Intraventricular haemorrhage without subarachnoid haemorrhage due to a ruptured aneurysm

Subarachnoid haemorrhage due to upper cervical trauma.

Seventeen cases are reported in which fatal subarachnoid haemorrhage was associated with injury to the upper cervical region. Most of these cases were alcohol-intoxicated, most had sustained their injuries in an altercation, and death was usually but not invariably rapid. It is proposed that trauma to the upper cervical region can cause subarachnoid haemorrhage, by a mechanism involving trackin...

Subarachnoid Haemorrhage

SAH affects 6-9 people per 100,000 of the population per year and constitutes about 6% of first strokes. An apparent decrease from older published figures is attributed to a higher rate of CT scanning, excluding other haemorrhagic causes. Approximately 85% of patients bleed from intracranial arterial aneurysms, 10% from a non-aneurysmal peri-mesencephalic haemorrhage and 5% from other vascular ...

Subarachnoid haemorrhage.

Subarachnoid haemorrhage accounts for only 5% of strokes, but occurs at a fairly young age. Sudden headache is the cardinal feature, but patients might not report the mode of onset. CT brain scanning is normal in most patients with sudden headache, but to exclude subarachnoid haemorrhage or other serious disorders, a carefully planned lumbar puncture is also needed. Aneurysms are the cause of s...

Corticosteroid therapy of experimental hydrocephalus after intraventricular-subarachnoid haemorrhage.

Symptomatic hydrocephalus after subarachnoid haemorrhage seems to result both from mechanical obstruction of arachnoid villi and basilar cisterns and from an inflammatory cellular reaction in the villi. Subarachnoid haemorrhage was induced in rabbits using whole blood injected through an implanted intraventricular needle. Control rabbits receiving intraventricular methyl prednisolone acetate bu...
