Hydrocephalus is the buildup of fluid in the cavities (ventricles) deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain. Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column.
The most common treatment for hydrocephalus is surgery to put in a shunt. The shunt is used to drain extra CSF from ventricles in your child's brain to some other part in their body. There, the fluid is absorbed. The goal of putting in a shunt is to drain the CSF that your child's body makes each day (about a pint).
