Objectives: The aim of this study was to investigate the relationship between the pressure setting of the ventriculoperitoneal (VP) shunt valve and a magnetic resonance (MR)-based estimate of intracranial pressure (ICP) in children with shunt-treated hydrocephalus without clinical signs of shunt malfunction. Materials and methods: Institutional review board approval was obtained before the

The CODMAN CERTAS Plus Programmable Valve is an implantable device that pressure and drainage of CSF for the management of hydrocephalus. should confirm the valve setting after a magnetic resonance imaging (MRI) procedure.

Thus, a check-up of the valve setting after MRI is not necessary. Shunt Settings Michael J. Fritsch First, ventriculoperitoneal (VP) shunt placement is the treatment of choice for patients with NPH.1 Alternatives, such as endoscopic third ventriculostomy, have not been proven to match the clinical results achieved by shunt placement. Ventriculoatrial (VA) shunts may be used as an alternative, but they should be used only in patients… Fig 4. A, Complete Aesculap Miethke proGAV assembly.

Your shunt valve setting can be changed by your physician using a programming device, or it can be You have an MRI for any reason (CT scans have no effect on the shunt).

Researchers at Brown University examined three magnetically programmable shunt valves to see if the magnetic field emissions of headphones can cause unintentional changes in shunt valve settings. ‘From the Department of Radiology’, Division of Pediatric Radiology, Loma Linda University Medical Center and Children’s Hospital, 1 1234 Anderson St. Loma Linda, CA 92354.

Applying a specific magnetic field to the adjustable valve mechanism will permit the cam to turn slightly, increasing or decreasing the tension on the spring, and changing the setting of the valve.

Programmable shunts allow for the setting of a specific pressure above which fluid drains through a valve. This is sometimes adjusted in one direction or another for VP shunt patients who experience headaches, lightheadedness or other symptoms related to the pressure when their evaluation is negative for obstruction, infection etc.
