Presented as a of a shunt system before and after implantation. A shunted The setting of the CODMAN CERTAS Plus Programmable Valve is changed through the use of an. Various types of shunt valve have been developed for the management of hydrocephalus. Among these, adjustable shunt valves are widely programmable shunt valve systems are implantable devices that provide constant (MRI) as the magnet can move the valve setting in either direction, of this study is to provide a single reference for the identification of programmable shunt valves and the.

CSF shunt valves have either fixed or programmable (adjustable) pres-sure settings. Fixed shunt valves, which are not programmable, have opening and closing pressures set by the manufacturer and are not adjust-able. They function as a pop-off valve and have fewer parts and are potentially associated with fewer complications. However, if the CSF

Programmable cerebrospinal shunts are a type of ventriculoperitoneal shunt that can be set to different CSF pressure settings. They are of particular value in normal pressure hydrocephalus and in pediatric patients. The 2010 AJNR article by Lollis et al. 1 provides radiographic features ( with reference images ) of the settings of five common valves (Codman Hakim Programmable Valve, Medtronic Strata, Sophysa Sophy SM8, Sophysa Polaris SPV, and Aesculap Miethke proGAV).

When the pressure setting is increased in a conventional adjustable valve system, resistance is increased for all positions, not just the upright position. This results in increased ICP in the lying position causing headaches, nausea and other symptoms. Differential Pressure Valve.

Aesculap has two valves which can be adjusted using a magnetic programmer.. The proGAV is a pressure differential valve that can have its opening pressure adjusted.

Lateral radiograph (a) with magnified view (inset) of the VP shunt valve (encircled). The pressure setting can be read on the radiograph, but not on the axial CT image (b). The magnetic components of the programmable shunt produce extensive susceptibility artifacts on MRI (c) failure is defined as a shunt complication requiring revision or replacement [19]. Aetiologies of shunt failure include obstruction, valve failure, infection and excessive or insufficient drainage [19].

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. A shunt is a completely inter- nalized system, as opposed to an external ventricular drain in which a ventricular catheter drains to a collection system at the bedside. The catheter components of a shunt are made from Si- lastic(DowCorning,Midland,Michigan),aformofrubbertub- ing resistant to breakdown in the body. As with previous ventricular shunts, this valve is surgically implanted over the skull near the burr hole for the catheter.

Manage hydrocephalus with a shunt intended to maintain its performance level setting under MRI exposure when scanned in accordance with the MR conditions in the labeling. Medtronic is conducting a voluntary recall of the StrataMR valve due to an issue that can occur post-implantation that can lead to the potential for under-drainage of cerebrospinal fluid.

Programmable shunt valve settings can be altered by exposure to magnetic fields.
