Extract
- Subarachnoid haemorrhage (SAH) should be suspected however slight the symptoms, and the diagnosis confirmed with an urgent CT scan.
- SAH is an acute systemic illness requiring neurointensive care.
- The patient should be transferred as an emergency case to an appropriate hospital for neurosurgical treatment, neurointensive care and cerebral angiography.
- A ruptured intracranial aneurysm must be closed by microsurgical clipping or an endovascular approach during the acute phase to prevent rebleeding.
- Patients with SAH often have sequelae in the form of neurological, psychiatric and psychosocial problems.
- Even an initially deeply unconscious patient with SAH may still have a favourable prognosis and must be taken to intensive care to assess the situation.
- In a situation with no prospect of recovery, the possibility of brain death and organ donation must be kept in mind.
