[Lateralization of secondary lesions of the brain stem in stroke by the method of short-latency auditory evoked potentials].
Twenty-seven patients with acute cerebral circulation disorders (ACCD) in large hemispheres and 4 patients with ACCD in the cerebellum were examined by means of short-latent acoustic evoked potentials (SAEP). The signs of the secondary stem syndrome were recorded in the neurological status of all the patients. Computer-aided tomography discovered displacement of the median structures of varying degree and deformation of cisternal spaces of the stem. The data obtained allowed a conclusion about a possibility of lateralization of the side of a greater injury to the stem by means of SAEP. As a rule, it was made ipsilaterally to the supratentorial focus. Provided the focus is seated subtentorially, a special pattern of SAEP may occur, namely primary changes in 1-3 components till complete disappearance of the evoked response.
