Aneurysmal subarachnoid haemorrhage

Spontaneous subarachnoid haemorrhage accounts for only 3–4% of all stroke but the consequences can be devastating. In the present review article, we review the epidemiology, clinical features, investigations and management philosophy in patients with aneurysmal subarachnoid haemorrhage. Oral nimodipine, aneurysmal occlusion and advances in neurointensive care are the keys to improve neurological outcome in patients after aneurysmal subarachnoid haemorrhage. These patients should be managed by a combined team with expertise in microsurgery, endovascular surgery and neurointensive care for optimal management outcome. Early diagnosis and treatment is the key to improve outcome and reduce disability and mortality.
