[The role of brain stem lesions in cerebral circulatory disorders accompanying severe cranio-cerebral injuries].

Clinical and anatomical comparisons were undertaken in 23 cases of mortality due to severe craniocerebral injuries. The set of clinical examinations included circulation and brain gas exchange studies. Cerebral circulatory hypoxy was revealed in all the patients, but in cases of its compensated form all signs of brain stem injury were lacking, while in cases of its non-compensated form foci of brain stem injury could be revealed at autopsy. Timely elimination of brain stem compression in cases of its anatomic integrity preserved helps to convert the non-compensated form of cerebral circulatory hypoxy into its compensated form.
