Shunt valve designs include slit, miter, diaphragm, and spring-loaded ball-in-cone. Shunt valves can be set at a fixed opening and closing pressure or can be externally programmed using magnetic tools. 16 This is useful for the patient whose CSF drainage needs will change over time.

1 A valve is often inserted into the catheter pathway to keep CSF flowing away from the brain and to moderate the pressure or flow rate. 1 Some valves are 2010-02-12 · c) Radiographic appearance of the Sophysa Polaris SPV valve (set to Position 5, 200mm H2O).

In consideration of the test results, this new programmable CSF shunt valve is not adversely affected by the 3-T MRI environment and is acceptable for a patient undergoing MRI at 3 T or less when specific guidelines are followed, including verifying the valve setting according to manufacturer recommendations immediately after the MRI procedure.

This can be quite significant, as infection may have further implications and detrimental effects on the individual including abscess formation or shunt occlusion. If infection occurs, the shunt will generally need to be revised (Rinker et al. 2015).
