1 , Yoshinaga Kajimoto M.D., D.M.Sc. 1 and Kohji Nagao M.D. 1 The paper by Lollis et al provides a reference for the identification of programmable shunt valves and the interpretation of programmable shunt valve settings. There are a few types depending on the manufacturer. 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.

The verification of shunt adjustment (so-called opening pressure) and also the primary identification of the implanted valve type can be a Problem in daily practice: Shunt pass is not always at hand and documents from external hospitals can be missing. Usually, a simple lateral skull X-ray helps to identify the type of valve and it’s adjustment.

Ventriculoperitoneal (VP) shunts are a device used to shunt cerebrospinal fluid in the treatment of hydrocephalus. As the name suggests, a catheter is placed with its tip in the ventricle. The external portion of the catheter is connected to a valve that regulates the flow of CSF based on a preset pressure.

SUMMARY: The programmable CSF shunt valve has become an important tool in hydrocephalus treatment, particularly in the NPH population and in pediatric patients with complex hydrocephalus. The purpose of this study is to provide a single reference for the identification of programmable shunt valves and the interpretation of programmable shunt valve settings. Four major manufacturers of shunt valve agreed to participate: Aesculap (Tuttlingen, Germany), Codman/Johnson&Johnson(Raynham,Massachusetts),Medtronic (Minneapolis,Minnesota),andSophysa(Orsay,France).Themanu-facturers provided photographs and plain radiographs of program-mable shunt valves in current production as well as the appropriate Materials for this programmable shunt valve include titanium alloy (TiAl6V4) for the housing, rotor, and spring; a 2-mm sapphire ball (sapphire Al203), and small magnets (NdFeB) 1 mm in diameter and 1.30 mm in length, integrated in the valve rotor (Fig 1).

AJNR Am J Neuroradi ol 30:635 Headphones are even more ubiquitous, and they contain an electromagnet for sound projection that sits on the head very close to the shunt valve. This study is the first to look at the magnetic field emissions of headphones and their effect on reprogrammable shunt valves to ascertain whether headphones are safe for patients with these shunts to wear. Reading Skull Films for Shunt Valve Settings 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.
