title: [Subarachnoid Hemorrhage and Isolated Brainstem Death].
abstract: BACKGROUND
  Worldwide there are differences in the procedure of determining brain death. An irreversible loss of all brain functions, including cerebrum, cerebellum and brainstem is mandatory for the diagnosis of brain death in Germany. On the basis of a case report some important aspects of the new recommendations of the German guidelines are discussed.
  
  
  METHODS
  We present the case of a 41-year old patient who was admitted to our clinic due to acute subarachnoid hemorrhage (SAH). Angiography revealed an aneurysm of the posterior inferior cerebellar artery. The patient was comatose without any brainstem reflexes and showed apnoea. However, on day 3, EEG showed alpha activity as a sign of residual cortical function. We diagnosed an isolated brainstem death. The next day EEG was isoelectric and brain death was confirmed.
  
  
  CONCLUSIONS
  The diagnosis of isolated brainstem death does not allow a confirmation of death in Germany. Our case presents a primary infratentorial brain damage mandating additional confirmatory tests.
