[The early postoperative period in patients with tumors of the posterior cranial fossa].

The studies carried out during an early postoperative period in patients with posterior fossa tumors were made to analyse the role of the degree and the level of brain stem damages in formation of cerebral reactions. The three groups of cases were selected in accordance with the course of the postoperative period: 1.1-with exitus letalis (irreversible damages); 1.2-rehabilitation in persistent focal damages; 2-restoration with functional safety of brain stem. Differences of the integral cerebral reactions (the state of consciousness, emotional-affective disorders, awakening state) as well as the brain stem syndromes (formation of pathological systems, reciprocal relations between intact and destroyed brain stem structures) and diencephalic-subcortical syndromes were considered.
