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 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. AJNR Am J Neuroradiol 31:1343 A programmable CSF shunt valve was assessed for magnetic field interactions, heating (transmit-receive body radio-frequency coil; whole-body averaged specific The CODMAN HAKIM Programmable Valve (CSF shunt valve, Codman, a Johnson & Johnson Company, Raynham, MA) includes a valve mechanism that incorporates a flat 316L stainless steel spring in which the calibration is accomplished by a combination between a pillar and a micro-adjustable telescoping fulcrum.

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. Venous stenting costs significantly less per 100 procedures than does CSF shunting, due largely to the high cost of treating shunt infections and the need for repeated shunt revisions. AJNR Am J Neuroradiol . Unlike fixed shunt valves, programmable devices allow the operator to alter the amount of CSF drainage without the need for shunt revision or valve replacement.

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. 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.

2006. 27: 661-5. 9. Shellock FG, Wilson 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 v The CODMAN HAKIM Programmable Valve (CSF shunt valve, Codman, a Johnson & Johnson Company, Raynham, MA) includes a valve mechanism that incorporates a flat 316L stainless steel spring in which the calibration is accomplished by a combination between a pillar and a micro-adjustable telescoping fulcrum. This video covers the 3 types of Medtronic valves used for the treatment of hydrocephalus: the Contoured Valve, part of the CSF Flow Control valve family; th According to the AJNR 2010 article by Lollis et al, the Codman Hakim valve is set at 60 mm water (which is the same as the pre MRI setting).

We have never noticed any malfunction in correlation to MRI scans up to 1.5 Tesla yet. There is possibility to identify the opening pressure type of the valve in X-ray (low, medium, high pressure types of valves). 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.

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.
