title: [Study of brainstem auditory evoked potentials in patients with vertebrobasilar blood supply insufficient].
abstract: Brainstem auditory evoked potentials (BAEP) were studied in 93 patients with vertebrobasilar blood supply insufficient. The result showed that the abnormal rate of BAEP was 76.3%, and the rate of abnormality in acute period was much higher than that in recovery period. The BAEP types were classified as inner, brainstem and mixed. The vertigo could be caused by the inner ear ischemia, brainstem or both of them. If there is no improvement of BAEP in long-term follow-up, it suggested that there should be the tiny infarction affecting auditory passage or subclinical blood supply insufficient in brainstem. We believe that BAEP is valuable for the diagnosis of vertebrobasilar blood supply insufficient.
