[Visual evoked potentials in disorders of the cerebral circulation].
Visual evoked potentials were analysed in 15 patients before and after operations performed in the acute and cold periods of rupture of cerebral aneurysms. The analysis made it possible to identify the regions of the disturbed latency and shape of the potentials. The location of the aneurysm determines the site of the region of impairment of the visual evoked potentials, whose area correlates with the severity of the patients' condition in the acute period. Diminution of the region of impairment of the evoked potentials was more manifest in patients who were operated on in the acute period of rupture of the aneurysm than in those who underwent operation in the cold period.
