PURPOSE Visual impairment and intracranial pressure (VIIP) syndrome is a health concern for long-duration spaceflight, and a proposed risk factor is elevation of intracranial pressure (ICP). Our goal was to use finite element modeling to simulate how elevated ICP and interindividual differences affect tissue deformation within the optic nerve head (ONH). METHODS We considered three ICP condit...

Mortality and adverse neurologic sequelae from HIV-associated cryptococcal meningitis (HIV-CM) remains high due to raised intracranial pressure (ICP) complications. Cerebrospinal fluid (CSF) high opening pressure occurs in more than 50% of HIV-CM patients. Repeated lumbar puncture with CSF drainage and external lumbar drainage might be required in the management of these patients. Usually, ther...

OBJECTIVE This study evaluates the value of continuous dynamic monitoring of intracranial pressure (ICP) in patients with hypertensive intracerebral hemorrhage to predict early postoperative complications. PATIENTS AND METHODS Data from 80 patients treated in our hospital from February 2014 to February 2015 were analyzed. The patients all underwent decompressive craniectomies, and their ICP c...

The aim of this open, descriptive and prospective study was to determine if the new monitoring parameter "continuous intracranial compliance (cICC)" decreases with age in patients with traumatic brain injury (TBI). 30 patients with severe and moderate TBI (Glasgow Coma Scale score < or = 10) contributing to a European multicenter study, organized by the Brain-IT group, underwent computerized mo...

BACKGROUND Monitoring of intracranial pressure (ICP) is highly important for detecting abnormal brain conditions such as intracranial hemorrhage, cerebral edema, or brain tumor. Until now, the monitoring of ICP requires an invasive method which has many disadvantages including the risk of infections, hemorrhage, or brain herniation. Therefore, many non-invasive methods have been proposed for es...

Background: Intracranial hypertension (IH) is a secondary clinical condition due to the loss of brain compensatory mechanisms, leading increased intracranial pressure (ICP) and changes in cerebral blood flow, which can result hypoxia, injury, herniation. Brain4care (b4c) device that explores variations compliance allows measurement ICP non-invasive serial way, addition, it predict evolution tre...

The accuracy of estimating intracranial pressure in brain tissue (ICP(BT)) via lumbar space was investigated using preset pressure levels in the interval 0 to 600 mm H(2)O in patients with communicating hydrocephalus. Lumbar space ICP correlated excellently to ICP(BT), demonstrated by a measured mean difference of 10 mm H(2)O (0.75 mm Hg) and a regression coefficient of 0.98. The concurrence su...

OBJECTIVE The purpose of this study is to explore the possibilities of an early warning system by measuring intracranial pressure differences in order to prevent secondary insults to the injured brain. METHODS Fifty-five cases with a Glasgow coma scale (GCS) score 8 or below who presented with intracranial hypertension due to various intracranial pathologies underwent bilateral intraparenchym...

Symptomatic overdrainage of cerebrospinal fluid (CSF) can be seen in shunted hydrocephalus patients and in non-shunted patients with spontaneous intracranial hypotension (SIH). In these patients, intracranial pressure (ICP) monitoring often reveals negative static ICP, while it is less understood how the pulsatile ICP (cardiac induced ICP waves) is affected. This latter aspect is addressed in t...

─We describe a computer model of intracranial pressure (ICP) dynamics that evaluates clinical treatment options for elevated ICP during traumatic brain injury (TBI). The model uses fluid volumes as primary state variables and explicitly models fluid flows as well as the resistance, compliance, and pressure associated with each intraand extracranial compartment (arteries and arterioles, capillar...
