A programmable CSF shunt valve was assessed for magnetic field interactions, heating (transmit-receive body radio-frequency coil; whole-body averaged specific absorption rate, 2.1 W/kg SUMMARY: The programmable CSF shunt valve has become an important tool in hydrocephalus treat-ment, 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.

Reproduced with permission from Aesculap, Inc. 2015-03-13 · 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. There have been specific instances of these cases: A boy playing with toy magnets altered the valve settings on his shunt, 38 a man with a programmable shunt attempted suicide by using an electromagnet, 39 an iPad 2 altered the setting on the valve of a 4-month-old girl, 37 and the shunt setting of a 5-year-old boy was changed by a household electric appliance. 40 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).

Syringoperitoneal shunting with a programmable shunt valve was safe and effective for clinical control of syringomyelia associated with extensive SAA. Long-term follow-up is mandatory to monitor for shunt dysfunction and mechanical trouble. Venous stenting costs significantly less per 100 procedures than does CSF shunting, due largely to the high cost of treating shunt infections and the need for repeated shunt revisions.

As with previous ventricular shunts, this valve is surgically implanted over the skull near the burr hole for the catheter. Strata Adjustable Pressure 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 Shunt valve designs include slit, miter, diaphragm, and spring-loaded ball-in-cone. Shunt valves can be set at a fixed opening and closing pres-sure or can be externally pro-grammed using magnetic tools.16 This is useful for the patient whose Signs and symptoms of hydrocephalus in older children and This video discusses the design of the Medtronic Contoured Valve and the CSF pathway through the valve from the ventricular or proximal catheter to the perit Shunt valve designs include slit, miter, diaphragm, and spring-loaded ball-in-cone.
