At the proximal end, the shunt valve can become blocked due to the buildup of excess protein in the CSF. The extra protein will collect at the point of drainage and slowly clog the valve. The shunt can also become blocked at the distal end if the shunt is pulled out of the abdominal cavity (in the case of VP shunts), or from similar protein ...
A tool to streamline the process of adjusting shunt valve settings to accommodate individual needs for CSF drainage. While the settings for these valves in each patient must currently be determined empirically over a number of weeks, Shuntcheck will be helpful in measuring changes in CSF flow due to changes in the valve setting.

Carlos, with the collaboration of his father, has recently developed a programmable and adjustable (through the skin) valve which may prevent ventricular collapse when the pressure of the CSF is too low. [citation needed] Today, the valve is marketed under the name Codman Hakim valve, acquired by Integra LifeSciences in 2017. [5] [6] [7]
The subarachnoid space is a spongy tissue-filled cavity that surrounds the brain and spinal cord, where cerebrospinal fluid (CSF) is contained. The shunt is placed under the skin, continues around the oblique muscles on one side of the body, and terminates at the peritoneal cavity, a cavity in the abdomen area of the body. Once in place the ...
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.
For suspected cases of NPH, CSF shunting is the first-line treatment. The most common type used to treat NPH is ventriculoperitoneal (VP) shunts, which drain CSF fluid to the peritoneal cavity. Adjustable valves allow fine-tuning of CSF drainage. NPH symptoms reportedly improve in 70–90% of patients with CSF shunt.
Cerebrospinal fluid diversion is a procedure that is used to drain fluid from the brain and spinal cord. A shunt is placed in a ventricle of the brain and threaded under the skin to another part of the body, usually the abdomen. It is used to treat hydrocephalus and idiopathic intracranial hypertension.
Cardiac shunts may be described as right-to-left, left-to-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic.; Cerebral shunt: In cases of hydrocephalus and other conditions that cause chronic increased intracranial pressure, a one-way valve is used to drain excess cerebrospinal fluid from the brain and carry it to other parts of the body.
