The location of the shunt is determined by the neurosurgeon based on the type and location of the blockage causing hydrocephalus. All brain ventricles are candidates for shunting. The catheter is most commonly placed in the abdomen but other locations include the heart and lungs. [10] Shunts can often be named after the route used by the ...
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.

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). When catheter drainage is permanent, it is usually referred to as a shunt.
The EVD is leveled to a common reference point that corresponds to the skull base, usually the tragus or external auditory meatus.The EVD is set to drain into a closed, graduated burette at a height corresponding to a particular pressure level, as prescribed by a healthcare professional, usually a neurosurgeon or neurointensivist.
Neurosurgeons can use ShuntCheck flow results along with other diagnostic tests to assess shunt function and malfunction. [1] Hydrocephalus is a condition in which cerebrospinal fluid (CSF) accumulates in the brain, potentially leading to brain damage and death. It is corrected by a shunt which drains excess CSF from the brain to the abdomen.
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.
Bonaduce described for TMZ that during the upcoming operation, the surgeons will place a “shunt in my head” and a “drainboard” to remove the liquid from his brain.
Shunt surgery is one of the most common procedures in pediatric neurosurgery. Significant advances in shunt technology and surgical approaches have been made over the years. However, the lifetime risk for a revision surgery of a ventriculoperitoneal shunt in pediatric patients can reach up to 80%. [9] Shunt failure rates are also high.
