subarachnoid haemorrhage

Bleeding over and into the substance of the brain from a ruptured artery lying under the arachnoid layer of the MENINGES. The commonest cause is rupture of a pre-existing berry-like swelling (ANEURYSM) on one of the arteries or bleeding from a tumour-like malformation on an artery. Subarachnoid haemorrhage is the main cause of spontaneous STROKE in young people. There is a sudden severe headache followed by loss of consciousness or other signs of neurological damage. The death rate is high. Treatment is directed to keeping the blood pressure reasonably low, preventing blood vessels from going into spasm and preventing blood clot in an aneurysm from dissolving. Surgery is sometimes appropriate.
