The intracranial pressure was monitored continuously for at least 48 hours in five patients with empty sella syndrome, who did not have clinical benign intracranial hypertension (BIH). It has been suggested that the empty sella syndrome is a result of chronically elevated intracranial pressure in the presence of a congenitally deficient diaphragma sellae. However, whilst the intracranial pressu...

The effect of intravenous mannitol infusion and withdrawal of cerebrospinal fluid on the intracranial pressure and clinical state was studied in 26 patients with raised intracranial pressure after direct surgery for ruptured aneurysm. Each method decreased the mean intracranial pressure by about 60% of the pre-treatment level. The maximal decrease following mannitol occurred after 60-90 minutes...

Intracranial pressure (ICP) measurement is an extremely important part of the neurosurgical armamentarium. Not only is raised ICP the commonest cause of death in neurosurgical patients, it is extremely common in patients suffering from head injury. In this latter group, 40% of patients who are admitted in an unconscious state have raised ICP, and in 50% of those who die, raised ICP is the main ...

PURPOSE To investigate the usefulness of transcranial Doppler ultrasonography in the evaluation of intracranial pressure changes after head injury. METHODS Transcranial Doppler examinations and intracranial pressure measurements using intraparenchymal monitors were performed in 12 cases of closed head injury. Twenty-four sets of data, including the Glasgow Coma Scale, intracranial pressure, t...

Physiology and pathophysiology The management of a patient who has sustained a severe cerebral insult requires an understanding of the volume pressure relationship of the intracranial contents: cerebrospinal fluid (CSF), intravascular blood, and brain tissue. Intracranial pressure (ICP) is the pressure relative to atmospheric pressure within the ventriculo-subarachnoid space. Pressures are give...
