Active clinical trials for "Hydrocephalus"

Patients with hydrocephalus are usually treated with cerebrospinal fluid (CFS) shunt to deal with excess cerebrospinal fluid in the brain. However, it is difficult to distinguish whether ventricular enlargement is due to hydrocephalus or other causes, such as brain injury and compensatory brain atrophy after surgery. Therefore, it is important to predict whether shunting will help patients. For this reason, clinicians must be cautious when treating patients with shunt therapy. Important assessments of the level of consciousness and continuous lumbar tap test are currently clinically common predictors before making decisions about CFS shunt therapy. However, for patients with serious disturbance of consciousness, it is difficult to predict the prognosis of surgery by observing the improvement of symptoms after lumbar tap test, which brings difficulties to the majority of clinical workers, and also easy to bring serious psychological and economic burden to patients. In clinical practice, clinicians still lack a stable and objective method to predict postoperative outcomes for these patients. In this clinical study, when participants performed the cerebrospinal fluid tap test to evaluate whether or not cerebrospinal fluid shunt was performed, various predictors that may be associated with CSF shunt outcomes before and after cerebrospinal fluid tap test were collected, including imaging data, EEG characteristics and changes in cerebrospinal fluid pressure. In addition, the researchers will collect the improvement of consciousness disturbance in patients with hydrocephalus before and after cerebrospinal fluid shunt, in order to explore the correlation between preoperative imaging data, EEG characteristics, the results of cerebrospinal fluid tap test and the improvement of consciousness disorders. A scheme of consciousness assessment based on the results of imaging, EEG and tap test results afte CSF tap test was proposed.

This study aims to provide class 1 evidence supporting or refuting the existence of normal pressure hydrocephalus.

Aqueduct's Smart External Drain (SED) will be compared to the current gold standard for temporary CSF management in a hospital setting. Evaluate the number of subjects requiring to be switched to a standard of care EVD Evaluate subject transport while on the SED Evaluate SED system control from initiation of SED through discharge of external drain system

The investigators will quantify inflammatory biomarkers in cerebrospinal fluid (CSF) and serum of children with hydrocephalus who are undergoing ventriculoperitoneal shunt placement under isoflurane anesthesia.

This randomized, double-blinded, cross-over study aim to evaluate the effects of shunt treatment in idiopathic normal pressure hydrocephalus (iNPH) by measuring cerebral ventricular volume and clinical symptoms at different shunt opening pressures. Further, proteins in the cerebrospinal fluid (CSF) will be compared before and after shunt surgery.

To evaluate the performance characteristics of the Smart External Drain (SED) compared with standard EVD drains in the hospital setting, specifically: Number, type and duration of staff interactions. Regulating and controlling ICP and CSF drainage. Maintaining system control with patient movement.

Normal Pressure Hydrocephalus (NPH) is a clinical condition that induces cognitive deterioration that can be reverted, at least in part, by introducing ventricular-peritoneal diversion controlled by a miniaturized valve system. Mechanisms involved in such an improvement of cognitive function after liquor diversion are unknown. Oxysterols are a family of cholesterol-related compounds having diverse biological functions. Among others, they are involved in cholesterol homeostasis in the brain and are detectable in liquor, potentially impacting neurodegeneration. NPH is an ideal clinical model to study oxysterol distribution in liquor before and after ventricular-peritoneal diversion.

The goal of our study is to verify the effectiveness of the shunt and to identify the most sensitive criteria to select patients for surgery. The study is designed to assess improvement in walking and balance (gait), urinary function and memory after shunting. In addition, the study aims to identify the most accurate and sensitive tools to measure improvement for our patients.

The purpose of this study is to study whether infants with triventricular hydrocephalus (TVH) have a better long-term outcome at 5 years when they are treated with a new procedure, endoscopic third ventriculostomy (ETV), than infants treated with the more traditional treatment, insertion of a cerebrospinal fluid (CSF) shunt.

This study evaluates the performance of a device for non-invasively assessing cerebrospinal fluid (CSF) shunt flow. Patients with an existing implanted shunt will wear the device to acquire longitudinal data.
