONS: The data in this group suggest that the mid-upper ischemic pontine is heavier in VBI patients and the Ⅲ-V / I-Ⅲ ratio is a sensitive indicator of brainstem ischemia. BAEP provides a valuable basis for the diagnosis and rehabilitation evaluation of VBI , Worth in-depth study.
