However, programmable shunt valves are adjusted with an external magnet. Changes in the valve-pressure setting have occurred after exposure of programmable valves to an MRI magnetic field [ 21 ]. Before performing MRI on a patient with a programmable shunt, the radiologist must confirm that the shunt is resistant to reprogramming at the magnetic field strength of the scanner. 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. A programmable CSF shunt valve was assessed for magnetic field interactions, heating (transmit-receive body radio-frequency coil; whole-body averaged specific absorption rate, 2.1 W/kg SUMMARY: The programmable CSF shunt valve has become an important tool in hydrocephalus treat-ment, particularly in the NPH population and in pediatric patients with complex hydrocephalus.
2015). Codman Hakim 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. Syringoperitoneal shunting with a programmable shunt valve was safe and effective for clinical control of syringomyelia associated with extensive SAA. Long-term follow-up is mandatory to monitor for shunt dysfunction and mechanical trouble.

The programmable valve showed minor magnetic field interactions and heating was not excessive (+0.8 degrees C). The function of the programmable valve was not the shunt valve had migrated into diploe of parietal bone. Further, shunt series X-rays (Fig. 4) sh owed a disconnection. Shunt Malfu nction.
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.
Changes in the valve-pressure setting have occurred after exposure of programmable valves to an MRI magnetic field [ 21 ].

The nonprogrammable valve group had no valve malfunctions. The overall VP shunt revision rate in the nonprogrammable valve group was 20.2%. They exhibit a high rate of shunt survival across all age groups, with valve survival rates as high as 90% at 12 months [1] and above 80% after 2 years. [2] For infants, a group known to have a higher rate of complications than adult patients, favorable survival rates were also observed. [2]
