[Guidelines for pathomorphological study of the brain of fetuses and neonatal infants with hydrocephalus].

Guidelines are proposed to study the brain of fetuses and neonatal infants with hydrocephalus. Some of them (evaluation of the rate of gyrification and its correspondence to the gestational period of the fetus, by visualizing the cerebral hemisphic surface; perfusion of cerebral vessels by the Karaganov fixator) are original, informative, and developed by the authors and are successfully used in the scientific and practical work of pathologists.
