Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
For example, it may be required for a patient with a lumbar–peritoneal shunt, if multiple revisions are required or overdrainage is occurring, to have it replaced with a ventriculo–peritoneal shunt (VP shunt). Shunt revisions are required due to the following complications: Over drainage; Under drainage; Infection; Blockage or obstruction
Which can result in a variety of neurological symptoms, such as pseudotumor cerebri, chronic fatigue syndrome, different types of headaches, visual disturbances, pulsatile tinnitus and various neurodegenerative diseases.

Cerebral shunts that drain fluid to the peritoneal cavity (located in the upper abdomen) are called ventriculoperitoneal (VP) shunts. Lumbar-peritoneal shunt (a.k.a. lumboperitoneal, LP): In cases of chronic increased intracranial pressure such as idiopathic intracranial hypertension and hydrocephalus, a tube or shunt with or without a one-way ...
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).
Cerebral edema is excess accumulation of fluid in the intracellular or extracellular spaces of the brain. [1] This typically causes impaired nerve function, increased pressure within the skull, and can eventually lead to direct compression of brain tissue and blood vessels. [1]
The shunt also has a valve which serves to maintain one-way flow of the CSF and regulates the flow rate. The end with the catheter is placed in the third ventricle to drain the excess CSF and the other end is placed in the peritoneal cavity or atrium of the heart (making it a ventriculoperitoneal or ventriculoatrial shunt, respectively). The ...
When catheter drainage is permanent, it is usually referred to as a shunt. There are many catheter-based ventricular shunts that are named for where they terminate, for example, a ventriculoperitoneal shunt terminates in the peritoneal cavity, a ventriculoatrial shunt terminates within the atrium of the heart, etc.
