ShuntCheck can be used to detect CSF flow in asymptomatic hydrocephalus patients and can be used to detect no-flow in symptomatic patients with shunt obstruction. Secondarily, the ShuntCheck test will yield the clearest results when patients are tested sitting up (or alternatively while supine)
Isolated uni or bilateral mild cerebral ventriculomegaly represents the most frequent “minor” cerebral anomalies discovered by antenatal echography. There are not French data making it possible to specify the incidence and the prevalence of this pathology and international data of the prevalence are very heterogeneous, going, according to the published series, of 1.48 to 22 per 1000 births. The prognostic of ventriculomegaly remains dubious : the studies have small populations, are for the majority retrospectives with a short and often vague follow-up. The announced rate of after-effects varies between 0 and 48 %. The objective of this study is to evaluate the neuropsychological development until the 5 years age of the children for whom a prenatally diagnosis of mild isolated ventriculomegaly was carried (absence of another cerebral or extra-cerebral anomaly in imagery and a negative aetiology). This prospective cohort will be compared with children for whom no neurological anomaly was prenatally detected. The children diagnosed for an mild isolated cerebral ventriculomegaly will be identified by the investigators among medical files of the Centers of Prenatal Diagnosis (CPDPN) of the UH of Angers and the UH of Nantes. The patient inclusion will be done at the 2 years age after parental agreement, with a follow-up at 5 years. The control children will be included under the same conditions after having ensured of the normality of the echographies of 22 and 30 gestational weeks. The follow-up of these 2 cohorts will be based on the 2 years obligatory paediatric examination, and on the network “Naitre ensemble” set up in the Pays de la Loire Loire. In addition to the clinical routine examinations, standardized neuropsychological examinations will be done (Brunet Lezine Revised score at 2 years, NEPSY at 5 years and ASQ at 2 and 5 years). This study will allow to compare the neuropsychological development at school age of the children diagnosed for a foetal mild, apparently isolated, cerebral ventriculomegaly from children not presenting any foetal anomaly, to evaluate the incidence of the mild isolated ventriculomegaly, to identify the predictive factors of the neuropsychological anomalies in the children diagnosed for ventriculomegaly and to compare (in the children diagnosed for ventriculomegaly), the neuropsychological development at the school age of the children having a ventricular atrium between 10 and 12 mm with those having a ventricular atrium between 12,1 and 15 mm. This study will allow to define the neuropsychological morbidity of the foetal mild isolated cerebral ventriculomegaly and will allow to define the best clinical and educational follow up of these children and their family.
External ventricular catheters are used for intracranial pressure monitoring and temporary cerebrospinal fluid (CSF) drainage in neurosurgery. The incidence of ventriculostomy-related cerebrospinal fluid infections had been quoted as between 2.2% to 10.4% in the more recent literature. Previous prospective studies in the investigators' unit have shown that the use of dual antibiotics prophylaxis in patients with external ventricular drain was associated with decreased incidence of CSF infection but was complicated with opportunistic extracranial infections. The current practice is to cover with prophylactic dual antibiotics unless guided by microbiology results for all patients with external ventricular drain. In recent years, cerebrospinal fluid shunt catheters impregnated with antimicrobial agents have been available. Experimental studies have shown that they provide protection against staphylococcal aureus and coagulase-negative staphylococci strains for between 42 days and 56 days. Theoretically, they provide the antibiotic prophylaxis locally without the associated complications of systemic antibiotics. It is hypothesized that the use of antibiotic-impregnated catheters instead of systemic antibiotic prophylaxis will not increase the rate of cerebrospinal fluid infection, will decrease the rate of opportunistic/nosocomial infections and improves the overall outcome in these patients; that would convert into a reduction in treatment cost of these patients.
The purpose of this Registry is to compare shunt/catheter-related infection rates among various shunt systems when used according to hospital standard of care to treat hydrocephalus.
Isolated mild fetal ventriculomegaly is a common finding in fetal ultrasound examinations. When the ventricular diameter is more than 15 mm it is usually considered as severe and connected to other malformations. Most of these children will be severely affected later in life. Less than 10 mm ventricular width considered as normal. The current medical knowledge can not answer questions regarding future development of children who were diagnosed to suffer from mild (10-14.9 mm) brain ventriculomegaly during the pregnancy. We would like to assess the development and neurological status of all children who were diagnosed as "mild ventriculomegaly" during the pregnancy in the last 6 years and to prospectively follow up all the children who will be diagnosed from the beginning of the study on for 6 years. We hypothesized that the course of their development is different than of other children.
The overall aim of the registry is to develop a longitudinal, observational database that is focused on adult patients with Normal Pressure Hydrocephalus (NPH) that can be used as a source of clinical information for individual surgeons, as well as a national data repository for scientific inquiry and publications.
This study evaluates the efficacy of shunt operation for idiopathic normal pressure hydrocephalus, and determines the diagnostic value of noninvasive procedures commonly practiced in the clinic.
The purpose of this study is to determine the agreement rate between the CODMAN Valve Position Verification (VPV) adjustment outcome (reprogramming) and X-ray verification in order to support an alternative to X-ray confirmation with respect to the valve adjustment process.
Hydrocephalus (secondary or idiopathic) is a condition characterized by dilatation of the lateral and third ventricles, and often associated with increased intracranial pressure (ICP). We hypothesize that either the ventricle dilatation or the increased ICP may cause disturbances in the hypothalamic-pituitary axis, resulting in different degrees of hypopituitarism. The goal of this study is to determine the prevalence of hypopituitarism in adult patients with hydrocephalus.
