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.

METHODS: A total of 104 patients undergoing ventriculoperitoneal shunt placement were analyzed for shunt position, revision surgery and outcome. The results for patients operated on using intraoperative biplanar fluoroscopic assessment of catheter location (X-ray group, n = 57) were compared with a control group operated without intraoperative radiography (control, n = 47). Finally, the shunt end was dragged into the right atrium smoothly. Post procedure chest X-ray confirmed the accurate position of the distal catheter of the shunt in right atrium (Fig. 3). Following endovascular re-positioning, the shunt function was optimal.

The external portion of the catheter is connected to a valve that regulates the flow of CSF based on a preset The basic components of a CSF shunt include a proximal catheter, reservoir, valve, and distal catheter. The proximal catheter tip is ideally positioned in the frontal horn of either lateral ventricle, anterior to the foramen of Monro away from the choroid plexus [ 3] (Fig. 1).

Indications Departmental protocols will vary but the overall goal is to image the shunt in its entirety to assess 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 ]. Before performing MRI on a patient with a programmable shunt, the radiologist must confirm that the shunt is resistant to reprogramming at the The setting of the valve can be determined by comparing the position of the radiopaque marker on the valve cam to the fixed position of the radiopaque right-hand side indicator on the base plate of the valve. Comparing the patient radiographs to the diagram on the programming unit panel will indicate the valve setting.

Coloured X-ray of the head of a 38-year-old patient with hydrocephalus, showing the position of a ventricular shunt (dark lines) and its external valve (round, centre right). Hydrocephalus, or water on the brain, is a medical condition in which there is an abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles (cavities) of the brain.
