In reality, treatment of hydrocephalus is little influenced by the type of valve used. A disposable endoscope is used to open a small membrane at the floor of the third ventricle. This creates a new pathway for the CSF to flow by passing the blockage to normal CSF circulation. Typically, when a shunt is placed, extra tubing is coiled at the distal end so a shunt does not need to be lengthened as a child grows. Usually if a shunt stops working, symptoms of hydrocephalus will recur and revision of the shunt will be necessary.
Shunts can stop working because of infection, formation of scar tissue or shunt breakage.
Once a child has recovered from the surgery, there are usually no activity restrictions. They may participate in any sporting activities. A medical card with information about the shunt type and valve is available for patients to carry. A variety of written materials are available for review in the Mayo Clinic Patient Health and Education Center. Health education specialists are also available to help families locate pertinent resources.
