Treatment of hydrocephalus secondary to cryptococcal meningitis by use of shunting. (1/310)

Hydrocephalus can be associated with increased morbidity and mortality in cryptococcal meningitis if left untreated. Both ventriculoperitoneal and ventriculoatrial shunting have been used in persons with cryptococcosis complicated by hydrocephalus, but the indications for and complications, success, and timing of these interventions are not well known. To this end, we reviewed the clinical courses of 10 non-human immunodeficiency virus-infected patients with hydrocephalus secondary to cryptococcal meningitis who underwent shunting procedures. Nine of 10 patients who underwent shunting had noticeable improvement in dementia and gait. Two patients required late revision of their shunts. Shunt placement in eight patients with acute infection did not disseminate cryptococcal infection into the peritoneum or bloodstream, nor did shunting provide a nidus from which Cryptococcus organisms proved difficult to eradicate. Shunting procedures are a safe and effective therapy for hydrocephalus in patients with cryptococcal meningitis and need not be delayed until patients are mycologically cured.  (+info)

Link between the CSF shunt and achievement in adults with spina bifida. (2/310)

OBJECTIVES: A few enterprising adults with shunt treated spina bifida live independently in the community, have a job in competitive employment, and drive to work in their own car. By contrast others with similar disability but lacking their motivation remain dependent on care and supervision. The aim of this study was to identify events in the history of their shunt which may have influenced their subsequent achievement. METHODS: Between June 1963 and January 1971 117 babies born in East Anglia with open spina bifida had their backs closed regardless of the severity of their condition. When reviewed in 1997 every case was ascertained. Sixty had died and the 57 survivors had a mean age of 30. These were assigned to two groups: achievers and non-achievers, according to their attainments in independence, employment, and use of a car. RESULTS: Of the 57 survivors nine had no shunt and eight of these were achievers. All were of normal intelligence (IQ>/=80) and only one was severely disabled. Of the 48 with shunts only 20 were achievers (OR 11.2, 95% confidence interval (95% CI) 1.3-96.8). Lack of achievement in these 48 was associated with revisions of the shunt, particularly when revisions were performed after the age of 2. Sixteen patients had never required a revision and 11 (69%) were achievers; 10 had had revisions only during infancy and five (50%) were achievers; 22 had had revisions after their second birthday and only four (18%) were achievers (p<0.001). Elective revisions were not performed in this cohort and in 75% of patients revisions had been preceded by clear symptoms of raised intracranial pressure. CONCLUSION: Revisions of the shunt, particularly after the age of 2, are associated with poor long term achievement in adults with spina bifida.  (+info)

Effect of cerebrospinal fluid shunting on experimental syringomyelia: magnetic resonance imaging and histological findings. (3/310)

The histological changes associated with syringomyelia after reduction of the syrinx size were investigated after cerebrospinal fluid shunting in experimental syringomyelia in the rabbit. Five weeks after syringomyelia was induced by the injection of kaolin into the cisterna magna in Japanese white rabbits, ventriculosubgaleal shunting or syringoepidural shunting were performed. After 1 week magnetic resonance (MR) imaging and histological examination were then carried out. Five of 11 shunted animals showed postoperative reduction of syrinx size on MR imaging. Grossly, some specimens showed cavity collapse and parenchymal healing, and others showed a small residual syrinx in the dorsal horn. The most dramatic histological changes occurred in the gray matter. Specimens with syrinx collapse showed rarefaction and tearing of the gray matter, with mild glial reaction. The edematous gray matter showed both degeneration and regeneration, with neuronal processes surrounded by edema fluid. Reactive astrocytes were observed mainly at the margin of the residual syrinx. Some astrocytic processes invested the extraaxonal space and gray matter lacked supportive tissue. Greater reduction of the syrinx after shunting operation was correlated with more regeneration and less degeneration, and the white matter was edematous and histological changes were milder. Syrinx shrinkage occurred after shunting in this experimental model of syringomyelia. The selective vulnerability of gray matter even after shunting may explain discrepancies between imaging findings and clinical features in this disease. The study supports the potential benefit from early treatment, considering the associated morphological findings of regeneration.  (+info)

Specific patterns of cognitive impairment in patients with idiopathic normal pressure hydrocephalus and Alzheimer's disease: a pilot study. (4/310)

OBJECTIVES: Eleven patients with idiopathic normal pressure hydrocephalus (NPH) were selected from an initial cohort of 43 patients. The patients with NPH fell into two distinctive subgroups: preshunt, group 1 (n=5) scored less than 24 on the mini mental state examination (MMSE) and were classified as demented and group 2 (n=6) scored 24 or above on the MMSE and were classified as non-demented. METHODS: All patients were neuropsychologically assessed on two occasions: preshunt and then again 6 months postshunt. Group 1 completed the mini mental state examination (MMSE) and the Kendrick object learning test (KOLT). In addition to the MMSE and KOLT, group 2 completed further tasks including verbal fluency and memory and attentional tasks from the CANTAB battery. Nine of the 11 patients also underwent postshunt MRI. RESULTS: Group 1, who, preshunt, performed in the dementing range on both the MMSE and KOLT, showed a significant postoperative recovery, with all patients now scoring within the normal non-demented range. Group 2, although showing no signs of dementia according to the MMSE and KOLT either preshunt or postshunt, did show a specific pattern of impairment on tests sensitive to frontostriatal dysfunction compared with healthy volunteers, and this pattern remained postoperatively. Importantly, this pattern is distinct from that exhibited by patients with mild Alzheimer's disease. Eight of the nine patterns of structural damage corresponded well to cognitive performance. CONCLUSIONS: These findings are useful for three main reasons: (1) they detail the structural and functional profile of impairment seen in NPH, (2) they demonstrate the heterogeneity found in this population and show how severity of initial cognitive impairment can affect outcome postshunt, and (3) they may inform and provide a means of monitoring the cognitive outcome of new procedures in shunt surgery.  (+info)

Dandy-Walker syndrome successfully treated with cystoperitoneal shunting--case report. (5/310)

A neonate presented with Dandy-Walker syndrome manifesting as a large posterior cranial fossa cyst, aplasia of the lower cerebellar vermis, and elevation of the confluence of the sinuses but without hydrocephalus. A cystoperitoneal shunt was placed at one month after birth. The cyst diminished in size, and marked development of the cerebellar hemispheres and descent of the confluence of sinuses were observed, but not vermis development. The primary pathology of Dandy-Walker syndrome is posterior cranial fossa cyst formation due to passage obstruction in the fourth ventricle exit area and aplasia of the lower cerebellar vermis. The first choice of treatment in patients with Dandy-Walker syndrome in whom the cerebral aqueduct is open is cystoperitoneal shunt surgery, regardless of the presence or absence of hydrocephalus.  (+info)

Prediction of effectiveness of shunting in patients with normal pressure hydrocephalus by cerebral blood flow measurement and computed tomography cisternography. (6/310)

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)

MR imaging of the hippocampus in normal pressure hydrocephalus: correlations with cortical Alzheimer's disease confirmed by pathologic analysis. (7/310)

BACKGROUND AND PURPOSE: MR studies have shown hippocampal atrophy to be a sensitive diagnostic feature of Alzheimer's disease (AD). In this study, we measured the hippocampal volumes of patients with a clinical diagnosis of normal pressure hydrocephalus (NPH), a potentially reversible cause of dementia when shunted. Further, we examined the relationship between the hippocampal volumes and cortical AD pathologic findings, intracranial pressure, and clinical outcomes in cases of NPH. METHODS: We measured hippocampal volumes from 37 patients with a clinical diagnosis of NPH (27 control volunteers and 24 patients with AD). The patients with NPH underwent biopsy, and their clinical outcomes were followed for a year. RESULTS: Compared with those for control volunteers, the findings for patients with NPH included a minor left-side decrease in the hippocampal volumes (P < .05). Compared with those for patients with AD, the findings for patients with NPH included significantly larger hippocampi on both sides. Although not statistically significant, trends toward larger volumes were observed in patients with NPH who had elevated intracranial pressure, who benefited from shunting, and who did not display cortical AD pathologic findings. CONCLUSIONS: Measurements of hippocampal volumes among patients with a clinical diagnosis of NPH have clear clinical implications, providing diagnostic discrimination from AD and possibly prediction of clinical outcome after shunting.  (+info)

Indications for shunting in patients with idiopathic normal pressure hydrocephalus presenting with dementia and brain atrophy (atypical idiopathic normal pressure hydrocephalus). (8/310)

The indications for shunt operation in patients with idiopathic normal pressure hydrocephalus accompanied by brain atrophy (atypical idiopathic normal pressure hydrocephalus: AINPH) were investigated in 25 patients who satisfied the diagnostic criteria and underwent ventriculoperitoneal (VP) shunting. All patients had no apparent history of intra- or extracranial disease; dementia and gait disturbance as the main complaints; moderate to severe cerebral atrophy and ventricular dilatation and at least periventricular low density around the anterior horn on computed tomography; normal cerebrospinal fluid (CSF) pressure and filling of ventricles or cortical surface space with contrast medium at 24 hours on cisternography. The 15 male and 10 female patients were aged 47-83 years (mean 60.4 years). VP shunting was effective in 12 improved patients and not effective in 13 unimproved patients according to NPH grading. Pathological pressure wave on epidural pressure monitoring was observed in eight of 12 improved patients, but none of 13 unimproved patients. CSF outflow resistance was 35.33 +/- 11.16 mmHg/ml/min in improved patients and 9.12 +/- 3.51 mmHg/ml/min in unimproved patients. Preoperative serum alpha-1-antichymotrypsin value (alpha-1-ACT) was 42.02 +/- 8.64 mg/dl in improved patients and 61.72 +/- 11.03 mg/dl in unimproved patients. Alpha-1-ACT over 55 mg/dl occurred only in unimproved patients. Cerebral arteriovenous difference of oxygen content value (c-AVDO2) before and after surgery was 6.34 +/- 0.9 ml% and 5.91 +/- 0.78 ml% in improved patients and 4.75 +/- 1.85 ml% and 4.81 +/- 1.73 ml% in unimproved patients, respectively. The two cases with preoperative c-AVDO2 value over 8.5 ml% were both unimproved. Mean cerebral blood flow value before and after surgery was 23.51 +/- 4.20 ml/100 g/min and 45.22 +/- 8.11 ml/100 g/min in improved patients and 21.77 +/- 5.12 ml/100 g/min and 24.82 +/- 4.97 ml/100 g/min in unimproved patients, respectively. Cerebral atrophy in improved patients is caused by a cerebral circulation disturbance defined as a cerebral blood flow of penumbra or more due to cerebral arteriosclerosis, etc. A flow-chart of indications of shunt surgery for AINPH was prepared based on the results of the present study.  (+info)

INTRODUCTION Previous prospective study in our unit had shown that the use of dual antibiotic prophylaxis in patients with external ventricular drain was associated with decreased incidence of cerebrospinal fluid infection but complicated with opportunistic extracranial infection. In recent years, cerebrospinal fluid shunt catheters impregnated with antimicrobial agents have become available. Theoretically, these catheters provide antibiotic prophylaxis locally without the associated complications of systemic opportunistic infection. METHODS We carried out a prospective randomized, controlled clinical trial in a regional neurosurgical center in Hong Kong. We recruited patients admitted for emergency neurosurgical operation after informed consent was obtained from next-of-kin. Eligible patients were randomized to receive an antibiotic-impregnated ventricular catheter or plain ventricular catheter Dual prophylactic antibiotic coverage was given to the patients randomized for plain ventricular catheter
Shunt nephritis is a rare disease of the kidney that can occur in patients being treated for hydrocephalus with a cerebral shunt. It usually results from an infected shunt that produces a long-standing blood infection, particularly by the bacterium Staphylococcus epidermidis. Kidney disease results from an immune response that deposits immune complexes in the kidney. The most common signs and symptoms of the condition are blood and protein in the urine, anemia, and high blood pressure. Diagnosis is based on these findings in the context of characteristic laboratory values. Treatment includes antibiotics and the prompt removal of the infected shunt. Over half of individuals with shunt nephritis recover completely; most of the remainder have some degree of persistent kidney disease. Shunt nephritis is a rare condition affecting males and females of all ages. It occurs in approximately 0.7-2.3% of patients with shunt infections. Approximately 12% of ventriculoatrial shunts become infected, with ...
A cerebrospinal fluid shunt system comprises a brain ventricular catheter for insertion into the brain ventricle so as to drain cerebrospinal fluid from the brain ventricle. The system also comprises a sinus sagittalis catheter for insertion into the sinus sagittalis for feeding the cerebrospinal fluid into sinus sagittalis. A shunt main body is connected at one end thereof to the brain ventricle catheter and at another end thereof to the sinus sagittalis catheter. The shunt main body can provide fluidic communication between the brain ventricle catheter and the sinus sagittalis catheter. The system further comprises a tubular flow passage restricting member defined within the shunt main body. The tubular flow passage restricting member defines a resistance to flow of 8-12 mm Hg/ml/min.
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 ...
The researchers saw no significant association between preoperative elevated PT levels and hemorrhagic complications -- a finding that suggests the "value of preoperative PT testing is limited in patients in whom a normal history can be ascertained.". They noted that postoperative PT control is necessary in all patients, and researchers need better tests to identify those at risk of hemorrhagic complications.. Surgery Specific Evaluations. The special issue also includes reports on surgical time-outs and checklists in specific areas, including intra-operative neuromonitoring changes and in the intra-operative MRI suite.. Four studies looked at patterns of adverse events in four areas of neurosurgery: cerebrospinal fluid shunt surgery, endovascular neurosurgery, open cerebrovascular neurosurgery, and intracranial neoplasm surgery.. And an Italian team led by Paolo Ferroli, MD, of the Fondazione Instituto Neurologico in Milan, found that implementing an aviation checklist for incident reporting ...
Shunts are the standard treatment for hydrocephalus, but they are prone to complications, with up to 16% of shunts requiring revision within one month.17 Some consider that a high CSF protein plays a part in shunt failure,1-6 but recent work has invalidated most theories on possible mechanisms.7-9However, the possibility of protein deposition obstructing the shunt lumen has not yet been investigated.. In 1963 Scarff stated that "...cerebrospinal fluid is laden with protein and minerals, which are gradually deposited as particulate matter on the inner surfaces of the tubes and valves, contributing to their obstruction or malfunction".6 This statement, from a clinical review, was made without any supporting evidence, but is still accepted by many. Furthermore, as far as can be determined, no attempt has been made to verify or refute the statement.. The only material present in sufficient quantities to occlude the catheters in this series was choroid plexus. Several authors, analysing material ...
Background. Data on infections associated with cerebrospinal fluid (CSF) shunts among adults are limited. Therefore, we performed a retrospective study of shunt-associated infections in adults.. Methods. Patients aged ⩾12 years with infections associated with CSF shunts and admitted to our institution (University Hospital Basel, Basel, Switzerland) from January 1996 through December 2006 were included retrospectively. Hospital charts were reviewed, and follow-up was performed by assessment of later hospitalizations and telephone contact with patients, their families, and general practitioners.. Results. Seventy-eight episodes of infection associated with ventriculoperitoneal shunt (65 episodes), ventriculoatrial shunt (7), lumboperitoneal shunt (5), and central nervous system reservoir (1) were included. Median patient age was 50 years (range, 12-80 years); 49 (63%) of the patients were men. Most infections (48 [62%]) manifested within 1 month after shunt surgery. Fever was present in 61 ...

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 ...
Spinal fluid shunt. In another type of surgery, your doctor inserts a long, thin tube (shunt) into your brain or lower spine to help drain excess cerebrospinal fluid. The tubing is burrowed under your skin to your abdomen, where the shunt releases the excess fluid.. A shunt is generally considered only if other treatments havent relieved your condition. Shunts can clog and often require other surgeries to keep them working. Complications can include low-pressure headaches and infections.. ...
CONCLUSION: These preliminary results suggest that a uniform and drastic sterile surgical technique for shunt placement: (1) can be rigidly applied on a routine basis; (2) can lower the early SI rate below 1%; (3) might have a stronger impact to reduce SI than using antibiotic-impregnated catheters and optimizing the operative environment such as using laminar airflow and reducing the non-surgical staff. This last issue will be evaluated further in the present ongoing protocol ...
Broad range real-time PCR: Although not widely available, real-time PCR is a laboratory diagnostic tool that is particularly useful because it can rapidly (less than 4 hours) identify gram-positive and gram-negative bacterial strains that otherwise would have been impossible to isolate due to initiated antibiotic therapy. Its usefulness has been emphasized in initiating and interrupting antibiotic therapy, particularly in patients who have experienced a previous shunt infection. Moreover, bacterial DNA load can be monitored by this technique to determine the impact of antibiotic therapy (13). However, this technique lacks the ability to define antibiotic sensitivity patterns and can also lead to false positive results (13, 24 ...

Idiopathic Normal Pressure Hydrocephalus (INPH) is a condition affecting gait, cognition and continence. Radiological examination reveals enlarged ventricles of the brain. A shunt that drains CSF from the ventricles to the abdomen often improves the symptoms. Much research on INPH has been focused on identifying tests that predict the outcome after shunt surgery. As part of this quest, there are attempts to find measurement methods of intracranial parameters that are valid, reliable, tolerable and safe for patients.. Todays technologies for intracranial pressure (ICP) measurement are invasive, often requiring a burr-hole in the skull. Recently, a method for non-invasive ICP measurements was suggested: the Pulsatile Index (PI) calculated from transcranial Doppler data assessed from the middle cerebral artery. In this thesis the relation between PI and ICP was explored in INPH patients during controlled ICP regulation by lumbar infusion. The confidence interval for predicted ICP, based on ...
Background: There is little knowledge about the factors influencing the long-term outcome after surgery for idiopathic normal pressure hydrocephalus (iNPH).. Objective: To evaluate the effects of reoperation due to complications and of vascular comorbidity (hypertension, diabetes, stroke and heart disease) on the outcome in iNPH patients, 2-6 years after shunt surgery.. Methods: We included 979 patients from the Swedish Hydrocephalus Quality Registry (SHQR), operated on for iNPH during 2004-2011. The patients were followed yearly by mailed questionnaires, including a self-assessed modified Rankin Scale (smRS) and a subjective comparison between their present and their preoperative health condition. The replies were grouped according to the length of follow-up after surgery. Data on clinical evaluations, vascular comorbidity, and reoperations were extracted from the SHQR.. Results: On the smRS, 40% (38-41) of the patients were improved 2-6 years after surgery and around 60% reported their general ...

Abstract. Cryptococcal meningitis may have long-term morbidity and requires a permanent cerebrospinal fluid shunt. This study aimed to evaluate the risk factors and create a predictive model for permanent shunt treatment in cryptococcal meningitis patients. This was a retrospective analytical study conducted at Khon Kaen University. The study period was from January 2005 to December 2015. We enrolled all adult patients diagnosed with cryptococcal meningitis. Risk factors predictive for permanent shunting treatment were analyzed by multivariate logistic regression analysis. There were 341 patients diagnosed with cryptococcal meningitis. Of those, 64 patients (18.7%) were treated with permanent shunts. There were three independent factors associated with permanent shunt treatment. The presence of hydrocephalus had the highest adjusted odds ratio at 56.77. The resulting predictive model for permanent shunt treatment (y) is (−3.85) + (4.04 × hydrocephalus) + (2.13 × initial cerebrospinal fluid (CSF)
Staphylococcus epidermidis is a leading cause of hospital-associated infections, including those of intravascular catheters, cerebrospinal fluid shunts, and orthopedic implants. Multiple biofilm matrix molecules with heterogeneous characteristics have been identified, including proteinaceous, polysaccharide, and nucleic acid factors. Two of the best-studied components in S. epidermidis include accumulation-associated protein (Aap) and polysaccharide intercellular adhesin (PIA), produced by the enzymatic products of the icaADBC operon. Biofilm composition varies by strain as well as environmental conditions, and strains producing PIA-mediated biofilms are more robust. Clinically, biofilm-mediated infections occur in a variety of anatomical sites with diverse physiological properties. To test the hypothesis that matrix composition exhibits niche specificity, biofilm-related genetic and physical properties were compared between S. epidermidis strains isolated from high-shear and low-shear ...
Background/objective: Little is known about the long-term clinical course and management of patients with normal pressure hydrocephalus (NPH) treated by cere-brospinal fluid (CSF) shunting. Methods: We retrospectively reviewed records of 55 patients diagnosed with idiopathic NPH (INPH) and treated with CSF shunts, all of whom were followed for more than 3 years after the original shunt surgery. At each annual follow-up visit, the patient was assessed by Folstein Mini Mental State Examination, detailed clinical evaluation of gait and assessment of headache, cognition, gait or urination, as assessed by the patient and relatives. Results: The mean duration of follow-up was 5.9 ± 2.5 years. There was an overall sustained improvement among all symptoms. Gait showed the highest maintenance of improvement over baseline (83% at 3 years and 87% at the last analysed follow-up of 7 years), cognition showed intermediary improvement (84% and 86%, respectively), and urinary incontinence showed the least ...

Purpose: Normal Pressure Hydrocephalus (NPH) is a clinical diagnosis with no formal definition. Textbooks describe NPH as a clinical triad of gait abnormality, dementia, and urinary incontinence. Few patients present with all three symptoms, forcing the clinician to rely on a "preponderance of evidence" approach, which involves weighing triad symptoms with radiological findings, Cerebrospinal Fluid (CSF) opening pressure, response to Tap Test, external lumbar CSF drainage, lumbar infusion, and finally shunting. Radiological findings in NPH are limited to enlarged ventricles out of proportion to sulcal atrophy, callosal angles greater than 40 degrees, and ventricles with Evans ratios greater than 0.3. When radiologists evaluate suspected NPH patients they are limited to excluding disease, as opposed to searching for any particular finding. In this study we used Diffusion Tensor Imaging (DTI) to determine if differences can be identified on a group basis between NPH and normal groups to see if ...

Patients with idiopathic normal pressure hydrocephalus (INPH) have a disturbance in the cerebrospinal fluid (CSF) system. The treatment is neurosurgical - a shunt is placed in the CSF system. The infusion test is used to assess CSF system dynamics and to aid in the selection of patients that will benefit from shunt surgery. The infusion test can be divided into three parts: a mathematical model, an infusion protocol and a parameter estimation method. A non-linear differential equation is used to mathematically describe the CSF system, where two important parameters are the outflow conductance (Cout) and the Pressure Volume Index (PVI). These are used both for clinical and research purposes. The analysis methods for the non-linear CSF system have limited the infusion protocols of presently used infusion investigations. They come with disadvantages such as long investigation time, no estimation of PVI and no measure of the reliability of the estimates.. The aim of this dissertation was to develop ...

Leucine-rich alpha-2-glycoprotein 1 (LRG1) is a member of the leucine-rich repeat (LRR) family of proteins that are involved in protein-protein interaction, signal transduction, and cell adhesion and development. LRG1 was first identified as a trace component in human serum and was characterized as a marker for early neutrophilic granulocyte differentiation. LRG1 contains a 24-amino acid consensus sequence, the leucine-rich repeat, which is found in other LRG-family proteins. LRG is expressed in primary human neutrophils, and its expression is upregulated during neutrophilic granulocyte differentiation of human and murine cell lines. High levels of LRG1 have been reported in the cerebrospinal fluid of patients with idiopathic normal pressure hydrocephalus (iNPH), and LRG1 measurement can be useful to distinguish iNPH from early-stage Alzheimers disease symptoms ...

Objective: The diagnosis and management of idiopathic normal-pressure hydrocephalus (iNPH) remains controversial, particularly in selecting patients for shunt insertion. Diagnostic criteria target the pathology of the dynamics of the cerebrospinal fluid (CSF), however the effectiveness in predicting shunt success has room for improvement. The aim of our study was to systematically assess the influence of the co-morbidity determining the benefit from shunt surgery.. Methods: Between 1997 and 2006 one hundred thirty-four patients suffering from iNPH were treated with a ventriculo-peritoneal shunt with a gravity-controlled valve. The coincident disease processes were recorded. Shunt outcome was assessed at 2 years postsurgery in 116 patients (follow up rate 87%). The results of this follow-up examination (Kiefer Score, NPH Recovery Rate) were compared with the preoperative Co-Morbidity Index (CMI).. Results: Of the 134 patients 76 (56.7%) had a CMI of 0 - 3 and 58 patients (43.3%) had a CMI of 4-8. ...
An overlying problem with shunting cerebrospinal fluid (CSF) is that there is no way to directly measure the volume being drained through a shunt once it has been implanted. Therefore, it becomes very difficult to determine if the shunt is working properly. If the patients symptoms remain unchanged, the shunt may not be draining fluid, the pressure setting on the shunt may need to be changed, or the patient may simply be unresponsive to shunt treatment. The objective is to develop a prototype shunt device which is capable of measuring, recording, and controlling the amount of CSF that passes through it on a daily basis. By using a positive displacement pump and controlling the stroke frequency, a volume of fluid similar to CSF (water) is controlled, measured, and recorded. If the volume of CSF being drained could be measured and controlled, this would make troubleshooting much easier. By using a bicorporeal device, power supply, and pumping device, it is hypothesized that shunting can be ...
MEDICAL: A comprehensive background about Normal Pressure Hydrocephalus (NPH) ― the treatable dementia [Cover photo: Cross-section images of (left) brain with extra fluid; (right) normal brain] For ten years, we were told that my father had Parkinsons disease. Turns out, what he actually had was something called Normal Pressure Hydrocephalus (NPH) or, simply, water in the brain. The good news is that NPH is treatable, and a shunt implant can reverse the symptoms suffered by those who have NPH. Unfortunately, NPH symptoms mimic the fatal dementias of Parkinsons and Alzheimers, so many older people remain misdiagnosed or undiagnosed. Words: 11,389

An intracranial ventricular shunt is a device (catheter/tube) used to drain an excess of cerebrospinal fluid from the brain. (Cerebrospinal fluid is a clear body fluid released into the subarachnoid space; the subarachnoid space surrounds the brain and the spinal cord.) Patients with intracranial ventricular shunts are prone to infection. Some doctors give either antibiotic drugs or use antibiotic-impregnated devices to reduce the risk of infection. Our review included randomized controlled trials that compared the incidence of shunt infection in patients who were given preventive antibiotic therapy with those who did not receive these drugs. We also included trials comparing antibiotic-impregnated shunt systems with those who received non-antibiotic impregnated shunts. We included seventeen trials in our review. Although the available data does not provide much detail on mortality or the adverse events caused by antibiotics (an adverse event is an incident in which harm resulted to a person ...

Sepsis with a previously undescribed species of Corynebacterium was documented in four patients. All patients had predisposing illness at the time of infection, three patients having leukemia in relapse and one having a porencephalic cyst and a ventriculoatrial shunt. The isolates from blood cultures had a characteristic metallic sheen when grown on blood agar. They were resistant to most antibiotics tested, including the penicillins, but were uniformly sensitive to vancomycin. Common biochemical characteristics, the metallic sheen, and the unusual antibiotic sensitivity pattern suggest that these isolates comprise a new species or group of closely related species of Corynebacterium that is capable of infection in man. ...
Albany, New York, April 28, 2017: CSF shunts and CSF drainage systems are used to manage or divert the CSF flow in the body away from the ventricles in a controlled manner, thereby providing an alternative pathway. Hydrocephalus is the abnormal accumulation of CSF within the brain cavities called ventricles (space near the spine). It occurs due to an imbalance in the formation and absorption rate of the fluid. This results in ventricle enlargement and increased pressure inside the head. "Global Cerebrospinal Fluid (CSF) Management Devices Market Forecast Report" has been prepared based on an in-depth market analysis with inputs from industry experts. The report covers the market landscape and its growth prospects over the coming years. The report also includes a discussion of the key vendors operating in this market.. ...

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 ...

There is no known way to prevent or cure hydrocephalus. If obstruction is found on CT scan due to a tumor or cyst, it can be excised by a neurosurgeon to re-establish the CSF pathway. In other situations the most effective treatment is insertion of a shunt (at a known pressure gradient). The shunt is a hollow silicone tube, placed into the ventricular system, diverting the CSF flow to the peritoneal cavity of the abdomen (VP shunt). If abdominal cavity is unable to absorb the fluid due to some disease viz. TB or cyst, the shunt can be placed via the jugular vein to reach the right atrium of heart (VA shunt). Shunts can also be placed in the pleural (chest) cavity ...
Thank you so much for your story it gives me some hope. I too cried ALOT I was completely devastated and wishing that I wouldnt have done the surgery, I have not lost complete feeling but its all asleep and abnormal sensations so everything that I do feel is not a real sensation like sometimes I feel like my leg and butt are wet and there is pins and needles all the time, it feels like sandpaper when I wipe myself its horrible. My surgery experience was also hell morphine didnt work when I first woke they gave me three doses through the iv then a straight shot into my thigh muscle, still no relief so I was put on diladen that seemed to work better just knocked me out, I was mostly on percocet and soma. They did my laminectomy from T-7 to T-10 My doc said that was a good spot because it was above the area that controls bladder and bowel functions and below the area that controls the arms but I also get alot of muscle spasms by my insicion especially when I use my arms alot.

I posted here back in March, and you all were very helpful. Am hoping you can offer guidance on a NS dynamics question. NS 1 diagnosed me with communicating hydrocephalus in 2008, but now over-draining VP shunt (lateral & 3rd slit-ventricle); he suspects high-flow occult leak. Referred me to NS 2 (different hospital system) for 2nd opinion/consult. NS 2 says over-shunted, slit-ventricle, no occult leak & remove entire shunt system. Neither recommends myelogram because of additional leak site
Yesterday, Poppy went into surgery to have her vp shunt revised.

Does anyone have experience with using a pump where the person also has a VP (ventricular peritonial) shunt? Im a dietitian working in a small clinic, and weve been referred a child with a VP shunt for pump assessment. Thanks for sharing your experience. Janet von Weiler ____________________________ I have lots of experience with V-P shunts and have been pumping myself for the past 2 years. Because of the danger of bacteremia from a pump site I would caution against the use of a pump in diabetic children. especially if the child is shunt dependant. it is easy to get a bacteremia from the pump which might colonize the shunt hardware and result in the need to remove the vp shunt since they are not easily rendered sterile with parenteral antibiotics. As physicians have said thruout the years, First do no harm. Primum non nocere! no matter how careful you are a site infection can be deadly in this kind of case. this is a lawsuit waiting to happen!!! spot ...

BACKGROUND AND PURPOSE: Increased CSF stroke volume through the cerebral aqueduct has been proposed as a possible indicator of positive surgical outcome in patients with idiopathic normal pressure hydrocephalus; however, consensus is lacking. In this prospective study, we aimed to compare CSF flow parameters in patients with idiopathic normal pressure hydrocephalus with those in healthy controls and change after shunt surgery and to investigate whether any parameter could predict surgical outcome. MATERIALS AND METHODS: Twenty-one patients with idiopathic normal pressure hydrocephalus and 21 age- and sex-matched healthy controls were prospectively included and examined clinically and with MR imaging of the brain. Eighteen patients were treated with shunt implantation and were re-examined clinically and with MR imaging the day before the operation and 3 months postoperatively. All MR imaging scans included a phase-contrast sequence. RESULTS: The median aqueductal CSF stroke volume was ...
OBJECTIVE: To provide a simple and reliable method for the diagnosis of ventriculoperitoneal shunt malfunction.. METHODS: A total of 14 participants were enrolled in this study, consisting of 7 patients with suspected shunt malfunction and 7 control cases with apparent normal drainage. In all cases, 0.1 mL of 5% glucose solution was injected into the reservoir and 0.1 mL of cerebrospinal fluid was withdrawn from the reservoir 20 minutes later to measure glucose concentration.. RESULTS: The glucose concentration in cerebrospinal fluid of the shunt malfunction group was greater than that of the control group (P , 0.05).. CONCLUSIONS: The proposed method is reliable, safe, and relatively simple for the diagnosis of ventriculoperitoneal shunt malfunction and provides a reference for treatment.. ...
A 67-year-old man presented with worsening dyspnea 1 month after double mitral and tricuspid valve repair. Physical examination revealed high-pitched holosystolic murmur across the precordium. Two-dimensional transthoracic echocardiography revealed an abnormal, high velocity left-to-right shunt across the basal interventricular septum (jet velocity of 4.3 m/s), along with significant mitral regurgitation. Real-time 3-dimensional transesophageal echocardiography showed a ventriculoatrial shunt above the septal leaflet of the tricuspid valve, consistent with a Gerbode defect (A to D; Online Videos 1 and 2). The mitral ring (triangle) was dehisced and avulsed anteriorly with resultant severe mitral regurgitation (F, G; Online Videos 3 and 4). The intraoperative findings confirmed the 3-dimensional transesophageal echocardiography description of the lesions (E, H). The patient then underwent mitral valve replacement and repair of the defect with good outcomes. This case illustrates Gerbode defect ...
A 60-year-old female with a history of ventriculoperitoneal shunt (VPS) placement three years prior presented with a painful abdominal wall mass. The patient denied fevers, nausea, vomiting, headaches, or dizziness. Physical exam revealed an afebrile, well-appearing female with a raised, erythematous, fluctuant mass on the right lower abdominal wall. She had no abdominal tenderness otherwise. Labs were unremarkable. A bedside ultrasound revealed a complex fluid collection over the area of fluctuance that tracked along the course of the VPS tubing into the abdomen. Plan for incision and drainage was deferred. Neurosurgery was consulted. The neurosurgeon attempted to tap the shunt but encountered very high resistance. The patient was admitted for intravenous antibiotics for VPS infection and malfunction.. VPSs are neurosurgically implanted devices used to treat hydrocephalus by shunting cerebral spinal fluid from the lateral ventricles of the brain into the peritoneum. Shunt infections, including ...

Title. Parents involvement in decisions when their child is admitted to hospital with suspected shunt malfunction: study protocol. Aim. This paper outlines the protocol for a study aimed at exploring parents involvement during professional-parent interactions and decisions about their childs care in the context of suspected shunt malfunction. Background. Hydrocephalus is a long-term condition treated primarily by the insertion of a shunt that diverts fluid from the brain to another body compartment. Shunts frequently malfunction, and parents of children with shunted hydrocephalus are responsible for recognizing and responding to shunt complications. Parents feel that interactions with professionals when they seek healthcare advice for their child do always not encourage active participation in care decisions. Methods. The study design is based on qualitative methodologies: a combination of conversation analysis applied to consultation recordings of professional-parent interactions when a ...
Normal-pressure hydrocephalus (NPH) was the first treatable type of dementia everdescribed. Hakim and Adams described the entity they called normal pressurehydrocephalus in 1965 (Hakim & Adams, 1965). Cerebrospinal fluid shunting forhydrocephalus was the first wide treatment available for the disease. In the followingyears, an initially uncritical enthusiasm for cerebrospinal fluid (CSF) shunting wasgradually dampened because of the underdeveloped shunt technology, low clinicalsuccess rates, and frequent complications (Dippel & Habbema, 1993).The most frequent complication is ventricular catheter obstruction, which may accountfor 50 to 80% of newly inserted shunts (Bergsneider et al., 2006). Although many factorscontribute to this (Harris & McAllister, 2012), the main one is related to flowcharacteristics of the catheter within the hydrocephalic brain (Harris & McAllister, 2012;Lin, Morris, Olivero, Boop & Sanford, 2003). A landmark study in 2003 addressed theproblem of fluid characteristics in ...

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

We report the case of a 76-year-old man who presented with slowly progressive antegrade amnesia. His medical history was remarkable for normal-pressure hydrocephalus successfully treated by a ventriculoperitoneal shunt 9 years earlier. The neurologic examination was unremarkable, but antegrade amnesia was confirmed by neuropsychological evaluation. The MR images showed a 2.5-cm suprasellar cyst displacing the lamina terminalis posteriorly, displacing the genu of the corpus callosum superiorly, and compressing the fornices bilaterally. The topography of the cyst was felt to be consistent with the clinical presentation, and the cyst was decompressed surgically. Intraoperatively, a second collection of fluid was found behind the lamina terminalis after its fenestration. The fluid was evacuated, and a ventricular shunt catheter was placed in the third ventricle.. The postoperative period was marked by sudden alteration in the patients mental status. A brain CT scan was obtained. In addition to the ...
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. ...

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.

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.. ...

Hacettepe Üniversitesi Tıp Fakültesi Nöroloji Anabilim Dalı, ANKARA Dementia is a condition resulting in significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. Many diseases can cause the dementia syndrome. Alzheimer disease (AD) and cerebrovascular disease (vascular dementia) are the two most common causes, and some cases of dementia involve both of these disorders. Some potentially reversible conditions, such as hypothyroidism, normal pressure hydrocephalus or vitamin B12 deficiency, are often known to cause dementia. AD is clinically characterized by progressive cognitive decline associated with impairment in activities of daily living and progresisive behavioural disturbances throughout the disease. Of all cases of dementia, 50-80 % were cases of AD. Patients with symptoms of dementia should be thoroughly evaluated before they become inappropriately labeled AD. This article discusses differential diagnosis ...

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 ...
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed. An EVD is a flexible plastic catheter placed by a neurosurgeon or neurointensivist and managed by intensive care unit (ICU) physicians and nurses. The purpose of external ventricular drainage is to divert fluid from the ventricles of the brain and allow for monitoring of intracranial pressure. An EVD must be placed in a center with full neurosurgical capabilities, because immediate neurosurgical intervention can be needed if a complication of EVD placement, such as bleeding, is encountered. EVDs are a short-term solution to hydrocephalus, and if the underlying hydrocephalus does not eventually resolve, it may be necessary to convert the EVD to a cerebral shunt, which is a fully internalized, long-term treatment for ...
Doppler ultrasound was used to measure blood flow velocity in the anterior cerebral artery of six premature infants with posthaemorrhagic hydrocephalus, before and after intermittent cerebrospinal fluid (CSF) drainage, on 23 occasions. There was a significant increase in mean blood flow velocity after the drainage procedures (+5.6 cm/s, 95% confidence interval +2.9 to +8.3 cm/s), which was accompanied by a decrease in velocity waveform pulsatility. CSF pressure also fell significantly. In patients with posthaemorrhagic hydrocephalus, intermittent CSF drainage was associated with acute changes in cerebral haemodynamics.. ...

PY - 1987/10. Y1 - 1987/10. N2 - Click-evoked auditory brain stem responses (ABRs) were measured using a Beyer DT48 circumaural earphone and an Etymotic ER-3A insert earphone in a group of normal-hearing subjects. Comparisons were made between time waveforms and amplitude spectra for the two transducers. ABR waveforms, latencies, and thresholds were compared for the two transducers. Click-evoked ABR and behavioral thresholds were comparable for the two earphones. In addition, absolute response-component latencies differed by an amount that was equivalent to the travel time introduced by the insert earphones sound-delivery tube. Inter-peak latency differences were virtually identical. These findings suggest that the insert earphone is a viable transducer for clinical ABR evaluations. Further, a temporal ...

A condition of increased pressure within the brain cavity, pseudotumor cerebri usually manifests itself as a bulging fontanelle in an otherwise happy and healthy infant, or as a sudden onset of strabismus in a child. It is also more properly known now as benign intracranial hypertension.. This condition may be associated with some medicines (the antibiotic tetracycline, used in infants years ago but no longer, was the most common drug-related cause), may arise as a complication of mastoiditis, or may just happen mysteriously. Because intracranial hypertension might not have a benign cause, if you should notice these symptoms immediate consultation with your doctor is of course in order. ...
