The study hypothesis is that an ultrasonic flow sensor can accurately measure flow in hydrocephalic shunts.
The ultrasonic sensor will measure cerebrospinal fluid drainage in hydrocephalus patients with external ventriculostomies and extra-ventricular drainage systems. The sensor measurements will be compared with the volume of fluid collected by the drainage bag.
After a 24-hour measurement period, the doctor will change the drainage bag position to simulate the patient sitting up and leaning back, to see if this temporarily stops flow through the drainage line.
This data will show whether the sensor accurately measures typical drainage flows seen in hydrocephalus patients. This research will help develop an implantable flow monitor for pediatric hydrocephalus patients.

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 ...
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...
The purpose of this study is to determine whether endoscopic choroid plexus coagulation is safe in adult patients with communicating hydrocephalus and risk factors for complications from t...
This study aims to provide class 1 evidence supporting or refuting the existence of normal pressure hydrocephalus.
The purpose of this study is to test and compare the efficacy of Endoscopic Third Ventriculostomy with shunting of Cerebrospinal fluid (CSF)for treatment for patients of Normal pressure Hy...
Hydrocephalus patients experience symptoms related to hydrocephalus in an age-dependent manner. However, prevalence estimates of hydrocephalus symptoms in young and middle-aged (YMA) adult patients ar...
/Objective: Hydrocephalus is a common neurosurgical disorder that can lead to significant disability or death if not promptly identified and treated. Data on the burden of hydrocephalus in low-income ...
Hydrocephalus can be progressive or spontaneously arrested. In arrested hydrocephalus, the balance between production and absorption of the cerebrospinal fluid is restored. Patients are mostly asym...
Low-pressure hydrocephalus (LPH) and negative-pressure hydrocephalus (NegPH), secondary to traumatic brain injury, cerebral hemorrhage, tumor resection and central nervous system (CNS) infection in ad...
Hydrocephalus, unless treated, is one of the terminal manifestations of intracranial metastatic disease. Single lesions causing obstructive hydrocephalus are amenable to surgical resection, but in the...
Excessive accumulation of cerebrospinal fluid within the cranium which may be associated with dilation of cerebral ventricles, INTRACRANIAL HYPERTENSION; HEADACHE; lethargy; URINARY INCONTINENCE; and ATAXIA (and in infants macrocephaly). This condition may be caused by obstruction of cerebrospinal fluid pathways due to neurologic abnormalities, INTRACRANIAL HEMORRHAGES; CENTRAL NERVOUS SYSTEM INFECTIONS; BRAIN NEOPLASMS; CRANIOCEREBRAL TRAUMA; and other conditions. Impaired resorption of cerebrospinal fluid from the arachnoid villi results in a communicating form of hydrocephalus. Hydrocephalus ex-vacuo refers to ventricular dilation that occurs as a result of brain substance loss from CEREBRAL INFARCTION and other conditions.
A form of compensated hydrocephalus characterized clinically by a slowly progressive gait disorder (see GAIT DISORDERS, NEUROLOGIC), progressive intellectual decline, and URINARY INCONTINENCE. Spinal fluid pressure tends to be in the high normal range. This condition may result from processes which interfere with the absorption of CSF including SUBARACHNOID HEMORRHAGE, chronic MENINGITIS, and other conditions.

1,4:3,6-Dianhydro D-glucitol. Chemically inert osmotic diuretic used mainly to treat hydrocephalus; also used in glaucoma.
Surgical creation of a communication between a cerebral ventricle and the peritoneum by means of a plastic tube to permit drainage of cerebrospinal fluid for relief of hydrocephalus. (From Dorland, 28th ed)
A congenital abnormality in which the occipitofrontal circumference is greater than two standard deviations above the mean for a given age. It is associated with HYDROCEPHALUS; SUBDURAL EFFUSION; ARACHNOID CYSTS; or is part of a genetic condition (e.g., ALEXANDER DISEASE; SOTOS SYNDROME).
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
