[The hypothalamus in neurosurgical patients (pathologo-anatomic and clinico-electroencephalographic correlations)].

Only a third of the cases who have neurosurgical abnormality has been found to develop irreversible hypothalamus affections caused by tumor growth, hemorrhages, and ischemic infarcts. Microcirculatory abnormalities made up three typical morphological variants, viz. venous congestion, impaired rheological and coagulative properties of blood, and anemia in the vasculature predominantly occur in the other cases. Acute bilateral destruction in the medial segments of the hypothalamus corresponds to its profound functional inhibition. As its morphological substrate, sharp irritation of the hypothalamus (the diencephalic and catabolic syndrome has widespread rheological and coagulative abnormalities in its structures associated with largely reversible dystrophic changes in nerve cells.
