The cerebrospinal fluid (CSF) bathes the brain and spinal cord. Most of the CSF is in the ventricles of the brain, which are large cavities within the brain which produce and reabsorb the CSF.
IndicationsIn hydrocephalus, the ventricles of the brain become enlarged with cerebrospinal fluid. This condition causes the brain tissue to become compressed against the skull, thus causing serious neurological problems. Shunting, called ventriculoperitoneal shunting, is necessary to drain the excess fluid and relieve the pressure in the brain. This should be done as soon as hydrocephalus is recognized to give the child the best possible neurological outlook.
IncisionThis procedure is performed in the operating room under general anesthesia. A flap is cut in the scalp and a small hole is drilled in the skull.
ProcedureA small catheter is passed into a ventricle of the brain. A pump is attached to the catheter to keep the fluid away from the brain. Another catheter is attached to the pump and tunneled under the skin, behind the ear, down the neck and chest and into the peritoneal cavity (abdominal cavity). The CSF is absorbed in the peritoneal cavity.
AftercareVentriculoperitoneal shunting is often crucial for preventing serious brain damage in children with hydrocephalus. Common problems associated with VP shunts include shunt malfunction and shunt infection. Shunts are generally left in place for many years if they function without problems.

The time it takes to recover from a Ventriculoperitoneal Shunt operation varies with each patient. It also depends on the success of the operation and how the patient responded to it.

The primary treatment for DWM and associated hydrocephalus is the placement of a ventriculoperitoneal (VP) shunt

It depends. Most Ventriculoperitoneal ( VP for short) shunts may be implanted for life for the treatment of hydrocephalus ( excessive cerebral spinal fluid, or CSF, build up in the brain ). The type of shunt and the health problem it is treating will ultimately determine the length of implantation.
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
Basic voltage regulators are classified as either SERIES or SHUNT, depending on the location or position of the regulating element(s) in relation to the circuit load resistance.
