Shunt valve settings

The authors initiated the study after having issues with a programmable shunt in a four-month-old girl patient who received a shunt with a magnetically programmable valve to regulate the flow of CSF. After the girl’s mother used an iPad 2 while holding her daughter, the doctors found that the patient’s shunt valve settings had been changed. ‘Virtual Off’ setting (Performance Setting 8) Other 7 discrete Performance Settings cover a broad range of operating pressures to optimize the shunt performance to meet the needs of the hydrocephalus patient The valve is designed to withstand unintended pressure setting changes due to external magnetic inﬂ uences, including MRI up to 3 Tesla1 Hydrocephalus, the imbalance between production and absorption of Cerebrospinal Fluid (CSF), is known as unpredictable in its evolution. Sophysa set a significant milestone with a major advance in the treatment of hydrocephalus, with the introduction in 1985 of the first adjustable valve in the world and has never stopped innovating since. The Polaris valve and proGAV were immune to unintentional reprogramming by the DS. However, the settings of the CHPV and Strata valves were randomly altered by the DS. Patients with an implanted shunt valve should be made aware of the risks posed by the magnetic fields associated with portable game machines and commonly used home electronics. PMID: The magnetic fields generated by airport security doors should not affect the pressure setting of your valve.

This will be a value between 30 mm H2O and 200 mm H2O. Codman Certas Valve. The Certas Valve is the first generation of programmable differential pressure Certas valves by Codman and has been discontinued due to problems during MRI scanning and accidental reprogramming. Please, check current information of the manufacturer, as radiological verification of shunt adjustment can be recommended. A, Radiographic appearance of the Codman Hakim Programmable Valve (set to 90 mm H 2O). B, Setting code for the Codman Hakim Programmable Valve.

When it comes to the details of shunt valve settings, there is a wide range of options to choose from: Shall we implant valves regulated by CSF flow or rather use valves regulated by intracranial pressure? Shall we use a single differential pressure valve or is a combination with an anti-siphon device (ASD) preferable? With a programmable VP shunt, your neurosurgeon can adjust the shunt’s pressure settings, even after it has been placed. In general, a higher pressure setting means less CSF is being drained. A lower pressure setting means more CSF is being drained. The settings are different for each manufacturer. Codman Certas Valve.

The Strata® Valve from Medtronic is part of a Ventricular shunt system used to treat the symptoms of hydrocephalus.. It is an adjustable flow-control valve. The Strata valve has 5 settings or P/L, ranging from 0.5 to 2.5. Each performance level corresponds to a range of opening pressures and flow rates; generally, a lower performance level corresponds to a 2021-02-02 This video covers the 3 types of Medtronic valves used for the treatment of hydrocephalus: the Contoured Valve, part of the CSF Flow Control valve family; th ‘Virtual Off’ setting (Performance Setting 8) Other 7 discrete Performance Settings cover a broad range of operating pressures to optimize the shunt performance to meet the needs of the hydrocephalus patient The valve is designed to withstand unintended pressure setting changes due to external magnetic inﬂ uences, including MRI up to 3 Tesla1 Hydrocephalus Shunt Valve Assessment.
