These are placed to relieve pressure in the brain usually in hydrocephalus.The shunt will help prevent brain damage from abnormal fluid build-up in the ventricles which otherwise would cause increased swelling of the babies head and severe brain damage.The shunt can become blocked or infected but with proper care will save babies life and brain function.
The primary complication short term and long term is infection in the jugular vein. With proper care this can be minimized. The main long term risk is a hematoma, and there is an outside risj of stroke. The baby will probably need additional surgery.
