shunt valves may use portable game machines, the permanent magnets in these machines may alter the shunt valve programmed settings or permanently damage the device. This study investigated the risk of unintentional valve adjustment associated with the use of game machines in patients with programma-ble CSF shunt valves. Rick Abbott, M.D. Andrew Kobets, M.D. Judiah G. Burns, M.D. X-ray images of hydrocephalic shunt valves. Fixed Differental Pressure Valves Aesculap Fixed Differential Pressure Valve Codman Fixed Differential Pressure Valves Medtronic Fixed Differential Pressure Valves Anti-Siphon Valves, Gravity Activated Valves Aesculap Gravity Activated Valves Chhabra Gravity Activated Valve Codman Gravity Thus, the valve settings can be changed during a routine office visit avoiding any surgery. Reports from Europe have stated that some patients have benefited from having this shunt. Clearly, siphoning occurs with this system so it is unclear to what degree the feature of valve adjustment will be of benefit. The setting of the CERTAS Plus Programmable Valve is changed through the use of an externally applied magnetic field.

They are of particular value in normal pressure hydrocephalus and in pediatric patients. The 2010 AJNR article by Lollis et al. 1 provides radiographic features ( with reference images ) of the settings of five common valves (Codman Hakim Programmable Valve, Medtronic Strata, Sophysa Sophy SM8, Sophysa Polaris SPV, and Aesculap Miethke proGAV). Changes in the valve-pressure setting have occurred after exposure of programmable valves to an MRI magnetic field . Before performing MRI on a patient with a programmable shunt, the radiologist must confirm that the shunt is resistant to reprogramming at the magnetic field strength of the scanner. Newer valves such as the Polaris (Sophysa) and Pro-GAV (Aesculap) are resistant to reprogramming even at a 3-T magnetic field. Ventriculoperitoneal (VP) shunts are a device used to shunt cerebrospinal fluid in the treatment of hydrocephalus.

2017-11-15 ‘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. Presented as a 2019-06-07 The programmable CSF shunt valve has become an important tool in hydrocephalus treatment, particularly in the NPH population and in pediatric patients with complex hydrocephalus. The purpose of this study is to provide a single reference for the identification of programmable shunt valves and the interpretation of programmable shunt valve settings. In response to these findings, the ventricular shunt valve setting was lowered to 30 mm H 2 O to reduce resistance to CSF drainage. The cervical tourniquet was reapplied to increase ICP so that the ventricles would shrink. Within hours, the diplopia had disappeared and the DMS had largely resolved. Programmable shunt valve settings can be altered by exposure to magnetic fields.

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.
