CSF Shunt Valve X-Ray Identification Guide
Visual reference for identifying cerebrospinal fluid (CSF) shunt valves used in the treatment of hydrocephalus by their X-ray appearance. Browse programmable and non-programmable valve models from major manufacturers including Miethke, Medtronic, Codman, Sophysa, and Integra. Each valve includes links to official vendor documentation, instructions for use, MRI safety information, and pressure setting guides.
Programmable Valves
Medtronic Strata NSC
The Strata NSC is a non-symbol-coded variant of the Strata family. On X-ray, it presents the same cylindrical titanium housing as other Strata valves but without the programmable adjustment mechanism. The valve body is identifiable by its compact, smooth-edged radiopaque profile.
Codman Hakim Programmable Valve
The Codman Hakim Programmable Valve offers 18 pressure settings from 30 to 200 mmH2O. On X-ray, the distinctive circular adjustment dial is visible within the titanium housing. The valve has a characteristic round profile with identifiable markings indicating the current pressure setting.
Codman CERTAS™ Plus Programmable Valve
The CERTAS Plus offers 8 programmable pressure settings with an enhanced antisiphon device. On X-ray, the circular adjustment mechanism with numbered settings is visible within the radiopaque housing. The valve body has a compact disc-like profile with identifiable internal configuration.
Non-Programmable Valves
Medtronic PS Medical Pressure Differential
The Medtronic PS Medical Pressure Differential valve operates at a fixed differential pressure. On X-ray, the cylindrical titanium housing with internal differential mechanism is visible. The valve has a compact, uniform radiopaque appearance without external adjustment features.
Codman Fixed Pressure Valve
The Codman Fixed Pressure valve provides consistent differential pressure without adjustability. On X-ray, the cylindrical titanium body with internal ball-and-spring mechanism is visible. The valve has a simple, compact radiopaque profile similar to other fixed-pressure designs.
Spitz Holter
The Spitz-Holter valve, introduced in 1956, was one of the earliest CSF shunt valves used in hydrocephalus treatment. On X-ray, its distinctive early-generation design is recognizable by the radiopaque silicone and metal components.
