title: [Clinico-physiologic analysis of the effect of decompressing the cerebrospinal fluid system in children with hydrocephalus].
abstract: Changes in vascular tonicity and blood filling in the brain were studied in 26 children with occlusive hydrocephalus during ventricular punctures and following surgical elimination of the occlusion. The nature of the reactive changes in the tonicity and blood filling of the cerebral and peripheral vessels was found to be different in response to the draining of the CSF system depending on the level of thebrain lesion. Following ventricular punctures with CSF draining the majority of the examined demonstrated a normalization of their elevated tonicity of the cerebral vessels and a disappearance of hampered venous drainage. The dynamics of the vascular responses developing under the effect of dehydration agents is characterized by the maximum response 30-50 min following the administration of the drug and by a gradual restoration of the initial state some 2-2 1/2 hours later.
