The most likely patients to show improvement are those who show only gait deviation, mild or no incontinence, and mild dementia. The risk of adverse events related to shunt placement is 11%, including shunt failure, infections such as ventriculitis, shunt obstruction, over- or under-drainage, and development of a subdural hematoma.

The drainage provided by a shunt can alleviate or prevent these problems in patients with hydrocephalus or related diseases. Shunts come in a variety of forms, but most of them consist of a valve housing connected to a catheter, the lower end of which is usually placed in the peritoneal cavity. The main differences between shunts are usually in ...
Hydrocephalus is typically treated by the surgical placement of a shunt system. [1] A procedure called a third ventriculostomy is an option in some people. [1] Complications from shunts may include overdrainage, underdrainage, mechanical failure, infection, or obstruction. [1] This may require replacement. [1]
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 drainage is temporary, it is commonly referred to as an external ventricular drain (EVD).
A major advantage of performing an endoscopic third ventriculostomy over placement of a cerebrospinal fluid shunt is the absence of an implanted foreign body. A shunt has risk of infection and failure for which subsequent surgery is needed.
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
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.
ShuntCheck is a non-invasive diagnostic medical device which detects flow in the cerebral shunts of hydrocephalus patients. Neurosurgeons can use ShuntCheck flow results along with other diagnostic tests to assess shunt function and malfunction.
