Programmable cerebrospinal fluid (CSF) shunt valves are crucial for treating hydrocephalus, especially in NPH and pediatric cases. This study offers a guide to identifying and interpreting settings for these important programmable shunt valves.

Area of Science:

  • Neurosurgery
  • Medical Devices
  • Radiology

Background:

  • Programmable cerebrospinal fluid (CSF) shunt valves are essential in managing hydrocephalus.
  • Their use is particularly significant in Normal Pressure Hydrocephalus (NPH) and complex pediatric hydrocephalus cases.

Purpose of the Study:

  • To create a unified reference for identifying programmable shunt valves.
  • To provide clear guidelines for interpreting the settings of programmable shunt valves.

Main Methods:

  • Collaboration with four major programmable shunt manufacturers.
  • Collection of radiographic images and interpretation legends for each valve.
  • Discussion of Magnetic Resonance (MR) imaging compatibility for the valves.
