title: Astrocytic reaction in long-term resuscitation.
abstract: The brain of 34 subjects who died after prolonged resuscitation (more than 20 days) were studied in order to evaluate the possibility of discriminating original cerebral injuries from changes caused by prolonged resuscitation. We focused our attention on the astrocytic reaction and its relationship to the associated lesions. Twelve of the 34 cases showed astrocytosis picture. Of these 5 were anisomorphic and 7 isomorphic. From the analysis of the various morphological findings, taking into account an individual's clinical history, we can conclude that isomorphic astrocytosis is a typical morphological reaction related to resuscitation duration and it is the result of a slow, gradual neuronal degeneration induced by chronic hypoxia. Anisomorphic astrocytosis, on the other hand, can be an indicator of acute and focal cerebral lesion.
