BAEP对青年人脑干早期受损的诊断作用

Diagnostic value of BAEP in early brainstem injury with young people

目的：探讨脑干听觉诱发电位（BAEP）检测在诊断青年人脑干早期受损中的作用。方法：收集49例初诊时影像学结果正常而BAEP检测结果异常的青年患者的临床资料，对初诊时、3～6个月复查时的BAEP检测结果进行分析。结果：①BAEP检测复查结果显示：5例（10%）恢复正常，9例（18％）好转，31例（63％）无变化，4例（8％）加重；②4例BAEP加重患者复查CT结果显示2例脑干腔梗，2例正常；③2例BAEP检测结果加重并CT结果改变者均为有高血压、高血脂病、且家族史有不良生活习惯者。结论：BAEP检测结果作为脑干早期受损的较敏感指标．提示在某些病例中或更能早于影像学反映脑干早期受损状态；脑干早期受损病例的BAEP检测异常结果在短时间内不易恢复。

Objective： To investigate the diagnostic value of brainstem auditory evoked potential （BAEP） in young people with eary brainstem injury. Methods：49 young patients with abnormal BAEP and normal brain imaging were enrolled in the study. The BAEP results for the first time and 3 ~ 6 months laler were analyzed. Resultsi： （1） BAEP of the patiants was examined as follow.. 5 patients （ 10 % ） returned to normal ; 9 patients（18%） were improved ; 31 patients（63 % ） remained unchanged 4 pat!ents（8% ） were deteriorated ; （2）Of 4 deteriorated patients, head CT rescan showed brainstem lacunar infarction in 2 pateints and normal in 2 patients; （3）hypertension, hyperlipid, family history and bad lifestyle habits were found in 2 patients with deteriorated BAEP and abnormal head CT. Conclusion： BAEP can be used as a sensitive index for early brainstem injury, because it can find early brainstem injury prior to the imaging in some cases. Abnormal BAEP in patients with early brainstem injury is difficult to recover for a short time.
