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. The proSA is a gravity activated valve whose resistance varies iwht its orientation to the earth’s gravitational field.

The Polaris is also less susceptible to inadvertent setting changes by household magnets. Nevertheless, product literature advises that patients with either a Sophy or Polaris valve have their setting checked immediately after MR imaging. The Miethke proGAV Programmable Shunt System (Aesculap, Tuttlingen, Germany) is a posture-dependent valve.

Shunt and Valve Settings | Neupsy Key. Neupsykey.com Shunt Settings. Michael J. Fritsch. First, ventriculoperitoneal (VP) shunt placement is the treatment of choice for patients with NPH. 1 Alternatives, such as endoscopic third ventriculostomy, have not been proven to match the clinical results achieved by shunt placement. 2001-11-01 Confirmation of the programmable valve setting with a skull x-ray film perpendicular to the valve is important in shunt-dependent patients and serves as a reference for symptoms with equivocal objective changes. Noninvasive methods to demonstrate an obstruction include an evaluation of the scalp for a subcutaneous fluid collection.

The teletransducer could guide us on how to properly adjust the valves.

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).

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 In hydrocephalus, a shunt is used to connect a compartment filled with cerebrospinal fluid (CSF) and a cavity within the body where the drained fluid can be absorbed. In neurosurgical practice, the ventriculoperitoneal (VP) shunt is used most often. Usually a shunt includes a valve, which controls drainage throughout the shunt.

A tool to streamline the process of adjusting shunt valve settings to accommodate individual needs for CSF drainage. While the settings for these valves in each patient must currently be determined empirically over a number of weeks, Shuntcheck will be helpful in measuring changes in CSF flow due to changes in the valve setting. Programmable shunts allow for the setting of a specific pressure above which fluid drains through a valve. This is sometimes adjusted in one direction or another for VP shunt patients who experience headaches, lightheadedness or other symptoms related to the pressure when their evaluation is negative for obstruction, infection etc. Programmable shunt valve settings can be altered by exposure to magnetic fields.

Reports from Europe have stated that some patients have benefited from having this shunt.

Programmable shunt valve settings can be altered by exposure to magnetic fields. Indeed, specialized magnets are used by physicians to adjust the settings on these valves. 2010-11-11 Inoue T, Kuzu Y, Ogasawara K, Ogawa A.
