Pathological finding of auditory evoked potentials in patients with vertebral artery hypoplasia associated with posterior circulation stroke

Abstract

The aim of the paper was to determine clinical significance of pathological finding and characteristics of auditory evoked potentials (AEP) in patients with posterior circulation stroke caused by vertebral artery hypoplasia (VAH). The study enrolled 71 patients, 31 of them had posterior circulation stroke. The results of the examinations showed that pathological AEP finding was statistically significantly correlated with posterior circulation stroke (PCS) finding. Changes in AEP amplitude presented a prominent feature of stroke caused by vertebral artery hypoplasia and require further clinical investigations.
