Abstract

Between 1926-36 Norman Dott managed 39 patients with suspected intracranial haemorrhage. During this period he established important principles of diagnosis and developed new methods for the medical and surgical treatment of aneurysmal subarachnoid haemorrhage. Dott performed the first intracranial operation to treat an aneurysm and the first angiogram to demonstrate an intracranial aneurysm. This article reviews Dott's early experiences of aneurysmal subarachnoid haemorrhage.
