Cerebral Ventriculography: Radiography of the ventricular system of the brain after injection of air or other contrast medium directly into the cerebral ventricles. It is used also for x-ray computed tomography of the cerebral ventricles.Radionuclide Ventriculography: Imaging of a ventricle of the heart after the injection of a radioactive contrast medium. The technique is less invasive than cardiac catheterization and is used to assess ventricular function.Ventriculography, First-Pass: Radionuclide ventriculography where a bolus of radionuclide is injected and data are recorded from one pass through the heart ventricle. Left and right ventricular function can be analyzed independently during this technique. First-pass ventriculography is preferred over GATED BLOOD-POOL IMAGING for assessing right ventricular function.Gated Blood-Pool Imaging: Radionuclide ventriculography where scintigraphic data is acquired during repeated cardiac cycles at specific times in the cycle, using an electrocardiographic synchronizer or gating device. Analysis of right ventricular function is difficult with this technique; that is best evaluated by first-pass ventriculography (VENTRICULOGRAPHY, FIRST-PASS).Cerebral Arteries: The arterial blood vessels supplying the CEREBRUM.Stroke Volume: The amount of BLOOD pumped out of the HEART per beat, not to be confused with cardiac output (volume/time). It is calculated as the difference between the end-diastolic volume and the end-systolic volume.Angiocardiography: Radiography of the heart and great vessels after injection of a contrast medium.Heart Ventricles: The lower right and left chambers of the heart. The right ventricle pumps venous BLOOD into the LUNGS and the left ventricle pumps oxygenated blood into the systemic arterial circulation.Cineangiography: Motion pictures of the passage of contrast medium through blood vessels.Cerebral Infarction: The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).Heart Aneurysm: A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.Sodium Pertechnetate Tc 99m: A gamma-emitting radionuclide imaging agent used for the diagnosis of diseases in many tissues, particularly in the gastrointestinal system, cardiovascular and cerebral circulation, brain, thyroid, and joints.Ventricular Function, Left: The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.Cerebral Palsy: A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)Radionuclide Angiography: The measurement of visualization by radiation of any organ after a radionuclide has been injected into its blood supply. It is used to diagnose heart, liver, lung, and other diseases and to measure the function of those organs, except renography, for which RADIOISOTOPE RENOGRAPHY is available.Cerebrovascular Circulation: The circulation of blood through the BLOOD VESSELS of the BRAIN.Takotsubo Cardiomyopathy: A transient left ventricular apical dysfunction or ballooning accompanied by electrocardiographic (ECG) T wave inversions. This abnormality is associated with high levels of CATECHOLAMINES, either administered or endogenously secreted from a tumor or during extreme stress.Ventricular Dysfunction, Left: A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.Middle Cerebral Artery: The largest of the cerebral arteries. It trifurcates into temporal, frontal, and parietal branches supplying blood to most of the parenchyma of these lobes in the CEREBRAL CORTEX. These are the areas involved in motor, sensory, and speech activities.Technetium: The first artificially produced element and a radioactive fission product of URANIUM. Technetium has the atomic symbol Tc, atomic number 43, and atomic weight 98.91. All technetium isotopes are radioactive. Technetium 99m (m=metastable) which is the decay product of Molybdenum 99, has a half-life of about 6 hours and is used diagnostically as a radioactive imaging agent. Technetium 99 which is a decay product of technetium 99m, has a half-life of 210,000 years.Heart: The hollow, muscular organ that maintains the circulation of the blood.Iothalamate Meglumine: A radiopaque medium used for urography, angiography, venography, and myelography. It is highly viscous and binds to plasma proteins.Myocardial Infarction: NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).Electrocardiography: Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.Diatrizoate: A commonly used x-ray contrast medium. As DIATRIZOATE MEGLUMINE and as Diatrizoate sodium, it is used for gastrointestinal studies, angiography, and urography.Prenalterol: A partial adrenergic agonist with functional beta 1-receptor specificity and inotropic effect. It is effective in the treatment of acute CARDIAC FAILURE, postmyocardial infarction low-output syndrome, SHOCK, and reducing ORTHOSTATIC HYPOTENSION in the SHY-RAGER SYNDROME.Echocardiography: Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.Technetium Tc 99m Pyrophosphate: A radionuclide imaging agent used primarily in scintigraphy or tomography of the heart to evaluate the extent of the necrotic myocardial process. It has also been used in noninvasive tests for the distribution of organ involvement in different types of amyloidosis and for the evaluation of muscle necrosis in the extremities.Thallium: A heavy, bluish white metal, atomic number 81, atomic weight [204.382; 204.385], symbol Tl.Iopamidol: A non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiological procedures.Cerebral Angiography: Radiography of the vascular system of the brain after injection of a contrast medium.Infarction, Middle Cerebral Artery: NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.Cardiac Volume: The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.Iothalamic Acid: A contrast medium in diagnostic radiology with properties similar to those of diatrizoic acid. It is used primarily as its sodium and meglumine (IOTHALAMATE MEGLUMINE) salts.Malaria, Cerebral: A condition characterized by somnolence or coma in the presence of an acute infection with PLASMODIUM FALCIPARUM (and rarely other Plasmodium species). Initial clinical manifestations include HEADACHES; SEIZURES; and alterations of mentation followed by a rapid progression to COMA. Pathologic features include cerebral capillaries filled with parasitized erythrocytes and multiple small foci of cortical and subcortical necrosis. (From Adams et al., Principles of Neurology, 6th ed, p136)Coronary Disease: An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Tomography, Emission-Computed, Single-Photon: A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.Cardiac Catheterization: Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures.Coronary Angiography: Radiography of the vascular system of the heart muscle after injection of a contrast medium.Cerebral Veins: Veins draining the cerebrum.Dictionaries, MedicalDictionaries as Topic: Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.Dictionaries, ChemicalArchivesBiological Science Disciplines: All of the divisions of the natural sciences dealing with the various aspects of the phenomena of life and vital processes.

Large empty sella with an intrasellar herniation of an elongated third ventricle. Case report. (1/112)

A 73-year-old female presented with a large empty sella with herniation of an elongated third ventricle concomitant with herniation of the surrounding subarachnoid space into the sella, manifesting as visual impairment and amenorrhea without galactorrhea. Magnetic resonance imaging and computed tomography cisternography clearly showed the large empty sella, without evidence of either hydrocephalus or benign intracranial hypertension, which is extremely rare.  (+info)

Midline cerebellar cystic schwannoma : a case report. (2/112)

An extremely unusual case of a cystic schwannoma in the region of the inferior vermis and posterior to the fourth ventricle in a fifteen year old boy is reported. The cystic tumour caused partial obstruction to the outflow of cerebrospinal fluid from fourth ventricle and resulted in development of supratentorial hydrocephalus. On investigations, the schwannoma simulated a Dandy-Walker cyst. The boy presented with symptoms of increased intracranial pressure. On surgery, the lesion was not arising from any cranial nerve, nor was it attached to brain parenchyma, blood vessel or to the dura. The possible histogenesis of the cystic schwannoma in a rare location is discussed.  (+info)

Initial loss of consciousness and risk of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage. (3/112)

BACKGROUND AND PURPOSE: Delayed cerebral ischemia (DCI) is a major cause of death and disability in patients with aneurysmal subarachnoid hemorrhage. We studied the prognostic value for DCI of 2 factors: the duration of unconsciousness after the hemorrhage and the presence of risk factors for atherosclerosis. METHODS: In 125 consecutive patients admitted within 4 days after hemorrhage, we assessed the presence and duration of unconsciousness after the hemorrhage, the neurological condition on admission, the amount of subarachnoid blood, the size of the ventricles, and a history of smoking, hypertension, stroke, or myocardial infarction. The relationship between these variables and the development of DCI was analyzed by means of the Cox proportional hazards model. RESULTS: The univariate hazard ratio (HR) for the development of DCI in patients who had lost consciousness for >1 hour was 6.0 (95% CI 3.0 to 12.0) compared with patients who had no loss or a <1-hour loss of consciousness. The presence of any risk factor for atherosclerosis yielded an HR of 1.4 (95% CI 0.6 to 3.5). The HR for unconsciousness remained essentially the same after adjustment for other risk factors for DCI. The HR for a poor World Federation of Neurological Surgeons score (grade IV or V) on admission was 2.9 (95% CI 1.5 to 5. 5); that for a large amount of subarachnoid blood on CT was 3.4 (95% CI 1.6 to 7.3). CONCLUSIONS: The duration of unconsciousness after subarachnoid hemorrhage is a strong predictor for the occurrence of DCI. This observation may contribute to a better understanding of the pathogenesis of DCI and increased attention for patients at risk.  (+info)

Prediction of effectiveness of shunting in patients with normal pressure hydrocephalus by cerebral blood flow measurement and computed tomography cisternography. (4/112)

Measurement of cerebral blood flow (CBF) and computed tomography (CT) cisternography were performed in 37 patients with a tentative diagnosis of normal pressure hydrocephalus (NPH) to predict their surgical outcome. The mean CBF of the whole brain was measured quantitatively by single photon emission computed tomography with technetium-99m-hexamethylpropylene amine oxime before surgery. The results of CT cisternography were classified into four patterns: type I, no ventricular stasis at 24 hours; type II, no ventricular stasis with delayed clearance of cerebral blush; type III, persistent ventricular stasis with prominent cerebral blush; type IV, persistent ventricular stasis with diminished cerebral blush and/or asymmetrical filling of the sylvian fissures. The mean CBF was significantly lower than that of age-matched controls (p < 0.005). Patients with a favorable outcome had a significantly higher mean CBF than patients with an unfavorable outcome (p < 0.005). Patients with the type I pattern did not respond to shunting. Some patients with type II and III patterns responded to shunting but improvement was unsatisfactory. Patients with type IV pattern responded well to shunting, and those with a mean CBF of 35 ml/100 g/min or over achieved a favorable outcome. The combination of CBF measurement and CT cisternography can improve the prediction of surgical outcome in patients with suspected NPH.  (+info)

Treatment of intraventricular hemorrhage with urokinase : effects on 30-Day survival. (5/112)

BACKGROUND AND PURPOSE: Intraventricular hemorrhage (IVH) remains associated with high morbidity and mortality. Therapy with external ventricular drainage alone has not modified outcome in these patients. METHODS: Twelve pilot IVH patients who required external ventricular drainage were prospectively treated with intraventricular urokinase followed by the randomized, double-blinded allocation of 8 patients to either treatment or placebo. Observed 30-day mortality was compared with predicted 30-day mortality obtained by use of a previously validated method. RESULTS: Twenty patients were enrolled; admission Glasgow Coma Scale score in 11 patients was +info)

The adult radiographic shuntogram. (6/112)

We describe the adult radiographic shuntogram, a simple method to evaluate the function and patency of a ventriculoperitoneal or ventriculoatrial shunt. The procedure involves placing contrast material into the valve of a shunt system and following the flow for appropriate clearing of contrast agent from the shunt tubing. Twenty-three studies were obtained in 15 patients in whom shunt malfunction was suspected. The method can be used to establish valve malfunction, ventricular or distal catheter obstruction, and peritoneal encystment.  (+info)

Radiological abnormalities in temporal lobe epilepsy with clinicopathological correlations. (7/112)

In 73 patients with drug-resistant temporal lobe epilepsy submitted to an unilateral anterior temporal lobectomy the radiographs were studied to see if there were any correlation with the pathology subsequently found and with the outcome of the operation. A small middle cranial fossa, focal calcification, and temporal horn displacement are often better indices of the underlying pathology than temporal horn dilatation alone. In a small number of cases, however, radiological changes were seen on the side opposite to an unilateral EEG focus, thus suggesting bilateral disease.  (+info)

Effect of intracranial pressure of meglumine iothalamate ventriculography. (8/112)

Intraventricular pressure was studied in 12 patients undergoing ventriculography with a water soluble positive contrast medium. Isovolumetric instillation of meglumine iothalamate into the lateral ventricles and the anterior part of the third ventricle caused only a small increase in ventricular fluid pressure (1.3 +/- 0.3 mmHg), but the pressure increased markedly (46.3 +/- 3.7 mmHg; P less than 0.001) when the contrast medium entered the posterior end of the third ventricle, aqueduct of Sylvius,, and fourth ventricle. This sharp increase in intracranial pressure could not be attributed solely to the postural changes or to alterations in arterial blood pressure. Possible mechanisms are discussed.  (+info)

Pneumoencephalography makes use of plain X-ray images. Unfortunately, these are very poor at resolving soft tissues, such as the brain. Moreover, all the structures captured in the image are superimposed on top of each other, which makes it difficult to pick out individual items of interest (unlike modern scanners which are able to produce fine virtual slices of the body, including of soft tissues). Therefore, pneumoencephalography did not usually image abnormalities directly, rather their secondary effects. The overall structure of the brain contains crevices and cavities which are filled by the CSF. Unfortunately, both the brain and the CSF produce similar signals on an X-ray image. However, draining the CSF allows for greater contrast between the brain matter and the (now drained) crevices in and around it, which then show up as dark shadows on the X-ray image. The aim of pneumoencephalography is to outline these shadow-forming air-filled structures so that their shape and anatomical location ...

Concentrations of homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) were significantly higher in CSF obtained after injection of air during pneumoencephalography (PEG) than in lumbar CSF, as drawn before the injection. There was a high correlation between levels in the `mixed and lumbar samples of CSF in the case of each of the two acids. The concentration of lumbar HVA, but not that of 5-HIAA, was negatively correlated with CSF pressure. 5-HIAA levels were low in both samples of CSF in a group of epileptics, by comparison with controls. In two patients with Kufs disease and in one with Niemann-Pick disease, the concentration of HVA was very low in the lumbar sample. The application of a standardized PEG technique in the study of monoamine metabolism in man is suggested.. ...

Monitoring is probably the most important aspect of care of the patient with suspected OSA. Most recommend continuous pulse oximetry (rather than periodic assessment of O2 saturation) but our previous columns have highlighted the problems associated with just using pulse oximetry and the false sense of security that one may develop. Very important in that light is the work of Lynn and Curry (Lynn 2011) who describe 3 patterns of unexpected in-hospital deaths and demonstrate the problems with threshold-based alarms (almost all currently used alarm systems use threshold-based principles) in detecting early deterioration. Indeed, they posit that threshold-based alarms themselves often cause us to miss signs of early deterioration. The second pattern of deterioration they note is the classic CO2 narcosis but they note many of these cases are complicated by the third pattern typical of sleep apnea.

The first brain image of person with psychosis was completed as far back as 1935 using a technique called pneumoencephalography1 (a painful and now obsolete procedure where cerebrospinal fluid is drained from around the brain and replaced with air to allow the structure of the brain to show up more clearly on an X-ray picture).. Pneumoencephalogram of person with psychosis, 1935Modern brain imaging studies, investigating both changes in brain structure and changes in brain function of people undergoing psychotic episodes have shown mixed results.. A 2003 study investigating structural changes in the brains of people with psychosis showed there was significant grey matter reduction in the cortex of people before and after they became psychotic2. Findings such as these have led to debate about whether psychosis is itself neurotoxic and whether potentially damaging changes to the brain are related to the length of psychotic episode. Recent research has suggested that this is not the case3 although ...

A computational fluid dynamics (CFD) model of the cerebrospinal fluid system was constructed based on a simplified geometry of the brain ventricles and their connecting pathways. The flow is driven by a prescribed sinusoidal motion of the third ventricle lateral walls, with all other boundaries being rigid. The pressure propagation between the third and lateral ventricles was examined and compared to data obtained from a similar geometry with a stenosed aqueduct. It could be shown that the pressure amplitude in the lateral ventricles increases in the presence of aqueduct stenosis. No difference in phase shift between the motion of the third ventricle walls and the pressure in the lateral ventricles because of the aqueduct stenosis could be observed. It is deduced that CFD can be used to analyze the pressure propagation and its phase shift relative to the ventricle wall motion. It is further deduced that only models that take into account the coupling between ventricles, which feature a ...

Background: The abdominal pannus is a well known medical condition of a large overhanging apron of skin and fat that extends well beyond the waistline. Technically the proper term is a panniculus but it is far more commonly referred to as a pannus. What defines a pannus is how large the actual overhang is.. There are five degrees of an abdominal pannus from a grade 1 that rests on the mons pubis to a grade 5 that hangs down to the knees. While no abdominal pannus is pleasant for the patient the grade 5 pannus is the most disabling. It not only obstructs the urinary stream and causes associated hygiene issues but its sheer weight makes mobility difficult. It causes tremendous strain on the back and knees and leads to early deterioration of both.. An abdominal panniculectomy procedure should not be confused with a more traditional tummy tuck. The scope of the problem being treated would indicate such but how the operation is performed and under what circumstance is also vastly different. This is ...

BACKGROUND AND PURPOSE: Complex CSF diseases may be underdiagnosed or poorly understood on conventional CT or MR imaging. Although intrathecal CT cisternography with water-soluble iodinated contrast medium has been used, very few studies have dealt with the intrathecal use of gadopentate dimeglumine (Gd-DTPA), though it appears superior to CT. We report our experience with the intrathecal use of Gd-DTPA for MR cisternography and ventriculography in pediatric patients referred for study and treatment of complex CSF-related diseases.. MATERIALS AND METHODS: Ten patients (range, 1 month-16 years of age) were selected after we obtained specific informed consent. Intrathecal gadolinium injection was performed via transfontanelle ventriculostomy, ventriculoperitoneal shunt reservoir, or lumbar puncture. Cases included spontaneous CSF leaks (n = 1), complex traumatic frontoethmoidal fractures with suspected CSF leak (n = 2), multiloculated congenital or acquired hydrocephalus (n = 3), intraventricular ...

The first brain image of an individual with psychosis was completed as far back as 1935 using a technique called pneumoencephalography[81] (a painful and now obsolete procedure where cerebrospinal fluid is drained from around the brain and replaced with air to allow the structure of the brain to show up more clearly on an X-ray picture).. The purpose of the brain is to collect information from the body (pain, hunger, etc.), and from the outside world, interpret it to a coherent world view, and produce a meaningful response. The information from the senses enter the brain in the primary sensory areas. They process the information and send it to the secondary areas where the information is interpreted. Spontaneous activity in the primary sensory areas may produce hallucinations, which the secondary areas misinterpret as information from the real world.. For example, a PET or fMRI scan of a person who claims they hear voices may show activation in the primary auditory cortex, or parts of the brain ...
Anterior choroidal artery territory infarcts. Study of presumed mechanisms. | StrokeAnterior choroidal artery territory infarcts. Study of presumed mechanisms. | Stroke
A previous study suggested that occlusive diseases of small penetrating arteries account for most anterior choroidal artery (AChA) territory infarcts, but half of the patients did not have an echocardiogram. Cases of AChA territory infarcts associated with internal carotid artery stenosis or atrial fibrillation suggest that this hypothesis may be wrong. The aim of this study was to determine the mechanism of 16 nonselected consecutive AChA territory infarcts.. The study population consisted of 8 men and 8 women aged 17 to 89 years. They underwent a computed tomographic scan at the acute stage, Doppler ultrasonography and B-mode echotomography of the cervical arteries, bidimensional transthoracic echocardiography, and cerebral magnetic resonance imaging, replaced by a second computed tomographic scan in 3 patients. Ten patients underwent cerebral angiography. We defined the presumed cause of stroke according to the criteria used in the trial of Org 10172 in acute stroke treatment.. The presumed ...

Robert Edwards, a progenitor of IVF, is "flamboyant"; so, a page later, is the Russian geneticist and embryologist Yury Verlinsky. Kolatas attempts to be colorful can drain her prose of authentic color.. The subtitle of the book is "A Story of Hope, a Familys Genetic Destiny, and the Science That Rescued Them." Kolata tends to take an upbeat, even celebratory tone, but Amanda is looking at an early deterioration and horrific death, which doesnt exactly constitute a story of hope or a rescue by science. And what of Holly and her children, who may well be marching toward a similar agony? Kolata writes that "science presented the Baxley family members with a responsibility theyd never asked for or anticipated-but that each took on in their own daring ...

N2 - The ventriculo-peritoneal shunt is a well established method in the treatment of primary and secondary hydrocephalus. Seventy ventriculo-peritoneal shunt operations were performed on fifty patients encountered at Tri-Service General Hospital during the last 7 years (1976-1982). The underlying causes of hydrocephalus were: brain tumor (25 cases), congenital hydrocephalus (16 cases), post-traumatic hydrocephalus (6 cases) and normal pressure hydrocephalus (3 cases). Twelve of the 50 patients (24%) developed post-operative complications. The complications in this series were: wound infection (5 cases), obstruction of the ventricular catheter (4 cases), disconnection of the reservoir connector (2 cases) and shortening of the peritoneal catheter (1 case). Among these 12 cases, 8 underwent two or more revisions of the shunt. The remaining 4 cases with ...
Final Diagnosis -- Case 797Final Diagnosis -- Case 797
FINAL DIAGNOSIS. Chordoid glioma of the third ventricle WHO 2007 grade II. DISCUSSION. Chordoid glioma is a rare tumor of the third ventricle, firstly proposed as a distinct entity by Brat et al in 1998 (1). To our knowledge (December, 2011), 74 cases (including our case) have been reported. The tumor predominantly occurs in adult women with a female to male ratio of 1.6 to 1 and the mean age at presentation at 45.25 years of age. Most patients have headache, visual symptoms, and memory disturbances. Other symptoms are lethargy, somnolence, endocrine disturbance such as hypothyroidism and diabetes insipidus, and symptoms caused by space occupying lesion and obstructive hydrocephalus are also observed in some patients. Chordoid glioma mainly locates at the third ventricle or nearby structures, hence the name "Chordoid glioma of the third ventricle". Unusual locations without third ventricular association that have been reported are parieto-temporal region (3) and thalamic pulvinar area (5). The ...

White cerebellum sign a reversal of the normal gray/white matter densities and a relatively increased density of the thalami, brainstem and cerebellum; it is also known as dense cerebellum sign or reversal sign. On Computed Tomography, it is seen as hypodensity of the supratentorial brain with reverse increased attenuation of the cerebellum. This ominous sign is a poor prognostic indicator for patients with brain injury. We document a rare case of white cerebellum sign occurring in an eight year old girl who presented to the emergency department with signs of raised intracranial pressure following Ventriculo-peritoneal shunt revision. Our patient improved significantly after resuscitation with mannitol, she was discharged from hospital with an improved Glasgow Coma Score. Our case presents a new opportunity for management of patients with white cerebellar sign. Mannitol is an antioxidant that decrease H|sub|2|/sub|O|sub|2|/sub| by upregulating catalases. It is postulated to have played a role in the
Functional antagonism of alpha-subunits of Kv channel in developing brain ventricular system | DevelopmentFunctional antagonism of alpha-subunits of Kv channel in developing brain ventricular system | Development
The brain ventricular system is essential for neurogenesis and brain homeostasis. Its neuroepithelial lining effects these functions, but the underlying molecular pathways remain to be understood. We found that the K channels expressed in neuroepithelial cells determine formation of the ventricular system. The phenotype of a novel zebrafish mutant characterized by denudation of neuroepithelial lining of the ventricular system and hydrocephalus is mechanistically linked to Kcng4b, the homologue of the "silent" voltage-gated K channel alpha-subunit Kv6.4. We demonstrated that Kcng4b modulates proliferation of cells lining the ventricular system and maintains their integrity. The gain of Kcng4b function reduces brain ventricles. Electrophysiological studies supported an idea that Kcng4b mediates its effects via an antagonistic interaction with Kcnb1, the homologue of the electrically active delayed rectifier K channel subunit Kv2.1. The mutation of kcnb1 reduces the size of ventricular system and ...
JCI - Lipocalin 2 is essential for chronic kidney disease progression in mice and humansJCI - Lipocalin 2 is essential for chronic kidney disease progression in mice and humans
Mechanisms of progression of chronic kidney disease (CKD), a major health care burden, are poorly understood. EGFR stimulates CKD progression, but the molecular networks that mediate its biological effects remain unknown. We recently showed that the severity of renal lesions after nephron reduction varied substantially among mouse strains and required activation of EGFR. Here, we utilized two mouse strains that react differently to nephron reduction - FVB/N mice, which develop severe renal lesions, and B6D2F1 mice, which are resistant to early deterioration - coupled with genome-wide expression to elucidate the molecular nature of CKD progression. Our results showed that lipocalin 2 (Lcn2, also known as neutrophil gelatinase-associated lipocalin [NGAL]), the most highly upregulated gene in the FVB/N strain, was not simply a marker of renal lesions, but an active player in disease progression. In fact, the severity of renal lesions was dramatically reduced in Lcn2-/- mice. We discovered that Lcn2 ...

In our prospective study cohort, membranous obstruction was demonstrated in 92 (68.6%) of 134 cases of hydrocephalus with the use of 3D-CISS at 3T. Intraventricular membranous obstruction is the most common pathologic finding to cause noncommunicating hydrocephalus (85/114 total noncommunicating cases). However, except in the cerebral aqueduct region, conventional images are insensitive in detection of obstructive membranes in the CSF pathway. In this study, they were only demonstrated in 57 (36.3%) of 157 obstruction sites with the use of conventional imaging. In choosing the most appropriate treatment technique and to assess the prognosis in hydrocephalus, the classification of hydrocephalus and demonstration of obstruction, if it exists, are of significant importance.20,33 The terminology and the classification of hydrocephalus are still a matter of debate and are not the aims of our study. However, it is obvious that we need accurate neuroimaging techniques to demonstrate CSF pathways ...

During the last four years we have employed a ventriculo-peritoneal shunt with valve in 110 patients, including 79 hydrocephalic children. The results have shown that physically both the valve shunts draining into the peritoneum or into the blood stream work similarly. In both instances reoperations have not been frequent, as it was the case when no valves were used in the peritoneal shunts. On the other hand, by using ventriculo-peritoneal shunts not only pulmonary microembolism is prevented but also infections involving the draining system are less severe and more easily controlled than those occurring in the ventriculo-atrial shunts.. ...

With the advent of the aging society, dementia becomes the focus of common people. As for the neurodegeneration dementia, no disease modifying treatments have been discovered. Idiopathic normal pressure hydrocephalus (iNPH) is considered as one of reversible dementia, which can be hint by the surgery. In addition, dementia of iNPH is the typical subcortical dementia. Therefore exploring the pathogenic mechanism is conducive to the early diagnosis and treatment. This research is to monitor the changing of iNPHGS, cognitive function, walking ability as well as brain construction imaging and neural network before and after ventriculo-peritoneal shunting in order to demonstrate the pathogenesis of triads. In the process, the supplementary test, for instance, CSF tap test, will be validated the predictive value ...

Soon after Yaz was approved in 2006, it quickly become one of the most popular birth control pills of all time. The success rapidly faded after researchers found that drospirenone, the progestin in Yaz, was associated with up to a three-fold increased risk of blood clots compared to other progestins.. The problem with blood clots is that they can potentially travel to the brain and cause a stroke. In rare cases, blood clots in the brain can cause secondary intracranial hypertension. Similar to BIH, this condition causes high pressure inside the skull due to elevated levels of cerebrospinal fluid. Both conditions cause the same physical symptoms and can become chronic. ...

Cerebrospinal fluid dynamics in non-acute post-traumatic ventriculomegaly | Fluids and Barriers of the CNS | Full TextCerebrospinal fluid dynamics in non-acute post-traumatic ventriculomegaly | Fluids and Barriers of the CNS | Full Text
Post-traumatic hydrocephalus (PTH) is potentially under-diagnosed and under-treated, generating the need for a more efficient diagnostic tool. We aim to report CSF dynamics of patients with post-traumatic ventriculomegaly. We retrospectively analysed post-traumatic brain injury (TBI) patients with ventriculomegaly who had undergone a CSF infusion test. We calculated the resistance to CSF outflow (Rout), AMP (pulse amplitude of intracranial pressure, ICP), dAMP (AMPplateau-AMPbaseline) and compensatory reserve index correlation coefficient between ICP and AMP (RAP). To avoid confounding factors, included patients had to be non-decompressed or with cranioplasty | 1 month previously and Rout | 6 mmHg/min/ml. Compliance was assessed using the elasticity coefficient. We also compared infusion-tested TBI patients selected for shunting versus those not selected for shunting (consultant decision based on clinical and radiological assessment and the infusion results). Finally, we used data from a group of

The objective of this work is to quantify age-related differences in the characteristics and coupling of cerebral arterial inflow and cerebrospinal fluid (CSF) dynamics. To this end, 3T phase-contrast magnetic resonance imaging blood and CSF flow data of eleven young (24 ± 3 years) and eleven elderly subjects (70 ± 5 years) with a comparable sex-ratio were acquired. Flow waveforms and their frequency composition, transfer functions from blood to CSF flows and cross-correlations were analyzed. The magnitudes of the frequency components of CSF flow in the aqueduct differ significantly between the two age groups, as do the frequency components of the cervical spinal CSF and the arterial flows. The males aqueductal CSF stroke volumes and average flow rates are significantly higher than those of the females. Transfer functions and cross-correlations between arterial blood and CSF flow reveal significant age-dependence of phase-shift between these, as do the waveforms of arterial blood, as well as ...

Ventriculo-peritoneal shunting is a surgical treatment for hydrocephalus. Complications of this procedure are not well described in dogs. The most common complication in humans is infection, which can be fatal if not diagnosed and treated quickly. We describe the magnetic resonance (MR) imaging characteristics of a shunt-associated cerebral infection in a dog. The MR features of the infection included hyperintensity of the lining of the ventricular system visible on a T2-weighted FLAIR sequence and marked linear contrast enhancement of the ependymal layer on T1-weighted sequences, similar to that described in people. ...

The ventricular spaces in the various subdivisions of the brain reflects the fact that the ventricles are the adult derivatives of the open space of the embryonic neural tube. The two lateral ventricles, situated within the cerebrum, are relatively large and C-shaped, and roughly wraps around the dorsal aspects of the basal ganglia. In the lateral ventricles of the embryo the successive generation of neurons gives rise to the 6-layered structure of the neocortex, constructed from the inside out during development. ...

An analysis is presented of 79 children under the age of 15 years suffering from benign intracranial hypertension. The commonest predisposing factor was chronic middle-ear disease which was found in 39%. Headache was the presenting symptom in 57% followed in order of frequency by earache, blurred or double vision, and vomiting. Papilloedema was present at some stage in 95%. Contrast radiography was regarded as mandatory in order to exclude a space-occupying lesion, the procedure of choice being ventriculography. A case is made for considering, as alternative procedures, echoencephalography or angiography. Treatment was limited to lumbar puncture and the prognosis was uniformly good. Nevertheless vigilance must be maintained because of the risk of permanent damage to vision from persistent papilloedema.. ...
Benign intracranial hypertension associated to blood coagulation derangements | Thrombosis Journal | Full TextBenign intracranial hypertension associated to blood coagulation derangements | Thrombosis Journal | Full Text
Benign Intracranial Hypertension (BIH) may be caused, at least in part, by intracranial sinus thrombosis. Thrombosis is normally due to derangements in blood coagulation cascade which may predispose to abnormal clotting activation or deficiency in natural inhibitors control. The aim of the study is to examine the strength of the association between risk factors for thrombosis and BIH. The incidence of prothrombotic abnormalities among a randomly investigated cohort of 17 patients with BIH, was compared with 51 healthy subjects matched for sex, age, body mass index, height and social background. The number of subjects with protein C deficiency was significantly higher in patients than in controls (3 vs 1, p | .001; Fisher Exact Test). Moderate to high titers of anticardiolipin antibodies (β2-Glycoprotein type I) were found in 8 out of 17 patients. Increased plasma levels of prothrombin fragment 1+2, fibrinopeptide A (FPA), and PAI-1 were demonstrated in patients group (5.7 ± 1.15 nM vs 0.45 ± 0.35 nM

Hydrocephalus. Hydrocephalus is a condition in which there is either an obstruction to the flow of CSF within the ventricular system or subarachnoid space (noncommunicating hydrocephalus) either due to intraventricular mass lesions or to external compression or a problem with reabsorption of CSF (communicating hydrocephalus). The type of hydrocephalus that occurs with SAH is communicating hydrocephalus. Hydrocephalus can be classified as acute, subacute, or delayed. The profiles for each are different and are briefly discussed here. With SAH, hydrocephalus develops as a result of blood in the CSF, which plugs the arachnoid villi, thus interfering with the reabsorption of CSF. Diagnosis is established on the basis of CT findings, which will reveal dilated ventricles with blood within the ventricles.. Signs and Symptoms/Treatment. The following summarizes the signs and symptoms of the three types of hydrocephalus, as well as the appropriate treatment for each.. ACUTE. ...

Abstract: : Purpose:To describe two boys with intraocular retinoblastoma with papilledema and benign intracranial hypertension and no other medical condition. Methods:Case 1 was diagnosed with bilateral retinoblastoma at 2.5 months of age. The patient was treated by enucleation of one eye and laser and cryotherapy of the other. Papilledema was seen at 6 months of age. Case 2 was diagnosed with unilateral retinoblastoma at 13 months of age. The patient was treated by enucleation of the involved eye. Papilledema was seen at the time of presentation in the other eye. Both patients were healthy males. They never had any constitutional symptoms or other medical problems and never received either chemotherapy or radiotherapy. Lumbar puncture and MRI of the head and orbits were performed in each case because of their papilledema. Results:The initial opening pressure on lumbar puncture in Case 1 was 42 cm H2O and in Case 2 was 33 cm H2O. MRI and CSF cytology were negative in both cases. In Case 1, the ...

We describe a case of recurrent coccidioidal meningitis in which a fungal biofilm on the tip of ventriculo-peritoneal shunt tubing was likely responsible for a 4-year persistence of Coccidioides immitis, despite the patients taking an adequate dosage of fluconazole. Fungal biofilms should be considered as a cause for treatment failure and fungal persistence, especially when artificial prostheses or indwelling catheters are present.
Colloid cyst - WikipediaColloid cyst - Wikipedia
A colloid cyst is a tumor containing gelatinous material in the brain. It is almost always found just posterior to the foramen of Monro in the anterior aspect of the third ventricle, originating from the roof of the ventricle. Because of its location, it can cause obstructive hydrocephalus and increased intracranial pressure. Colloid cysts represent 0.5-1% of intracranial tumors. Symptoms can include headache, vertigo, memory deficits, diplopia, behavioral disturbances and in extreme cases, sudden death. Intermittency of symptoms is characteristic of this lesion. Untreated pressure caused by these cysts can result in brain herniation. Colloid cyst symptoms have been associated with 4 variables: cyst size, cyst imaging characteristics, ventricular size, and patient age. The developmental origin is unclear, though they may be of endodermal origin, which would explain the mucin-producing, ciliated cell type. These cysts can be surgically resected, and opinion is divided about the advisability of ...

Atrial shunt revision surgeries are sometimes difficult due to venous occlusion and neck scarring. A direct approach guided by venography facilitates exposure and guarantees accurate placement of the distal catheter. Five patients with complicated histories of shunt malfunction were treated using an endoscope-assisted technique. The distal end of an atrial catheter was advanced into the atrium after having been connected to a venous catheter of a slightly smaller diameter than the one previously advanced from the femoral vein through the atrium. Once the position of the atrial catheter was confirmed fluoroscopically, the venous catheter was detached and removed. No complications developed in any patient. This endoscope-assisted technique offers three advantages: it demonstrates the patency of the jugular vein through venography, facilitates identification of the internal jugular vein in the neck, and provides a quick way to confirm that the distal end of the atrial catheter has been placed ...
Phantom model of physiologic intracranial pressure and cerebrospinal fluid dynamics. | The Interface GroupPhantom model of physiologic intracranial pressure and cerebrospinal fluid dynamics. | The Interface Group
We describe herein a novel life-size phantom model of the intracranial cavity and its validation. The cerebrospinal fluid (CSF) domains including ventricular, cysternal, and subarachnoid spaces were derived via magnetic resonance imaging. Brain mechanical properties and cranio-spinal compliance were set based on published data. Both bulk and pulsatile physiologic CSF flow were modeled. Model validation was carried out by comparisons of flow and pressure measurements in the phantom with published in vivo data of healthy subjects. Physiologic intracranial pressure with 10 mmHg mean and 0.4 mmHg peak pulse amplitude was recorded in the ventricles. Peak CSF flow rates of 0.2 and 2 ml/s were measured in the cerebral aqueduct and subarachnoid space, respectively. The phantom constitutes a first-of-its-kind approach to modeling physiologic intracranial dynamics in vitro. Herein, we describe the phantom design and manufacturing, definition and implementation of its operating parameters, as well as the ...

Third Ventricle Obstruction by Thalamic Intracerebral Hemorrhage Predicts Poor Functional Outcome Among Patients Treated with...Third Ventricle Obstruction by Thalamic Intracerebral Hemorrhage Predicts Poor Functional Outcome Among Patients Treated with...
ICH obstruction of third ventricle was defined as third ventricle compression on 1 or more axial computed tomography slices visually impeding cerebral spinal fluid flow. If the third ventricle was casted with IVH, it was scored as such. Multivariable logistic regression analyses were used to determine whether obstruction of the third ventricle predicts poor functional outcomes defined as modified Rankin score (mRS) 4-6, higher mRS, and mortality at 180 days. Models were adjusted for thalamic ICH location, ICH volume, IVH volume, age, hydrocephalus, baseline Glasgow coma scale, and percentage of low cerebral perfusion pressures during treatment.. ...
Non-invasive MRI quantification of cerebrospinal fluid dynamics in amy by Lucas R Sass, Mohammadreza Khani et al."Non-invasive MRI quantification of cerebrospinal fluid dynamics in amy" by Lucas R Sass, Mohammadreza Khani et al.
BACKGROUND: Developing novel therapeutic agents to treat amyotrophic lateral sclerosis (ALS) has been difficult due to multifactorial pathophysiologic processes at work. Intrathecal drug administration shows promise due to close proximity of cerebrospinal fluid (CSF) to affected tissues. Development of effective intrathecal pharmaceuticals will rely on accurate models of how drugs are dispersed in the CSF. Therefore, a method to quantify these dynamics and a characterization of differences across disease states is needed. METHODS: Complete intrathecal 3D CSF geometry and CSF flow velocities at six axial locations in the spinal canal were collected by T2-weighted and phase-contrast MRI, respectively. Scans were completed for eight people with ALS and ten healthy controls. Manual segmentation of the spinal subarachnoid space was performed and coupled with an interpolated model of CSF flow within the spinal canal. Geometric and hydrodynamic parameters were then generated at 1 mm slice intervals along the

Above the ventricles are smaller chambers (sections) of the heart called atria. They contract (squeeze) during the last part of diastole, and send blood down to the larger, lower ventricles. The atria have valves that close after this so blood cannot flow backward into the atria. When the ventricles are filled and the valves to the atria are closed, the ventricles contract. So, the atria and ventricles contract in sequence. The left and right atria feed blood into the ventricles. Then, the left and right ventricles contract. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the rest of the body. This is why we have a pulse. ...

Endoscopic third ventriculostomy - WikipediaEndoscopic third ventriculostomy - Wikipedia
Endoscopic third ventriculostomy (ETV) is a surgical procedure for treatment of hydrocephalus in which an opening is created in the floor of the third ventricle using an endoscope placed within the ventricular system through a burr hole. This allows the cerebrospinal fluid to flow directly to the basal cisterns, bypassing the obstruction. Specifically, the opening is created in the translucent tuber cinereum on the third ventricular floor. The ETV procedure is used as an alternative to a cerebral shunt mainly to treat certain forms of noncommunicating obstructive hydrocephalus (such as aqueductal stenosis), but since the ETV was introduced as an accepted treatment modality the range of etiologies for which it is used has grown significantly. Whereas at first it was almost exclusively performed in patients with noncommunicating obstructive hydrocephalus (e.g. aqueductal stenosis or intracerebral tumor), in the present day patients with communicating obstructive hydrocephalus (e.g. post ...

Objective: To present endoscopic techniques used as a complimentary tool in the treatment of infantile posthemorrhagic hydrocephalus. Methods: Three cases of preterm-low-birth weight infants with intraventricular hemorrhage and ventricular distention are presented. In addition to reservoir placement, the treatment included endoscopic ventricular irrigation and ventriculostomy and/or aqueductoplasty in order to treat hydrocephalus and, if possible, avoid the placement of a shunt.. Results: In one patient hydrocephalus was successfully treated by endoscopic ventricular irrigation and third ventriculostomy. No shunt was necessary in this patient. In the second patient an isolated fourth ventricle could be treated by ventricular irrigation and aqueductal stenting. Third ventriculostomy was only temporarily successful. A single ventriculo-peritoneal shunt was necessary. The third patient needed a ventriculo-peritoneal shunt after ventricular irrigation and third ventriculostomy were only temporarily ...
