[Surgical removal of a giant intracranial tumor (medulloblastoma) in a child--patient's chances and surgical problems].

A case is presented of an 8-year-old child reoperated on for recurrence of intracranial expansive lesion. Intraoperative cardiac arrest occurred and resuscitation was unsuccessful. The authors analysed the supposed causes of failures and laid stress on problems which may be encountered by the anaesthesiology-neurosurgical team. A number of physiopathological processes occurring here are presented in mathematical form.
