To date, this is the first study to determine the potential risk factors that are predictive of shunt-dependent hydrocephalus in patients with aneurysmal SAH but without hydrocephalus upon arriving at the hospital. Differences in the relative prevalence of hydrocephalus following aneurysmal SAH vary with case ascertainment and inclusion criteria, timing and methods of neuro-imaging studies, serial follow-up neuro-imaging studies, surgical procedure, and presence of complications [1-7]. In the current study, hydrocephalus accounts for 61.9% (104/168) of all episodes, including 82 with initial hydrocephalus on admission and 22 with subsequent hydrocephalus. Such figures are higher than those of two recent studies [3, 6] and the largest study [5].. The present study examined the risk factors and outcome of shunt-dependent hydrocephalus in aneurysmal SAH patients and produced two major findings. First, the presence of intra-ventricular hemorrhage, lower mean score of Glasgow Coma Scale, higher mean ...
BACKGROUND: Hydrocephalus occurs because of an imbalance of bulk fluid flow in the brain, and aquaporins (AQPs) play pivotal roles in cerebral water movement as essential mediators during edema and fluid accumulation. AQP1 is a water channel found in the choroid plexus (CP), and AQP4 is expressed at the brain-CSF interfaces and astrocytic end feet; excessive fluid accumulation may involve expression of changes in these AQPs during various stages of hydrocephalus. OBJECTIVE: To determine the alterations of CP AQP1 expression in congenital hydrocephalus; detect hydrocephalus-induced AQP1 expression in the cortical parenchyma, ependyma, and pia mater of hydrocephalic animals; and evaluate AQP4 expression in congenital hydrocephalus through progressive stages of the condition. METHODS: We evaluated differential expression of AQPs 1 and 4 in the congenital hydrocephalus Texas rat at postnatal days 5, 10, and 26 in isolated CP and cortex by enzyme-linked immunosorbent assay, Western blot, quantitative reverse
Objective: To evaluate and identify the risk factors associated with the pathogenesis of congenital hydrocephalus in a large specific population.. Methods: An International Classification of Diseases (ICD)-9 database search of patients with congenital hydrocephalus treated at the University of Mississippi Medical Center between 1998 and 2007 was performed. All recruited patients were interviewed, assessing maternal age, onset of prenatal care, geographic location of pregnancy, maternal diabetes and chronic hypertension, pregnancy induced hypertension, pre-eclampsia, eclampsia, single or multiparous gestation, maternal alcohol, tobacco and drug use, infection and trauma during gestation, trauma or sexually transmitted disease at parturition, and other family members with hydrocephalus.. Results: In this 10 year retrospective study, several significant risk factors were identified among 596 well defined cases of congenital hydrocephalus. The identified risk factors included lack of prenatal care, ...
Acute hydrocephalus can cause neurological deterioration after aneurysmal subarachnoid hemorrhage (aSAH). Predicting which patient would require shunting is challenging. This prospective study was conducted upon twenty patients who suffered acute hydrocephalus due to subarachnoid hemorrhage of ruptured aneurysms. Surgical or non-surgical management of hydrocephalus was conducted. Glasgow Coma scale (GCS) was assessed, and hydrocephalus was graded by bicaudate index. Fisher grade was determined from CT scan. Aneurysm site was determined by conventional or CT angiography. Either surgical clipping or endovascular coiling of aneurysms was performed. Initially, 3 (15%) patients had emergency CSF diversion on admission due to poor GCS on arrival. Initially, the remaining 17 patients were managed conservatively. Five patients did not require any intervention. Twelve patients had external ventricular drainage placement, 4 were weaned, and 8 failed weaning. High bicaudate index (| 0.2) correlated with shunting.

In an effort to identify critical gaps in the prevailing knowledge of hydrocephalus, the authors formulated 10 key questions. 1) How do we define hydrocephalus? 2) How is cerebrosinal fluid (CSF) absorbed normally and what are the causes of CSF malabsorption in hydrocephalus? 3) Why do the ventricles dilate in communicating hydrocephalus? 4) What happens to the structure and function of the brain when it is compressed and stretched by the expanding ventricles? 5) What is the role of cerebrovenous pressure in hydrocephalus? 6) What causes normal-pressure hydrocephalus? 7) What causes low-pressure hydrocephalus? 8) What is the pathophysiology of slit ventricle syndrome? 9) What is the pathophysiological basis for neurological impairment in hydrocephalus, and to what extent is it reversible? 10) How is the brain of a child with hydrocephalus different from that of a young or elderly adult? Rigorous answers to these questions should lead to more effective and reliable treatments for this disorder. ...

Hydrocephalus What is hydrocephalus? Hydrocephalus is a condition in which there is a lack of absorption, blockage of flow, or overproduction of the cerebral spinal fluid (CSF) that is found inside the ventricles (fluid-filled areas) of the brain. This may result in a build up of fluid that can cause the pressure inside of the head to increase and the skull bones to expand to a larger-than-normal appearance. What causes hydrocephalus?

The causes of hydrocephalus (excess fluid in the brain) are poorly understood.. Its thought hydrocephalus present at birth (congenital hydrocephalus) may be the result of a brain defect restricting the flow of cerebrospinal fluid (CSF).. Hydrocephalus that develops in adults and children (acquired hydrocephalus) is often caused by an illness or injury that affects the brain.. Hydrocephalus that develops in older people (normal pressure hydrocephalus) may also be the result of an infection, illness or injury, but in many cases its not clear what causes the condition. ...

Long-term, prospective, longitudinal DTI studies of hydrocephalus in children are lacking. The ongoing parent project of this study is the first of its kind, to our knowledge. Its overall goal is to use DTI to evaluate white matter integrity as a noninvasive biomarker to quantify in vivo injury and posttreatment recovery in children with hydrocephalus. The data presented in the current report are the initial results derived from baseline data collected before CSF diversion surgery. Our main findings in this initial study include the following: First, the diffusion properties in children with hydrocephalus are significantly altered in several important white matter regions in the corpus callosum and internal capsule. Second, the patterns of abnormality in DTI measurements vary in different white matter regions. Patients with hydrocephalus were found to have lower FA and higher MD in the gCC and sCC, driven by the increase of RD and the relatively unchanged AD. In contrast, in the PLIC and ALIC, ...
Children with hydrocephalus have deficits in several neuropsychological domains. The most notable are motor, visuoperceptual, and visuomotor function. These deficits are multiply determined and depend on the etiology and severity of the hydrocephalus to a large extent. Corpus callosum abnormalities resulting from stretching of callosal fibers and other cortical white matter tracts are implicated as contributory to these deficits. Enlarged ventricles and associated compression of posterior cortical areas also correlate with cognitive impairment. Distinguishing which cognitive domain negatively impacts on the childs functioning and which domains influence behavior in isolation or in combination has been the subject of numerous studies. Developmentally, we know little about the emergence of neuropsychological functioning in children with hydrocephalus. Study of the effects of hydrocephalus at different stages of development is useful to clinicians and researchers interested in the impact of ...

The success of shunt surgery and ventriculostomy vary quite a bit from person to person. In general, the earlier hydrocephalus is diagnosed and treated, the more complete a persons recovery will be.. Its important for those affected by hydrocephalus as well as their families to understand that this condition can affect cognitive as well as physical development. After surgery has been performed, treatment and management should be guided by an interdisciplinary team that includes rehabilitation specialists. When connected with the right rehabilitation therapies, individuals diagnosed with this condition can lead independent lives with few restrictions.. Unfortunately, fewer than 10 medical centers in the United States currently specialize in the treatment of this condition, according to the Hydrocephalus Association. Because it involves so many variables and unknowns, doctors who do not specialize in the condition can be reluctant to take on complicated hydrocephalus cases. This means that not ...

Review A Review of Endoscopic Treatment of Hydrocephalus in Paediatric and Adult Patients Ji Min Ling, MB.ChB (UK), MMed Surgery (NUS), Rajendra Tiruchelvarayan, MBBS, FRCS (Neurosurgery) (Ireland) Department of Neurosurgery, National Neuroscience Institute, Singapore Abstract Endoscopic treatment for hydrocephalus started in the early 20th century, but could not thrive due to poor illumination and magnification of the scope. In the 1950s, ventriculoperitoneal (VP) shunt became widely acceptable as standard treatment for hydrocephalus owing to the invention of well-designed valves and discovery of silicone, a biocompatible material for manufacturing shunt catheters. However, shunting is still far from being an ideal treatment because of its associated complications such as catheter malposition, blockage, and over- or under-drainage of cerebrospinal fluid. The shunt revision rates remained high in recent series. At the same time, endoscopy has undergone tremendous improvement in the latter half ...

Often referred to as "water on the brain", hydrocephalus is a disorder in which an abnormal volume of cerebrospinal fluid (CSF) accumulates in the cranial cavity because of an imbalance between fluid production and absorption. Genetic malformations, meningitis, subarachnoid hemorrhage, stroke, trauma, tumors, or unknown causes can restrict or completely block CSF flow and generate hydrocephalus. Many cases are not due to obstruction and their cause remains unknown. Unfortunately, hydrocephalus is a debilitating disorder that afflicts 1 in 500 individuals, particularly children and the elderly. Standard treatment involves implanting a silicone catheter and valve (shunt system) to drain CSF. Although this type of treatment is usually effective in draining excess CSF temporarily, surgical revisions are often necessary due to shunt obstruction, infection, or over-drainage.. At Seattle Childrens Research Institute - Center for Integrative Brain Research, synergy and a collaborative atmosphere ...
This stock medical exhibit shows four comparative views of the head and brain of an infant describing theProgression of Hydrocephalus. The following views are illustrated: 1- Normal anatomy of the brain and ventricular system. 2- Early effects of hydrocephalus with fuid swelling of the ventricles and brain compression. 3- Late stage hydrocephalus with herniation of the brainstem out the foramen magnum of the skull. 4. Preventative measures showing shunt placement into the ventricles to drain off excessive fluid pressure and avoid a brainstem herniation.
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 ...

Hydrocephalus comes from the Greek: hydro means water, cephalus means head. Hydrocephalus is an abnormal accumulation of cerebrospinal fluid (CSF) within cavities called ventricles inside the brain. CSF is produced in the ventricles, circulates through the ventricular system, and is absorbed into the bloodstream. CSF is in constant circulation and has many important functions. It surrounds the brain and spinal cord and acts as a protective cushion against injury. CSF contains nutrients and proteins necessary for the nourishment and normal function of the brain. It carries waste products away from surrounding tissues. Hydrocephalus occurs when there is an imbalance between the amount of CSF that is produced and the rate at which it is absorbed. As CSF builds up, it causes the ventricles to enlarge, and the pressure inside the head to increase.
A Eureka Moment. Chuns laboratory specializes in the study of lipid-signaling molecules involved in the developing brain, including LPA. LPA is normally produced in the fast-growing fetal brain, and appears to be important for the normal development of neural progenitor cells. But when the researchers added abnormally high concentrations of LPA to the brains of fetal mice, they found an unexpected effect on brain development. When we looked at their condition as newborns, we were surprised to see that they uniformly had big, fluid-filled brains, said postdoctoral fellow Yun Yung, PhD. It was a Eureka moment, because we realized that LPA might help explain hydrocephalus.. Reviewing the medical literature on the condition, Chun and Yung noted that it was often linked to brain-bleeding events in the womb and typically also featured some improperly developed brain structures. Our experiments with LPA connected both sets of findings, said Yung, because LPA is involved in blood clotting and ...
Pediatric hydrocephalus is a buildup of fluid in the brain at the time of birth or during infancy, childhood or adolescence. Most often, the primary treatment for this condition is surgery to drain the fluid, and a childs outcome is often excellent.. Hydrocephalus is one of the problems pediatric neurosurgeons see most frequently. It is also known as "water on the brain," but that term is actually a misnomer. In reality, most cases of hydrocephalus represent a buildup of cerebrospinal fluid (CSF) inside the brain. Everyone continuously produces CSF, a fluid very similar to the liquid portion of blood. It contains various salts as well as other products, such as sodium and glucose. Primarily produced in the ventricles, the fluid circulates through the ventricle system and around the brain and spinal cord. Eventually, the CSF is reabsorbed over the surface of the brain into large veins, where CSF mixes with blood and is transported to the heart. This orderly cycle of CSF production, flow and ...

Benign extraaxial fluid collections of infancy: Velocity of head growth is abnormally high in the first few months of life due to the accumulation of CSF over the brains convexities. The rate of head growth then tends to normalize by 15-18 months. Physical examination and developmental status are usually normal, although occasionally a mild and transient delay occurs in motor development. Other descriptive terms for this same condition include benign subdural collections of infancy, benign communicating hydrocephalus, idiopathic pericerebral swelling, benign enlargement of the subarachnoid spaces, hypodense extracerebral fluid collections, pseudohydrocephalus megalocephaly, extraventricular obstructive hydrocephalus, benign hygromas, and subarachnoid effusion. This is generally a benign, self-limited condition that presents between the ages of 3 and 12 months and resolves spontaneously by 2-3 years of age. Surgical intervention rarely is required and is reserved for those patients who ...
Three premature infants with post-haemorrhagic hydrocephalus were treated by removing large volumes of cerebrospinal fluid with repeated lumbar punctures. After this treatment, a computerised tomographic brain scan showed that ventricle size had decreased, and subsequent head growth was normal in all three patients. The results suggest that acquired hydrocephalus in premature infants may be transient and that ventricular shunts may not be necessary in all cases.
The history of hydrocephalus treatment: The history of hydrocephalus operative treatment is very long, dating back to the times of Hippocrates (V century BC), who attempted to treat hydrocephalus by means of puncturing dilated cerebral ventricles. Along with general development of medicine, getting familiar with brain anatomy and physiology of cerebrospinal fluid circulation, and the development of new operational techniques in neurosurgery, a number of diverse hydrocephalus treatment methods had been introduced, but still it was a disease ending up with death or disability. A breakthrough moment, in which hydrocephalus treatment got revolutionized, was the day when a ventriculojugular shunt, with the use of a one-way flow stainless steel spring-ball valve, was first introduced in a six-month-old boy. Spitz and Nulsen reported this successful procedure in 1952. Since then, hydrocephalus treatment with the use of one-way shunt systems has become an approved and the most commonly used method of ...
Pediatric hydrocephalus can be prenatally diagnosed via ultrasound and involves a buildup of the cerebrospinal fluid (CSF) that cushions the brain. Early diagnosis and treatment by placement of a shunt system to divert the extra cerebrospinal fluid to an area where it can be reabsorbed is helpful. - Babies with Hydrocephalus - Children with Special Needs at BellaOnline
This study aimed to collect information on the car use and driving experiences of drivers with spina bifida and hydrocephalus and their disabled and able-bodied peers. A questionnaire was completed by 36 drivers with spina bifida and hydrocephalus (SBH) and two control groups, 36 able-bodied (AB) drivers and 14 drivers with cerebral palsy (CP). Results indicated that although those with SBH and CP took longer to learn to drive than their AB peers and reported more difficulties during the tuition period, the nature of the difficulties experienced were the same for all groups. In the first year of driving those with SBH and CP reported a lower weekly mileage but a higher number of accidents than their able-bodied peers. The SBH group were also less likely to travel on unfamiliar routes and reported greater difficulties with route planning and route following. Many drivers from both disabled and able-bodied groups reported difficulties with parking and reversing during the first year of driving and would

hydrocephalus; hydro; cephalus; spina; bifida; shunt; blockage; Arnold; chiari; ventricles; meningitis; head; injury; valve; CFS; cerebral; spinal; fluid; learn; learning; behaviour; Inside every brain there is a clear fluid called cerebrospinal fluid (CSF). This fluid is made inside spaces in the brain, called ventricles. The CSF flows out over the surface of the brain and down the spinal cord before being absorbed into the bloodstream. CSF provides nutrients to the brain and spinal cord and removes waste products. It also acts as a cushion to protect the brain and spinal cord. Hydrocephalus is when children have too much CSF in the ventricles in their brain, and the ventricles get bigger and begin to cause problems. Since the fluid is still being made by the brain, the build-up of CSF will cause pressure to rise inside the brain. This can then lead to signs of raised pressure and eventually damage to the brain, if not treated. ...
