Computed tomography based assessment of programmable shunt valve settings [PDF]

Brain and Spine, 2021
Introduction: Programmable shunt valve settings can sometimes be difficult to assess using classic read-out tools, warranting a skull X-ray. Research question: Can we use available head computed tomography (CT) scans to determine the valve settings, in ...

Evaluating the additive properties of differential pressure valves in a novel benchtop shunt model [PDF]

Fluids and Barriers of the CNS
Objective Cerebrospinal fluid (CSF) over-drainage is an unintended sequela of using a shunt valve to treat hydrocephalus, and a second valve may be added in series to better control drainage.

Category-2 shunt valve marketed as MRI-Conditional malfunction following routine 3 T magnetic resonance imaging

Interdisciplinary Neurosurgery, 2021
Background: CSF diversion techniques have been in use for decades, with the first plastic-based ventricular shunt designs originating in the 1960 s. The first generation of valves, termed fixed differential pressure (DP) valves, have a fixed flow rate ...
