title: [Value of the de Kleyn symptom in diagnosing vertebro-basilar insufficiency].
abstract: A total of 540 cases with cerebral vascular disorders examined otoneurologically were analyzed. The observed patients were treated in the Research Institute of Neurology. In 62 patients (11,5%) the De Klein symptom was detected. A comparison of the otoneurological rheoencephalographic and neurological symptomatology gives grounds to evaluate the De Klein symptom, encountered in different degrees of circulatory insufficiency in the vertebro-basillar system, as one of the early signs of vascular decompensation in initial forms of cerebro-vascular insufficiency, marking its diagnostic significance.
