We present an overview on the impact of evoked potentials in diagnosis of ischemic brainstem lesions. Brainstem auditory evoked potentials and somatosensory evoked potentials depict abnormalities, whereas visual evoked potentials are normal in most cases. In patients with basilar artery thrombosis and primary pontine hemorrhage these evoked potentials are mostly abnormal and can indicate the location of the lesion. Furthermore, they are of prognostic value. Whether evoked potentials are abnormal in strokes with branch occlusion of the basilar artery, depends on the location of the infarction. In infarctions of the basis pontis BAEP and SEP may be normal. Hemiparesis in brainstem strokes are associated with abnormalities in transcranial magnetic stimulation. However, no further evaluation of the level of the pyramidal tract lesion is possible by this method. During fibrinolytic therapy of basilar artery thrombosis a continuous monitoring is possible by means of BAEP. Thus, information can be obtained that is not available from neurological examination of the patient under sedative drugs.
我们对诱发电位在缺血性脑干病变诊断中的作用进行综述。脑干听觉诱发电位和体感诱发电位可显示异常，而视觉诱发电位在大多数情况下正常。在基底动脉血栓形成和原发性脑桥出血患者中，这些诱发电位大多异常，可提示病变部位。此外，它们还具有预后价值。基底动脉分支闭塞性卒中时诱发电位是否异常取决于梗死部位。脑桥基底部梗死时，脑干听觉诱发电位（BAEP）和体感诱发电位（SEP）可能正常。脑干卒中的偏瘫与经颅磁刺激异常有关。然而，通过这种方法无法进一步评估锥体束病变的水平。在基底动脉血栓形成的纤维蛋白溶解治疗期间，可通过BAEP进行连续监测。因此，可以获得在使用镇静药物的患者神经检查中无法获得的信息。
