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.

Usually a shunt includes a valve, which controls drainage throughout the shunt. Delwel EJ, de Jong DA, Dammers R, Kurt E, van den Brink W, Dirven CM (2013) A randomised trial of high and low pressure level settings on an adjustable ventriculoperitoneal shunt valve for idiopathic normal pressure hydrocephalus: results of the Dutch evaluation programme Strata shunt (DEPSS) trial. J Neurol Neurosurg Psychiatry 84:813–817. The images are analyzed by the engine, and the system categorizes the type of shunt(s) (e.g., ventriculoperitoneal or ventriculopleural), number of valves, valve type (e.g., Codman), number of catheters, and then classifies the shunt catheter as either intact, discontinuous, or kinked, determines the programmable shunt valve setting(s), and identifies the location of tip of the catheter(s). 2021-04-17 · The layout of this chapter is broken down by the manufacturer of the shunt, listed in alphabetical order.

of this study is to provide a single reference for the identification of programmable shunt valves and the. interpretation of programmable shunt valve settings.

Aetiologies of shunt failure include obstruction, valve failure, infection and excessive or insufficient drainage [19]. In pediatric shunt procedures, it has been noted that 14% of shunt failure occur within the first month of shunt placement [20,21]. 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. Newer valves such as the Polaris (Sophysa) and Pro-GAV (Aesculap) are resistant to reprogramming even at a 3-T magnetic field.

Shunt design (multiple shunt pieces have more risk of disconnecting Most common location of breakage is in neck, followed by the scalp either proximal or distal to valve or connecting devices Patients with broken shunts may present with

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 MRI-induced programmable valve setting alteration. The patient with a percutaneously programmable cerebrospinal fluid shunt, presented acutely obtunded after undergoing MRI at 1.5T the previous day. The pressure settings were not checked following MRI. 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 ].

As with previous ventricular shunts, this valve is surgically implanted over the skull near the burr hole for the catheter. When reading a skull film with this valve in place, you should give the current pressure setting of the valve.

Gravitational Shunt Benefits. 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.

A, Setting code for the Sophysa Sophy SM8 valve.Operating pressure (millimeters of water) for each position is depicted in the lower left hand corner of each panel. 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..
