In the pediatric population, the shunt failure rate two years after implantation has been estimated to be as high as 50%. [23] Those patients with advanced age, prolonged hospital stay, GCS score of less than 13, extra-ventricular drains in situ, or excision of brain tumors are more likely to have early shunt malfunction.

The Wade-Dahl-Till (WDT) valve is a cerebral shunt developed in 1962 by hydraulic engineer Stanley Wade, author Roald Dahl, and neurosurgeon Kenneth Till. [1] [2] In 1960, Dahl's son Theo developed hydrocephalus after being struck by a taxicab. A standard Holter shunt was installed to drain excess fluid from his brain.
Gait symptoms improve in ≥ 85% patients. Cognitive symptoms improve in up to 80% of patients when surgery is performed early in the disease course. Urgency and incontinence improve in up to 80% of patients, but only in ≤ 50–60% of patients with shunt implanted late in disease course.
A shunt has risk of infection and failure for which subsequent surgery is needed. Complications of ETV include hemorrhage (the most severe being due to basilar artery rupture), injury to neural structures (e.g. hypothalamus , pituitary gland or fornix of the brain ), and late sudden deterioration.

Additional epilepsy surgery following hemispherectomy is rare (4.5%), [7] but may be recommended if there is a residual connection between the two hemispheres that is causing frequent seizures. Mortality rates are low and estimated to be <1% to 2.2%. [6] [7] Most patients do not experience changes in cognition, but some individuals may be at ...

Each of the types of shunts listed above can be composed of a tube or catheter and various types of valves, although they can just be composed of the tubing or catheter. Below is a list of valves that are used in lumbar–peritoneal shunts (LP shunts) and Cerebral shunts (for a more detailed list of the types of valves see type of valves): Delta
