2004-03-01 Integra Omni-Shunt System. The Omni-Shunt System is a non-programmable differential pressure valve. 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). The purpose of this study was to provide a single reference containing radiographic depictions of the major programmable shunt valves in current use as well as information for accurate reporting of shunt valve settings. This will assist radiologists and other physicians in the complete assessment of skull radiographs in patients with shunts.

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 People implanted with magnetic externally programmable CSF shunt valves may have risk of experiencing an unintended change in their valve setting when exposed to magnets from implantable middle Fig. 8.1 Scanning Electron Microscopy of a shunt valve of diaphragm type, removed from a patient due to shunt malfunction. There is precipitation of crystals on the diaphragm, which with time deteriorates and interferes with the physical properties of the membrane and can block the gap between diaphragm and case (magnification ×100) Immune Response Investigation… They are later replaced by the more efficient ventricular-atrial shunt (9). The shunting device has a valve that opens at a determined pressure and thus permits drainage of cerebrospinal fluid from the ventricles of the brain to another body compartment. The two popular valve mechanisms used are the Holter valve and the Hakim valve (4).

The shunt valves were adjusted up or down one level, and the new settings were confirmed by both X-ray imaging and the manufacturers’ shunt tools. The valves were repositioned on the right side of the phantom, and the scanning and evaluation process were repeated. Table 2 Details of the imaging parameters used in Part II of the protocol
