Following the bidirectional Glenn shunt, failure of the procedure can be broadly categorized as failure of procedure, cardiac dysfunction related to surgery, or cardiac dysfunction leading to death before further surgical intervention. [8] Retrospective reviews demonstrate failure of the procedure in 6.5% of patients.
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).
Glenn procedure is a palliative surgical procedure performed for patients with Tricuspid atresia.It is also part of the surgical treatment path for hypoplastic left heart syndrome and hypoplastic right heart syndrome.
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.

The revision of a shunt means to replace or make adjustments to all or part of the shunt, this also means that the location of the shunt may be changed therefore changing the category or type of shunt a patient has. For some patients with shunts, a revision or multiple revisions to the shunt may be required. This can be something minor, such as ...
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]
The shunt failure rate is also relatively high (of the 40,000 surgeries performed annually to treat hydrocephalus, only 30% are a person's first surgery) and people not uncommonly have multiple shunt revisions within their lifetimes. [48]
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.
