Active clinical trials for "Hydrocephalus"

Endoscopic Third Ventriculostomy for Adults with Hydrocephalus: Creating a Prognostic Model for Success - A Retrospective Multicenter Study Background: Endoscopic third ventriculostomy (ETV) is becoming an increasingly widespread treatment for hydrocephalus, but most of the research is based on paediatric populations. The ETV Success Score (ETVSS) was developed in 2009 to predict the outcome of ETV in children. There is no similar tool for predicting outcome in adults. Objective: The purpose of this study is to create a prognostic model to predict the success of ETV for adult patients with hydrocephalus Methods: The study will adhere to the TRIPOD reporting guidelines and will be conducted as a retrospective chart review of all patients ≥18 years old treated with ETV at the participating centres between Jan 1st, 2010 and Dec 31st, 2018. Data collection is conducted locally in REDCap. Univariate analyses will be used to identify several strong predictors to be included in a multivariate logistic regression model. The model will be validated using K-fold cross validation. Discrimination will be assesses using AUROC and calibration with calibration belt plots. Expected outcomes: The ability to predict who will benefit from an ETV will allow better primary patient selection both for ETV and shunting. This would reduce additional second procedures due to primary treatment failure. A success score specific for adults could also be used as a communication tool to provide better information and guidance to patients.

Normal pressure hydrocephalus (NPH) can cause a type of dementia. However, this type of dementia is the only one that is reversible. To treat this dementia it is necessary to evacuate the accumulation of CSF from the brain to another body cavity using a device called a shunt. But the implantation of this shunt is only effective when the cause of the pathology is an alteration of the normal circulation of the CSF. To diagnose these patients, morphological MRI and lumbar puncture are standard approaches used but remain perfectible in diagnostic terms. The main objective is to build a new model of the interaction of intracranial pressures and fluids in order to obtain a new parameter allowing to obtain information on the cerebral biomechanics.

This study uses frequency domain near-infrared spectroscopy coupled with diffuse correlation spectroscopy (FDNIRS-DCS) technology for monitoring cerebral blood flow (CBF) and cerebral oxygen metabolism (CMRO2) at the bedside for newborns with germinal matrix-intraventricular hemorrhage (GM-IVH) and/or post-hemorrhagic hydrocephalus (PHH) in comparison to newborns with hydrocephalus of a different etiology (VC) and healthy controls (HC). We hypothesize that baseline cerebral metabolic dysfunction is a better biomarker for GM-IVH and PHH severity and response to PHH treatment. This is a Boston Children's Hospital (BCH)-institutional review board(IRB) approved, multi-site study that includes collaboration with Brigham and Women's Hospital (BWH) and Beth Israel Deaconess Medical Center (BIDMC). Pei-Yi Lin receives funding from The National Institute of Health (NIH) to support the study and is the overall principal Investigator (PI) overseeing the study.

Patient with childhood hydrocephalus (HC) tend to present late in Low medium income countries (LMICs). This project will study the barriers leading to patients' and health system delay in patients with childhood HC. This will be done via a quantitative and qualitative study analysis. The data will be collected prospectively.

Neonatal postinfectious hydrocephalus (PIH) is a major public health problem in East Africa.The standard treatment has long been placement of a ventriculoperitoneal shunt (VPS) but these devices require life-long maintenance and nearly all fail multiple times. Endoscopic Third Ventriculostomy (ETV) with Choroid Plexus Cauterization (ETV/CPC) is an alternate treatment to give patients a shunt-free life. In this study, the investigators aim to optimize the metrics of evaluation as quantitative prognostic indicators of treatment response and long term outcomes.

The purpose of this study is to assess the diagnostic accuracy of ShuntCheck compared with radionuclide shunt patency testing (SPS) to detect CSF shunt flow of NPH patients with suspected shunt obstruction.

The aim of this study is to collect systematically and proactively data regarding the performance of Neuro-Patch, like complications and handling, under daily clinical practice when used as intended by the manufacturer

This study evaluates the performance of a non-invasive thermal measurement device for assessing CSF shunt flow. Patients with an existing implanted shunt and symptoms of shunt malfunction will be evaluated with the study device.

The purpose of this project is to assess the utility of a new magnetic resonance technique called magnetic resonance elastography (MRE) in the non-invasive diagnosis of normal pressure hydrocephalus. The investigators hypothesize that MRE produces a unique imaging signature for hydrocephalus that distinguishes the disease from the normal (non-hydrocephalic) but atrophied brain, a distinction not possible with conventional MR imaging studies that are presently available.

20 patients who are diagnosed with NPH receive a set of 5 wearable gyroscopes (IMUs, ZurichMove sensors) for a period of 3 days for measurement and characterization of their walking in an ambulatory setting. At a follow-up 2 weeks to 6 months after CSF diversion surgery, the examination is repeated and improvement is measured. The data will be compared with a healthy group of 20 age- and gender-matched individuals as well a a group of 20 young individuals.
