[Auditory brainstem response in the anterior inferior cerebellar artery insufficiency].
The purpose of this study was to determine the effects of vascular occlusion on the cochlear blood flow and auditory brainstem response (ABR) in the cat basilar artery system. Any occlusion in the basilar, anterior inferior cerebellar, or internal auditory arteries had chances of decreasing the cochlear blood flow, in which case the extent of the depression of the waves I and II of ABR was proportional to the blood flow decrease. This results suggests attention should be payed to the ischemic cochlear involvement in evaluation of the brainstem pathology using ABR.
