Cerebrospinal Fluid Pressure
Manometric pressure of the CEREBROSPINAL FLUID as measured by lumbar, cerebroventricular, or cisternal puncture. Within the cranial cavity it is called INTRACRANIAL PRESSURE.
Intracranial Pressure
Pressure within the cranial cavity. It is influenced by brain mass, the circulatory system, CSF dynamics, and skull rigidity.
Cerebrospinal Fluid
A watery fluid that is continuously produced in the CHOROID PLEXUS and circulates around the surface of the BRAIN; SPINAL CORD; and in the CEREBRAL VENTRICLES.
Cerebrospinal Fluid Shunts
Tubes inserted to create communication between a cerebral ventricle and the internal jugular vein. Their emplacement permits draining of cerebrospinal fluid for relief of hydrocephalus or other condition leading to fluid accumulation in the ventricles.
Intracranial Hypotension
Reduction of CEREBROSPINAL FLUID pressure characterized clinically by HEADACHE which is maximal in an upright posture and occasionally by an abducens nerve palsy (see ABDUCENS NERVE DISEASES), neck stiffness, hearing loss (see DEAFNESS); NAUSEA; and other symptoms. This condition may be spontaneous or secondary to SPINAL PUNCTURE; NEUROSURGICAL PROCEDURES; DEHYDRATION; UREMIA; trauma (see also CRANIOCEREBRAL TRAUMA); and other processes. Chronic hypotension may be associated with subdural hematomas (see HEMATOMA, SUBDURAL) or hygromas. (From Semin Neurol 1996 Mar;16(1):5-10; Adams et al., Principles of Neurology, 6th ed, pp637-8)
Extracellular Fluid
The fluid of the body that is outside of CELLS. It is the external environment for the cells.
Pressure
A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
Headache
The symptom of PAIN in the cranial region. It may be an isolated benign occurrence or manifestation of a wide variety of HEADACHE DISORDERS.
Intraocular Pressure
The pressure of the fluids in the eye.
Dogs
The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)
Isoflurane
A stable, non-explosive inhalation anesthetic, relatively free from significant side effects.
Hydrostatic Pressure
The pressure due to the weight of fluid.
Blood Pressure
PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.
Cerebrospinal Fluid Proteins
Proteins in the cerebrospinal fluid, normally albumin and globulin present in the ratio of 8 to 1. Increases in protein levels are of diagnostic value in neurological diseases. (Brain and Bannister's Clinical Neurology, 7th ed, p221)
Transducers, Pressure
Transducers that are activated by pressure changes, e.g., blood pressure.
Extracellular Space
Interstitial space between cells, occupied by INTERSTITIAL FLUID as well as amorphous and fibrous substances. For organisms with a CELL WALL, the extracellular space includes everything outside of the CELL MEMBRANE including the PERIPLASM and the cell wall.

Contralateral deafness following unilateral suboccipital brain tumor surgery in a patient with large vestibular aqueduct--case report. (1/123)

A 68-year-old female developed contralateral deafness following extirpation of a left cerebellopontine angle epidermoid cyst. Computed tomography showed that large vestibular aqueduct was present. This unusual complication may have been caused by an abrupt pressure change after cerebrospinal fluid release, which was transmitted through the large vestibular aqueduct and resulted in cochlear damage.  (+info)

Oxygenation of the cat primary visual cortex. (2/123)

Tissue PO2 was measured in the primary visual cortex of anesthetized, artificially ventilated normovolemic cats to examine tissue oxygenation with respect to depth. The method utilized 1) a chamber designed to maintain cerebrospinal fluid pressure and prevent ambient PO2 from influencing the brain, 2) a microelectrode capable of recording electrical activity as well as local PO2, and 3) recordings primarily during electrode withdrawal from the cortex rather than during penetrations. Local peaks in the PO2 profiles were consistent with the presence of numerous vessels. Excluding the superficial 200 microm of the cortex, in which the ambient PO2 may have influenced tissue PO2, there was a slight decrease (4.9 Torr/mm cortex) in PO2 as a function of depth. After all depths and cats were weighted equally, the average PO2 in six cats was 12.8 Torr, with approximately one-half of the values being +info)

The effect of spinal instrumentation on lumbar intradiscal pressure. (3/123)

The purpose of this study was to investigate the effect of spinal instrumentation on the intradiscal pressure (IDP) within the fixed motion segment. In vitro biomechanical testing was performed in six single functional spinal units of fresh calf lumbar spines using a pressure needle transducer. Various loads were applied by a materials testing system device. In addition to intact spine (control), anterior spinal instrumentation (ASI) and pedicle screw fixation (PS) constructs, as well as destabilized spine were tested. Relative to the control, the destabilized spine tended to have an increased IDP; by 15% in axial compression and by 9-36% in flexion-extension. Compared to the control, PS decreased the IDP by 23% in axial loading and 51% in extension loading and increased it by 60% in flexion for each loading. ASI decreased the IDP by 32% in flexion and 1% in extension. Lateral bending produced symmetrical changes of IDP in the control and destabilized spine, but no change in the PS construct. The IDP of the ASI construct was decreased by 77% in ipsilateral bending and increased by 22% in contralateral bending. These results demonstrated that eccentric loading from the spinal instruments increased IDP and significant disc pressure may still exist despite an increase in motion segment stiffness after lumbar stabilization.  (+info)

Spontaneous ventriculostomy: report of three cases revealed by flow-sensitive phase-contrast cine MR imaging. (4/123)

Spontaneous ventriculostomy is a rare condition that occurs with the spontaneous rupture of a ventricle, resulting in a communication between the ventricular system and the subarachnoid space. Three cases of spontaneous ventriculostomy through the floor of the third ventricle that occurred in cases of chronic obstructive hydrocephalus are presented. The communication was identified via flow-sensitive phase-contrast cine MR imaging. Spontaneous ventriculostomy is probably a result of a rupture of the normally thin membrane that forms the floor of the third ventricle and, with long-standing obstructive hydrocephalus, creates an internal drainage pathway that spontaneously compensates for the hydrocephalus.  (+info)

Effects of positive end-expiratory pressure ventilation on cerebral venous pressure with head elevation in dogs. (5/123)

Mechanical ventilation with positive end-expiratory pressure (PEEP) may prevent venous air embolism in the sitting position because cerebral venous pressure (Pcev) could be increased by the PEEP-induced increase in right atrial pressure (Pra). Whereas it is clear that there is a linear transmission of the PEEP-induced increase in Pra to Pcev while the dog is in the prone position, the mechanism of the transmission with the dog in the head-elevated position is unclear. We tested the hypothesis that a Starling resistor-type mechanism exists in the jugular veins when the head is elevated. In one group of dogs, increasing PEEP linearly increased Pcev with the dog in the prone position (head at heart level, slope = 0.851) but did not increase Pcev when the head was elevated. In another group of dogs, an external chest binder was used to produce a larger PEEP-induced increase in Pra. Further increasing Pra increased Pcev only after Pra exceeded a pressure of 19 mmHg (break pressure). This sharp inflection in the upstream (Pcev)-downstream (Pra) relationship suggests that this may be caused by a Starling resistor-type mechanism. We conclude that jugular venous collapse serves as a significant resistance in the transmission of Pra to Pcev in the head-elevated position.  (+info)

Isolated dilation of the trigono-inferior horn--four case reports. (6/123)

Four patients presented with isolated dilation of the trigono-inferior horn associated with either mass lesion at the trigone of the lateral ventricle or with shunt over-drainage. We investigated clinical symptoms, course, and neuroradiological findings of these cases. The pressure of the isolated ventricle was measured or estimated at surgery in all cases. The common symptoms were recent memory disturbance and contralateral homonymous hemianopia. Contralateral hemiparesis was observed occasionally. Rapid deterioration of the isolation caused uncal herniation in one case. Comma-shaped dilation of the inferior horn was observed in all cases. Midline shift was not conspicuous except in one case. Intraventricular pressure at surgery was 18 cmH2O, 35 cmH2O, 3 cmH2O, and within normal range. These cases had very similar clinical symptoms and neuroradiological findings. The pathophysiology of isolation suggested three types of isolation (high-, normal-, and low-pressure isolation), depending on the pressure of the isolated ventricle. The isolation of trigono-inferior horn is an important clinical entity as it may cause uncal herniation in patients with high-pressure lesions.  (+info)

How much work is required to puncture dura with Tuohy needles? (7/123)

The effects of needle bevel orientation and cerebrospinal fluid (CSF) pressure on dural displacement and force required to penetrate cadaveric dura were studied using 40 samples. A constant hydrostatic pressure was applied to the subdural surface, either high or low, simulating the sitting and lateral positions. A 17-gauge Tuohy needle was advanced through the dura with the bevel oriented parallel or perpendicular to dural fibres. Travel distance and peak force at which dural penetration occurred were measured under both pressure conditions. The work required to produce dural penetration was calculated. Greater force and work were required to penetrate dura in the perpendicular orientation (P < 0.05), regardless of the subdural pressure exerted. Dural displacement was similar under both pressure conditions.  (+info)

CSF flow measurement in syringomyelia. (8/123)

BACKGROUND AND PURPOSE: CSF circulation has been reported to represent a major factor in the pathophysiology of syringomyelia. Our purpose was to determine the CSF flow patterns in spinal cord cysts and in the subararachnoid space in patients with syringomyelia associated with Chiari I malformation and to evaluate the modifications of the flow resulting from surgery. METHODS: Eighteen patients with syringomyelia were examined with a 3D Fourier encoding velocity imaging technique. A prospectively gated 2D axial sequence with velocity encoding in the craniocaudal direction in the cervical region was set at a velocity of +/- 10 cm/s. Velocity measurements were performed in the larger portion of the cysts and, at the same cervical level, in the pericystic subarachnoid spaces. All patients underwent a surgical procedure involving dural opening followed by duroplasty. Pre- and postoperative velocity measurements of all patients were taken, with a mean follow-up of 10.2 months. We compared the velocity measurements with the morphology of the cysts and with the clinical data. Spinal subarachnoid spaces of 19 healthy subjects were also studied using the same technique. RESULTS: A pulsatile flow was observed in syrinx cavities and in the pericystic subarachnoid spaces (PCSS). Preoperative maximum systolic cyst velocities were higher than were diastolic velocities. A systolic velocity peak was well defined in all cases, first in the cyst and then in the PCSS. Higher systolic and diastolic cyst velocities are observed in large cysts and in patients with a poor clinical status. After surgery, a decrease in cyst volume (evaluated on the basis of the extension of the cyst and the compression of the PCSS) was observed in 13 patients. In the postoperative course, we noticed a decrease of systolic and diastolic cyst velocities and a parallel increase of systolic PCSS velocities. Diastolic cyst velocities correlated with the preoperative clinical status of the patients and, after surgery, in patients with a satisfactory foraminal enlargement evaluated on the basis of the visibility of the cisterna magna. CONCLUSION: CSF flow measurement constitutes a direct evaluation for the follow-up of patients with syringomyelic cysts. Diastolic and systolic cyst velocities can assist in the evaluation of the efficacy of surgery.  (+info)

The role of cerebrospinal fluid pressure in glaucoma and other ophthalmic diseases: A review | Noninvasive ICPThe role of cerebrospinal fluid pressure in glaucoma and other ophthalmic diseases: A review | Noninvasive ICP
Authors: Fleischman D, Allingham RR.. Glaucoma is one of the most common causes of blindness in the world. Well-known risk factors include age, race, a positive family history and elevated intraocular pressures. A newly proposed risk factor is decreased cerebrospinal fluid pressure (CSFP). This concept is based on the notion that a pressure differential exists across the lamina cribrosa, which separates the intraocular space from the subarachnoid fluid space. In this construct, an increased translaminar pressure difference will occur with a relative increase in elevated intraocular pressure or a reduction in CSFP. This net change in pressure is proposed to act on the tissues within the optic nerve head, potentially contributing to glaucomatous optic neuropathy. Similarly, patients with ocular hypertension who have elevated CSFPs, would enjoy a relatively protective effect from glaucomatous damage. This review will focus on the current literature pertaining to the role of CSFP in glaucoma. ...

Cerebrospinal fluid pressure (CSFp) provides vital information in various neurological abnormalities including hydrocephalus, intracranial hypertension and brain tumors. Currently, CSFp is measured invasively through implanted catheters within the brain (ventricles and parenchyma) which is associated with a risk of infection and morbidity. In humans, the cerebrospinal fluid communicates indirectly with the ocular circulation across the lamina cribrosa via the optic nerve subarachnoid space. It has been shown that a relationship between retinal venous pulsation, intraocular pressure (IOP) and CSFp exists with the amplitude of retinal venous pulsation being associated with the trans-laminar pressure gradient (i.e. IOP-CSFp). In this study we use this characteristic to develop a non-invasive approach to estimate CSFp. 15 subjects were included in this study. Dynamic retinal venous diameter changes and IOP were measured and fitted into our model. Artificial neural networks (ANN) were applied to ...

cerebrospinal fluid pressure | Noninvasive ICPcerebrospinal fluid pressure | Noninvasive ICP
Authors: Silverman CA, Linstrom CJ.. We describe tympanic membrane displacement (TMD) testing for non-invasive estimation of intracranial pressure (ICP). With the TMD test, displacement of the tympanic membrane of the middle ear is recorded during elicitation of the acoustic middle-ear reflex (AR). Increased intracranial/perilymphatic pressure displaces the resting stapes footplate laterally so that TMD during the acoustic reflex is medial. Decreased intracranial/perilymphatic pressure displaces the baseline stapes footplate position medially (inward) so that TMD during the AR is lateral. The TMD typically is bidirectional when intracranial/perilymphatic pressure is normal. Discrepant findings have been reported for the sensitivity of the TMD test to ICP as the regression of TMD on invasive measurement of the ICP reveals substantial intersubject variability and overlap among patient and control groups. Large-sample research on TMD test performance in healthy persons and patients with various ...

Case: A 56 year old man presented with new onset headaches with visual symptoms. Physical examination was normal apart from asymmetrical papilledema and reduced visual acuity 6/9 bilaterally. CSF opening pressure was 26 cm H2O. CTV showed partially recanalised thrombosis in the superior sagittal sinus and the right sigmoid and transverse sinuses which appeared chronic. His headaches initially improved with propranolol but he continued to complain of visual symptoms; repeat CSF opening pressure was 31 cm H2O and repeat CTV was reported as, more occlusive. He was therefore anti-coagulated and treated with acetazolamide.. Six weeks after starting treatment, ophthalmological assessment found worsening visual fields despite reduction in disc swelling on OCT. CSF pressure remained elevated at 30 cm H2O. Repeat CTV and 4D CTA identified a type IIB occipital dural AV fistula around the thrombosed venous sinuses, causing occipital lobe congestion; the likely cause of the visual field defects.. The ...

Background: Many aspects of CSF dynamics are poorly understood due to the difficulties involved in quantification and visualization. In particular, there is debate surrounding the route of CSF drainage. Our aim was to quantify CSF flow, volume, and drainage route dynamics in vivo in young and aged spontaneously hypertensive rats (SHR) using a novel contrast-enhanced computed tomography (CT) method.Methods: ICP was recorded in young (2-5 months) and aged (16 months) SHR. Contrast was administered into the lateral ventricles bilaterally and sequential CT imaging was used to visualize the entire intracranial CSF system and CSF drainage routes. A customized contrast decay software module was used to quantify CSF flow at multiple locations.Results: ICP was significantly higher in aged rats than in young rats (11.52 ± 2.36 mmHg, versus 7.04 ± 2.89 mmHg, p = 0.03). Contrast was observed throughout the entire intracranial CSF system and was seen to enter the spinal canal and cross the cribriform plate ...

Five in vitro models were constructed which were representative of various pathologies of the spinal canal (SC) associated with syringomyelia (SM). The models were subjected to a cough type flow impulse while monitoring the pressure environment in the syrinx and subarachnoid space (SAS) regions of the model. The results indicated that conditions can arise during a cough which would provide pressure forces to encourage cerebrospinal fluid (CSF) movement into the syrinx cavity. The flow obstruction (stenosis) acted as an inflection point for transmural pressure (TP) in which the far region of the syrinx was expanded and the near region was compressed. In the case when a stenosis was present, but no syrinx had formed, the longitudinal pressure gradient and pulse pressures were highest on the SC. However, when a syrinx was present, the pressures were reduced, but still pathological. The primary point of pressure gradients in all of the experiments was the stenosis which caused large pressure ...

While research in animal models of spinal cord injury have provided many promising insights, human studies have failed to produce effective therapies. We propose to investigate the drug Minocycline (a metalloproteinase inhibitor) for the treatment of spinal cord injured patients aiming to limit neurological injury and improve neurological outcome. This drug influences several secondary injury mechanisms implicated in spinal cord injury and has been effective in improving outcome after spinal cord injury in animal models. We also propose to examine the safety and feasibility of spinal cord perfusion pressure augmentation with a protocol of IV fluids and inotrope medications versus standard maintenance of mean arterial pressure in subjects who exhibit a decrease in perfusion pressure to less than 75 mmHg. The purpose of this pilot study is 1) to evaluate the feasibility of a clinical trial protocol for Minocycline in patients with acute spinal cord injury, and 2) to ensure adequate drug dosing and ...

A Novel Rat Model to Study the Role of Intracranial Hypotension in Optic Neuropathy | IOVS | ARVO JournalsA Novel Rat Model to Study the Role of Intracranial Hypotension in Optic Neuropathy | IOVS | ARVO Journals
Purpose: Retrospective studies from our laboratory have identified low cerebrospinal fluid pressure (CSFP) as a risk factor for glaucoma. The low CSFP will presumably be reflected in a proportionally lowered intracranial pressure (ICP). Unfortunately, there are no existing animal models to investigate the role of ICP and the glaucoma phenotype. In the current study, we developed a rat model that can be used to manipulate ICP, and eventually be used to study the role of ICP on optic neuropathy.. Methods: Brown Norway rats (n=3, retired breeders, age ,8 months, weight , 300 g) were surgically implanted with a 20 gauge cannula into the lateral ventricle. The cannula was held in place by dental cement and secured to the skull with 4 screws. An external 3 mm post was connected to PE60 tubing protected by a flexible metal tether. The tether was connected to a swivel mount that enabled movement within the cage. The tubing was attached to a pressure transducer connected to a computer that recorded ICP ...

TY - JOUR. T1 - The effect of renin-angiotensin system blockade on visceral blood flow during and after thoracic aortic cross-clamping. AU - Joob, A. W.. AU - Harman, P. K.. AU - Kaiser, D. L.. AU - Kron, I. L.. PY - 1986. Y1 - 1986. N2 - Surgical procedures necessitating clamping of the thoracic aorta are associated with a high incidence of postoperative renal dysfunction. Plasma renin activity is elevated during and after thoracic aortic occlusion in animals. The pathophysiology of the renal dysfunction may involve the renin-angiotensin system. Blockade of the renin-angiotensin system was studied in a canine model during occlusion of the thoracic aorta. Saralasin, a competitive blocker of angiotensin II, and the converting enzyme inhibitor MK422 were studied. Sixteen animals were separated into three treatment groups: control (five animals), saralasin (five), and MK422 (six). All dogs underwent clamping of the thoracic aorta for 60 minutes. In control animals, plasma renin activity increased ...

Tarlov CystTarlov Cyst
Tarlov cysts are sacs filled with cerebrospinal fluid that most often affect nerve roots in the sacrum, the group of bones at the base of the spine. These cysts (also known as meningeal or perineural cysts) can compress nerve roots, causing lower back pain, sciatica (shock-like or burning pain in the lower back, buttocks, and down one leg to below the knee), urinary incontinence, headaches (due to changes in cerebrospinal fluid pressure), constipation, sexual dysfunction, and some loss of feeling or control of movement in the leg and/or foot. Pressure on the nerves next to the cysts can also cause pain and deterioration of surrounding bone. Tarlov cysts can be diagnosed using magnetic resonance imaging (MRI); however, it is estimated that 70% of the cysts observed by MRI cause no symptoms. Tarlov cysts may become symptomatic following shock, trauma, or exertion that causes the buildup of cerebrospinal fluid.

An accurate and reproducible method for measuring the volume of the cranial CSF spaces was developed in the MRI unit in Glasgow by Dr. B. Condon in 1986. Using this MRI method the total cranial, cortical sulcal, ventricular and posterior fossa CSF volumes could be accurately measured, whereas only ventricular CSF volume could be estimated by previous techniques. The aim of this thesis was firstly to examine the technique critically and to reduce factors that might affect the accuracy or reproducibility of CSF volume measurement; secondly, to determine the normal range of CSF volume; thirdly, to study physiological factors that might influence the cranial CSF volume; and lastly to assess the research and clinical potential of these measurements in conditions where the CSF volumes might be altered. The original technique was modified. The accuracy of the method was improved by using 0.9% sodium chloride as a calibration reference solution, rather than water, as saline was found to produce a signal ...

A Theoretical Model to Allow Prediction of the CSF Pressure From Observations of the Retinal Venous Pulse | IOVS | ARVO JournalsA Theoretical Model to Allow Prediction of the CSF Pressure From Observations of the Retinal Venous Pulse | IOVS | ARVO Journals
For constant IOP (setting A I = 0 mm Hg), the model prediction of the channel constriction in the eye compartment (region I) is illustrated as the solid line in Figure 2a as a function of time over a complete period of ICP oscillation (Fig. 2a, dashed line), with a mean IOP of P I = 18.0 mm Hg and a mean ICP of P III = 0 mm Hg. For these parameter values, the wall of the vessel in compartment I exhibited a small amplitude oscillation of a frequency identical to that of the ICP but a quarter cycle out of phase (Fig. 2a, dashed line). However, when the mean IOP was increased to P I = 18.5 mm Hg, the vessel wall in compartment I exhibited a transient violent oscillation of much higher frequency than that of the ICP pulsation (Fig. 2b), consistent with the onset of RVP in the vein at the optic disc. The critical value of IOP where onset was observed is a function of ICP but also the RBF, Q, the vein diameter d and the vessel tension T. The dependency on each of these parameters is explored in the ...

Optic nerve sheath ultrasound is a noninvasive method for the assessment of the risk of raised ICP. The subarachnoid spaces surrounding the optic nerve communicate with the intracranial cavity and changes in cerebrospinal fluid pressure are transmitted along the optic nerve sheath.20 In the anterior part of the optic nerve and particularly in the retrobulbar segment, the nerve is only surrounded by orbital fat. The retrobulbar optic nerve sheath is therefore distensible and can inflate in case of raised cerebrospinal fluid pressure. Comparing ocular ultrasonography with gold standard measures of ICP (invasive devices), values of ONSD above 5.8 mm have been shown to be associated with a 95% risk of raised ICP (i.e. , more than 20 mmHg).13 Such values were obtained in 19% of our preeclamptic patients, suggesting a substantial incidence of raised ICP in this population. However, we were not able to show any relationship between preeclampsia severity and the magnitude of ONSD enlargement. This can ...

The concentration of extracellular molecules sampled is influenced by recovery-that is, the relation between the true extracellular concentration and the concentration found in the sample collected. Recovery depends on many factors, the most important being membrane length and perfusion rate. Two different membrane lengths and a wide range of perfusion rates have been used in previous studies. Additionally, the concentration of metabolites and amino acids differs between different areas of the brain. As most previous studies have been done in patients with different pathological conditions and with a juxtacortical placement of the microdialysis catheter, there is a lack of comparable normal values for human brain metabolism. The interpretation of our results must therefore be restricted to the patterns in metabolite concentrations and their alterations.. The pattern of baseline values on day 1 of our study-that is, before manipulation of the CSF system-were consistent with disrupted energy ...

Hosokawa, Mio - OU Author List - OKAYAMA UNIVERSITY SCIENTIFIC ACHIEVEMENT REPOSITORY
We report a case of POEMS syndrome in a 20-year-old patient diagnosed after visiting an eye clinic with a chief complaint of reduced visual acuity. A male university student aged 20 years was referred to our department complaining of blurred vision in both eyes that had persisted for 1 month. He also noted headache, nausea, and paresthesia in the lower extremities around the same time. The visual acuity of his right and left eye was 20/40 and 20/20, respectively. Optic disc edema and serous retinal detachment were present. Brain magnetic resonance imaging showed no intracranial abnormalities, while elevated cerebrospinal fluid pressure, reduced nerve conduction velocity in both lower extremities, hepatosplenomegaly, M proteinemia, high blood VEGF levels, osteoblastic and osteolytic changes in the spine, and atypical plasma cells in bone lesions were noted. From the above findings, the patient was diagnosed with POEMS syndrome. He received high-dose dexamethasone, thalidomide, and radiotherapy on ...

Indices of cerebrovascular pressure reactivity (CPR) represent surrogate markers of cerebral autoregulation. Given that intracranial pressure (ICP) wave amplitude-guided management, as compared with static ICP-guided management, improves outcome following aneurysmal subarachnoid hemorrhage (SAH), indices of CPR derived from pressure wave amplitudes should be further explored. This study was undertaken to investigate the value of CPR indices derived from static ICP-arterial blood pressure (ABP) values (pressure reactivity index [PRx]) versus ICP-ABP wave amplitudes (ICP-ABP wave amplitude correlation [IAAC]) in relation to the early clinical state and 12-month outcome in patients with aneurysmal SAH. ...

Intravoxel Incoherent Motion at 7 Tesla to quantify human spinal cord perfusion: Limitations and promises - Aix-Marseille...
Purpose To develop a noninvasive technique to map human spinal cord (SC) perfusion in vivo. More specifically, to implement an intravoxel incoherent motion (IVIM) protocol at ultrahigh field for the human SC and assess parameters estimation errors. Methods Monte‐Carlo simulations were conducted to assess estimation errors of 2 standard IVIM fitting approaches (two‐step versus one‐step fit) over the range of IVIM values reported for the human brain and for typical SC diffusivities. Required signal‐to‐noise ratio (SNR) was inferred for estimation of the parameters product, fIVIMD* (microvascular fraction times pseudo‐diffusion coefficient), within 10% error margins. In‐vivo IVIM imaging of the SC was performed at 7T in 6 volunteers. An image processing pipeline is proposed to generate IVIM maps and register them for an atlas‐based region‐wise analysis. Results Required b = 0 SNRs for 10% error estimation on fIVIMD* with the one‐step fit were 159 and 185 for diffusion

Spinal CSF leaks in SIH, which can be detected by myelography in some cases, cause loss of CSF volume, which some investigators believe results in the changes seen on brain imaging.10,11 Given the known relationship between pressure and volume in a closed system, one would expect that these imaging signs of SIH would also be correlated with low CSF pressure, another common finding in SIH. To the contrary, however, our investigation shows that while the presence of ≥1 brain imaging sign is relatively common in patients with SIH, there is weak correlation between individual brain or myelographic imaging signs and a patients CSF pressure. As a result, discordance between the expected imaging signs and the finding of low CSF pressure is routinely encountered.. This discordance indicates that the imaging findings associated with SIH are not uniformly accompanied by a low-pressure state. Furthermore, it reinforces the need to pursue the diagnosis by using a combination of CSF pressure measurement, ...

CRANIOSACRAL THERAPY. Craniosacral Therapy focuses on the bodys cerebrospinal fluid and fascial membranes that surround the brain and spinal cord and their connection with every structure in the body. Through gentle, non-invasive touch a practitioner releases craniosacral and fascial restrictions to improve the overall functioning of the central nervous system. Craniosacral Therapy is a gentle hands-on technique which detects and re-aligns imbalances in the bony structures, soft tissues and the rhythmical flow of fluids throughout the craniosacral system.. Craniosacral Therapy creates more space for the brain, organs and tissues to function, allowing physical and emotional challenges to be dealt with and resolved more easily. By re-aligning and rebalancing the craniosacral system, the brain and spinal cord are provided with the necessary nutrition from the cerebrospinal fluid (CSF). Craniosacral therapy directly impacts the central nervous system, thus any imbalance in this system could ...
