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).
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.
However, the shunt jammed too often, causing pain and blindness, risking brain damage and requiring emergency surgery. [1] Till, a neurosurgeon at London's Great Ormond Street Hospital for children, determined that debris accumulated in the hydrocephalic ventricles could clog the slits in the Holter valves, especially with patients such as Theo ...
The EVD is a foreign body inserted into the brain, and as such it represents a potential portal for serious infection. Historically, the rate of infections associated with EVDs has been very high, ranging from 5% to > 20%. [10] [11] Infections associated with EVDs can progress to become a severe form of brain infection known as ventriculitis.
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 ...

A Peritoneovenous shunt: (also called Denver shunt) [2] is a shunt which drains peritoneal fluid from the peritoneum into veins, usually the internal jugular vein or the superior vena cava. It is sometimes used in patients with refractory ascites. It is a long tube with a non-return valve running subcutaneously from the peritoneum to the ...
One of the common causes of subdural hygroma is a sudden decrease in pressure as a result of placing a ventricular shunt. This can lead to leakage of CSF into the subdural space especially in cases with moderate to severe brain atrophy. In these cases the symptoms such as mild fever, headache, drowsiness and confusion can be seen, which are ...
