In this review of the neurosurgery literature, the reported rate of mechanical malfunction ranged from 8% to 64%. The use of programmable valves has increased but remains of unproven benefit even in randomized trials. Infection was the second most common complication, with the rate ranging from 3% to 12% of shunt operations. A meta-analysis that included 17 randomized controlled trials of perioperative antibiotic prophylaxis demonstrated a decrease in shunt infection by half (OR 0.51, 95% CI 0.36-0.73). Similarly, use of detailed protocols including perioperative antibiotics, skin preparation, and limitation of OR personnel and operative time, among other steps, were shown in uncontrolled studies to decrease shunt infection by more than half.. Other adverse events included intraabdominal complications, with a reported incidence of 1% to 24%, intracerebral hemorrhage, reported to occur in 4% of cases, and perioperative epilepsy, with a reported association with shunt procedures ranging from 20% ...
OBJECTIVE: Infection after cerebrospinal fluid (CSF) shunts or ventriculostomies is a common complication associated with significant morbidity and mortality. Polymerase chain reaction (PCR) is a powerful molecular technique that allows rapid and precise amplification of bacterial deoxyribonucleic acid (DNA) and has proven a powerful tool in the detection of a wide variety of clinically important infectious diseases. We analyzed specimens of CSF derived from ventriculoperitoneal shunts or external ventricular drains by using both conventional cultures and PCR and report herein our preliminary results. METHODS: We selected 86 CSF samples from adult patients who underwent either shunt tap or routine surveillance cultures of their ventriculostomy. These specimens were chosen from a larger group of 300 specimens that were routinely collected (many serially) in our clinical practice. They were chosen because clinical suspicion of infection was increased because of either patient signs and symptoms ...

The final results for the infants at 1 year of age whose mothers participated in the MOMS trial are consistent with the previously published results.1,4 This report presents a more comprehensive look at the primary outcome and at preexisting risk factors that may alter the benefit of prenatal surgery and be associated with the reduction in the need for shunting.. In this analysis, we have shown that the degree of hydrocephalus at the time of screening (19-25 weeks) has a significant impact on the effect of prenatal surgery. This is consistent with previously published studies prior to MOMS, which suggested that shunting is rarely avoided in patients with moderately to severely enlarged ventricles at the time of prenatal screening.4 The finding also has implications with regard to the timing of prenatal intervention and the counseling of prospective candidates. We know that the ventricles in a fetus with spina bifida tend to enlarge during gestation.2 By extension, it is likely that fetuses ...

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 syndrome characterized by ventricular dilatation due to disturbed cerebrospinal fluid (CSF) circulation, accompanied by gait disturbance, dementia and/or urinary incontinence without causative disorders. With the aging of Japanese society, the number of patients is increasing, requiring diagnostic and therapeutic guidelines for the improvement of the patients quality of life and social care. Under such conditions, this project was made as the prospective study of iNPH on Neurological Improvement (SINPHONI ). This study aims 1) to establish methods for non-invasive diagnosis of iNPH, and 2) to demonstrate therapeutic outcome of shunting operation by Codman Hakim programmable valve (CHPV). In this protocol, the evaluation of validity on MRI, tap test, CT cisternography, and CBF (3D-SSP) will be done in the diagnosis, and manual of initial setting pressure in CHPV for prevention of overdrainage problems will be estimated by modified Rankin scale ...

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 ...

Results 39 patients (24 male, 15 female) met criteria. Mean [SD] age at the time of shunt insertion was 84 years (+/− 3.22) (range 80-94). No patients developed immediate CSF infection or sub-dural collection, or extended length of stay due to surgical or ...
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 ...
The original contribution by Isik et al. [5], remarking on the utility of serial CSF fluid removal in elderly patients with NPH, is surely important. In their report, they present the results of the benefit of serial CSF removal in 43 patients with NPH. They illustrate the results of walking trials and detailed cognitive tests that they performed pre- and post-LP. However, there are some points to be clarified for a better understanding of this article and related issues. First, in the study by Isik et al. [5], the authors define their aim as investigating the outcome of serial removal of CSF in this patient subgroup. However, in our opinion, this might not be properly investigated via this study method. Remarkably, clinical evaluations were made after 24 hours of CSF removal, but no clinical data on the long-term follow-up after CSF removal were included in the study. Otherwise, the authors emphasize their method of evaluating the criteria for the deterioration of gait (which was defined as a , ...

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 ...
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
