[Intracranial haemorrhage. A reason for delayed awakening after general anaesthesia].

Delayed awakening after general anaesthesia is in the majority of cases due to prolonged effects of anaesthetic drugs. However, intracerebral processes are also associated with disturbances of consciousness. Here, we report a case of a female patient who developed an intracerebral haemorrhage because of an arteriovenous malformation during routine surgery. This shows that in the case of delayed awakening after general anaesthesia the possibility of an intracerebral process should be considered early even after routine surgery.
