The catheter components of a shunt are made from Si- lastic(DowCorning,Midland,Michigan),aformofrubbertub- ing resistant to breakdown in the body. As with previous ventricular shunts, this valve is surgically implanted over the skull near the burr hole for the catheter. When reading a skull film with this valve in place, you should give the current pressure setting of the valve. This will be a value between 30 mm H2O and 200 mm H2O. Dr Daniel J Bell and Dr Jan Frank Gerstenmaier et al. Programmable cerebrospinal shunts are a type of ventriculoperitoneal shunt that can be set to different CSF pressure settings. They are of particular value in normal pressure hydrocephalus and in pediatric patients.

J Neurol Neurosurg Psychiatry 84:813–817. The images are analyzed by the engine, and the system categorizes the type of shunt(s) (e.g., ventriculoperitoneal or ventriculopleural), number of valves, valve type (e.g., Codman), number of catheters, and then classifies the shunt catheter as either intact, discontinuous, or kinked, determines the programmable shunt valve setting(s), and identifies the location of tip of the catheter(s). 2021-04-17 · The layout of this chapter is broken down by the manufacturer of the shunt, listed in alphabetical order. Images of each shunt valve on standard radiography are provided. Images showing the various shunt settings are also available for reference. With regard to MRI, the product insert for the CODMAN HAKIM Programmable Valve states: "Note: Remember to verify valve pressure setting after an MRI." DELTA SHUNT ASSEMBLY The Delta Shunt Assembly (Medtronic Neurosurgery, Goleta, CA) combines the Delta valve with an integral, open-end, radiopaque peritoneal catheter. CSF shunt valves have either fixed or programmable (adjustable) pres-sure settings.

References: Reproduced with permission from Aesculap, Inc. One-third of all shunts fail within 1 year of placement, and in children 4.5% per year thereafter. Manifestations of shunt failure are variable so patients with shunts frequently undergo radiographic evaluation. 2016-04-01 2004-10-11 The images are analyzed by the engine, and the system categorizes the type of shunt(s) (e.g., ventriculoperitoneal or ventriculopleural), number of valves, valve type (e.g., Codman), number of catheters, and then classifies the shunt catheter as either intact, discontinuous, or kinked, determines the programmable shunt valve setting(s), and identifies the location of tip of the catheter(s). Manage hydrocephalus with a shunt intended to maintain its performance level setting under MRI exposure when scanned in accordance with the MR conditions in the labeling.

Issues of MR imaging compatibility for each valve are also discussed. The valve setting is interpreted on the basis of the position of the notch and orientation marker. Current product literature states that patients with an implanted Codman Hakim Programmable Valve can safely undergo MR imaging under the following conditions: 1) static magnetic field of #3T 2) spatial gradient of #720 G/cm and 3) limited radio-frequency Programmable cerebrospinal shunts are a type of ventriculoperitoneal shunt that can be set to different CSF pressure settings. They are of particular value in normal pressure hydrocephalus and in pediatric patients.

Assessment of Left Ventricular Function and Hemodynamics

The Codman Hakim valve is a ventricular shunt valve which can be programmed to open at various CSF fluid pressure. As with previous ventricular shunts, this valve is surgically implanted over the skull near the burr hole for the catheter. Codman SiphonGuard an add-on valve for the therapy of overdrainage (slit-ventricle syndrome). It is intended to prevent uncontrolled loss of CSF from the brain via the shunt system.
