OBJECTIVE: The diagnosis and management of patients with idiopathic intracranial hypertension (IIH) frequently relies on lumbar puncture to ascertain intracranial pressures. However, pressures derived this way may be spurious due to patient body habitus and behavior. We recently incorporated direct continuous intracranial pressure (ICP) monitoring into the work-up for IIH and review our experience and outcomes. METHODS: Through billing records, we identified all patients during a 3-year period who had a diagnosis of idiopathic intracranial hypertension and who underwent ICP monitoring prior to shunt placement or revision...

OBJECTIVES: Small series have suggested that outcomes after abusive head trauma are less favorable than after other injury mechanisms. We sought to determine the impact of abusive head trauma on mortality and identify factors that differentiate children with abusive head trauma from those with traumatic brain injury from other mechanisms. DESIGN: First 200 subjects from the Approaches and Decisions in Acute Pediatric Traumatic Brain Injury Trial-a comparative effectiveness study using an observational, cohort study design...

OBJECTIVE Intravenous nicardipine is commonly used for blood pressure reduction in patients with acute stroke. However, few studies have described its effects on cerebrovascular hemodynamics as measured by transcranial Doppler (TCD) waveform analysis and pulsatility index (PI). In this study, the authors report examples of a consistent but paradoxical finding associated with nicardipine that suggests intracranial vasoconstriction, contrary to what is expected from a vasodilator. METHODS The data presented are from a convenience sample of patients who underwent TCD monitoring before, after, or during nicardipine administration...

Background. The increase of the optic nerve sheath diameter (ONSD) is a reliable, noninvasive sonographic marker of intracranial hypertension. Aim of the study was to demonstrate the efficacy of ONSD evaluation, when monitoring neurocritical patients, to early identify malignant intracranial hypertension in patients with brain death (BD). Methods. Data from ultrasound ONSD evaluation have been retrospectively analyzed in 21 sedated critical patients with neurological diseases who, during their clinical course, developed BD...

Newly published clinical practice guidelines recommend intracranial pressure (ICP) monitoring in critical care for the management of pediatric acute encephalopathy (pAE), but the utility of ICP monitoring for pAE has been poorly studied. We recently performed direct ICP monitoring for two patients. We observed that although the direct ICP monitoring had clinical benefits with less body weight gain and no vasopressor use in both cases, this monitoring technique is still invasive. Future studies should determine the utility of non-invasive ICP monitoring systems in pAE to further improve the quality of intensive-care management...

Dialysis disequilibrium syndrome (DDS) is a serious neurological complication of hemodialysis, and patients with acute brain injury are at increased risk. We report a case of DDS leading to intracranial hypertension in a patient with anoxic brain injury and discuss the subsequent dialysis strategy. A 13-year-old girl was admitted after prolonged resuscitation from cardiac arrest. Computed tomography (CT) revealed an inferior vena cava aneurysm and multiple pulmonary emboli as the likely cause. An intracranial pressure (ICP) monitor was inserted, and, on day 3, continuous renal replacement therapy (CRRT) was initiated due to acute kidney injury, during which the patient developed severe intracranial hypertension...

BACKGROUND: Primary amebic meningoencephalitis is a rare, almost uniformly fatal disease of cerebral invasion by Naegleria fowleri, occurring most commonly after swimming in warm fresh water in summer months. Treatment using the experimental medication miltefosine demonstrated improved survival and favorable neurocognitive outcome in a 2013 North American patient. Little has been described regarding electrographic recordings of such patients, and little is known to compare known pediatric cases of survival...

OBJECTIVE Approximately 475,000 children are treated for traumatic brain injury (TBI) in the US each year; most are classified as mild TBI (Glasgow Coma Scale [GCS] Score 13-15). Patients with positive findings on head CT, defined as either intracranial hemorrhage or skull fracture, regardless of severity, are often transferred to tertiary care centers for intensive care unit (ICU) monitoring. This practice creates a significant burden on the health care system. The purpose of this investigation was to derive a clinical decision rule (CDR) to determine which children can safely avoid ICU care...

BACKGROUND: Intraventricular haemorrhage (IVH) causes blockage of ventricular conduits leading to hydrocephalus, increased intracranial pressure (ICP), and a reduced level of consciousness. The current standard management of IVH is insertion of an external ventricular drainage (EVD) catheter. However, this procedure addresses only the problems of acute hydrocephalus and raised ICP. Endoscopic washout allows for a more complete removal of the intraventricular clot. This study compared these two types of treatment in terms of shunt dependency and relevant clinical outcomes...

OBJECTIVE: While a significant amount of experience has accumulated for awake procedures for brain tumor, epilepsy and carotid surgery, its utility for intracranial neurovascular indications remains largely undefined. Awake surgery, for select neurovascular cases, offers the advantage of precise brain mapping and robust neurological monitoring during surgery for lesions in eloquent areas, avoidance of potential hemodynamic instability, and possible faster recovery. Additionally, it opens the window for perilesional epileptogenic tissue resection with potentially less risk for iatrogenic injury...

Background Primary cough headache (PCH) is precipitated by coughing or the Valsalva manoeuver (VM), and its underlying pathophysiology remains unclear. Case report We report a case of recurrent cough headaches precipitated by VM with transient increase of intracranial pressure (ICP) diagnosed by measuring left sigmoid sinus pressure. Bilateral internal jugular vein valve incompetence (IJVVI) was also diagnosed by Doppler ultrasonography during a VM. Indomethacin was administered for over four months, and the headache had completely disappeared at the four-month follow-up...

Symptomatic intracranial hemorrhage (sICH) is a major complication after intravenous thrombolysis leading to severe disability and death. The incidence was higher in Asian than in westernized countries. Prognostic factors across ethnicities are presumably different. Studies in Asian populations are limited. Clinical data from January 2008 to September 2016 in one provincial and four regional hospitals in the northern part of Thailand were retrospectively reviewed. Patients were those with acute ischemic stroke, to whom recombinant tissue plasminogen activator (rt-PA) had been prescribed...

Mannitol and hypertonic saline (HS) are most commonly used hyperosmotic agents for intraoperative brain relaxation. We compared the changes in ICP and systemic hemodynamics after infusion of equiosmolar solutions of both agents in patients undergoing craniotomy for supratentorial tumors. Forty enrolled adults underwent a standard anesthetic induction. Apart from routine monitoring parameters, subdural ICP with Codmann catheter and cardiac indices by Vigileo monitor, were recorded. The patients were randomized to receive equiosmolar solutions of either 20% mannitol (5ml/kg) or 3% HS (5...

Neuromonitoring can be used to observe intracranial pathological conditions in neurointensive care, but use of intracranial pressure (ICP) monitoring is low in Japan. In this study, we retrospectively investigated the effects of ICP monitoring in treatment of severe traumatic brain injury (TBI) using data from the Japan Neurotrauma Data Bank (JNTDB). The study was conducted in 1,091 subjects enrolled in the JNTDB (Project 2009) from July 2009 to June 2011. The subjects were divided into those treated with and without ICP monitoring in intensive care for severe TBI...

The brain and heart are two vital systems in health and disease, increasingly recognised as a complex, interdependent network with constant information flow in both directions. After severe traumatic brain injury (TBI), the causal, directed interactions between the brain, heart and autonomic nervous system have not been well established. Novel methods are needed to probe unmeasured, potentially prognostic information in complex biological networks that are not revealed via traditional means. In this study, we examined potential bi-directional causality between intracranial pressure (ICP), mean arterial pressure (MAP) and heart rate (HR) and its relationship to mortality in a 24-hour period early after TBI...

BACKGROUND: Brain death (BD)-related lipid peroxidation, measured as serum malondialdehyde (MDA) levels, correlates with delayed graft function in renal transplant recipients. How BD affects lipid peroxidation is not known. The extent of BD-induced organ damage is influenced by the speed at which intracranial pressure increases. To determine possible underlying causes of lipid peroxidation, we investigated the renal redox balance by assessing oxidative and antioxidative processes in kidneys of brain-dead rats after fast and slow BD induction...

BACKGROUND: Familial cases of idiopathic intracranial hypertension (IIH) are exceedingly rare and its occurrence has not been reported before in monozygotic twins. CASE DESCRIPTION: We describe the cases of monozygotic female twins who developed IIH at age 25 and at age 28, respectively. Continuous intracranial pressure monitoring confirmed elevated intracranial pressure (ICP) as measured initially by lumbar puncture. In both cases, successful treatment with resolution of papilledema and symptoms relief was achieved after ventriculoperitoneal shunting...

Possible traumatic brain injury victims would greatly benefit from a handheld, noninvasive intracranial pressure (ICP) monitoring tool, which a medic could operate in a remote area. Such a device would also benefit the transport of injured soldiers during en route medical care and critical care air transport. This study demonstrates the use of noninvasive blood flow measurements in the eye by ultrasound as a proxy for ICP. ICP was artificially raised in a porcine model and resultant blood flow change in the ophthalmic artery was measured...
