A cerebral shunt is a device permanently implanted inside the head and body to drain excess fluid away from the brain. They are commonly used to treat hydrocephalus , the swelling of the brain due to excess buildup of cerebrospinal fluid (CSF).
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.

Ventriculostomy is a neurosurgical procedure that involves creating a hole (stoma) within a cerebral ventricle for drainage. It is most commonly performed on those with hydrocephalus. [1] It is done by surgically penetrating the skull, dura mater, and brain such that the ventricular system ventricle of the brain is accessed. When catheter ...
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
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the medical specialty that focuses on the surgical treatment or rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nervous system, and cerebrovascular system.

Hans Chiari (September 4, 1851 − 1916) was an Austrian pathologist who described in 1891 a brain malformation that is characterized by abnormalities in the region where the brain and spinal cord meet, and it causes part of the cerebellum to protrude through the foramen magnum (bottom of the skull) into the spinal canal. This was to be called ...
