摘要
目的评价脑干听觉诱发电位(BAEP)及经颅多普勒(TCD)检查的临床价值。方法对124例经临床确诊的后循环缺血患者依据临床症状及CT、MRI检查结果分为梗死亚组(53例)和非梗死亚组(71例),均进行BAEP及经颅多普勒检查,并与健康对照组(60例)进行对比。结果 124例后循环缺血患者中,BAEP异常113例,异常率91.11%。与对照组比较,后循环缺血患者的Ⅴ波峰潜伏期和Ⅲ～Ⅴ波的峰间潜伏期均延长,差异有统计学意义(P<0.05)。梗死亚组与非梗死亚组比较,Ⅴ波峰潜伏期、Ⅲ～Ⅴ波峰间潜伏期亦延长,差异有统计学意义(P<0.05)。124例后循环缺血患者中,TCD异常79例,异常率63.7%,其中梗死亚组异常率(77.3%)高于非梗死亚组(53.5%),差异有统计学意义(P<0.05)。结论联合应用BAEP和TCD可为后循环缺血的病情评估提供重要的参考。
Objective To assess the clinical value of the evaluation of brainstem auditory evoked potential（BAEP）and transcra nial doppler（TCD）. Methods 124 patients with posterior circulation ischemia（PCI） were divided into the infarct group（53 cases） and the non-infarct group（71 cases）, and compared with 60 health controls. All patients were examined by TCD and BAEP. Results In the 124 cases of posterior circulation ischemia patients,BAEP was abnormal in 113 cases, and the abnormal rate was 91.11%. Compared with control group,posterior circulation ischemia in patients with V peak latency and the Ⅲ～Ⅴ peak to peak incubation period extended,the difference was statistically significant（P〈0.05）. Infarction subgroup and the non-infarcted subgroup V peak latency, Ⅲ～Ⅴ peak between the incubation period extended,the difference was statistically significant（P〈0.05）. In the 124 cases of posterior circulation ischemia patients, TCD was abnormal in 79 cases, and the abnormal rate was 63.7%, and infarction sub grouprs abnormality rate（77.3 %） was higher than the non-infarcted subgroup （53.5 %）, the difference was statistically significant （P〈0.05）. Conclusion Combined examination of TCD and BAEP contributes to the early diagnosis,assessment and prognosis for PCI.
