Ventricular shunt. Coloured X-ray showing a ventricular shunt (upper centre) implanted in the head of a 72-year-old man with hydrocephalus. 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. A ventricular shunt is a neurosurgical implant that allows the drainage of excess CSF from the affected ventricle.
