[The types and clinical significance of centrogenic reactions occurring during removal of tumors of the posterior cranial fossa].
Specific reactions, the so-called centrogenic reactions or short reflexes, occur in patients when intracranial tumors of the posterior cranial fossa are removed. The authors divide centrogenic reactions into two major groups: types 1 and 2 reactions. The study was based on the analysis of 110 case histories of posterior cranial fossa tumors that were at the extracerebral site. In the study group, centrogenic reactions were recorded in all the patients during neoplasm removal. The findings suggest that these reactions occur mainly in giant tumors of the posterior cranial fossa and decompensation conditions. In patients with type 2 centrogenic reactions, complications and progressive neurological deficit were more frequently observed in the early postoperative period than in those who were had type 1 centrogenic reactions.
