[Contribution to the neuropathology of stereotactic brain-operations and their fatal complications (author's transl)].

Report on the neuropathology of 6 fatal cases in 150 stereotactic operations, performed on 135 patients from 1960 to February 1978. The deceased had a hyperkinesis and a severe Parkinson's disease in 3 cases each. Only two of them had died of a complicating intracranial extracerebral haemorrhage immediately after the stereotactic operation. In our own material the longest survival time after operation was about 3 years. Biochemical and biothermical reactions and situations basing on thermocoagulation are dealt with in particular.
