Many of the complications require immediate shunt revision (the replacement or reprogramming of the already existing shunt). The common symptoms often resemble a new onset of hydrocephalus, such as headaches, nausea, vomiting, double vision, and an alteration of consciousness. This can result in damage to an individual's short-term memory. [10]
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
Baby recovering from shunt surgery Ventriculoperitoneal shunt placement in child with hydrocephalus Hydrocephalus is treated through surgery by creating a way for the excess fluid to drain away. An external ventricular drain (EVD), also known as an extraventricular drain or ventriculostomy, provides relief in the short term. [ 38 ]
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 ...
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.
Moreover, the procedure may lead to significant complications, including blindness in 1–2%. [5] The procedure is therefore recommended mainly in those who have limited headache symptoms but significant papilledema or threatened vision, and those who have undergone unsuccessful treatment with a shunt or have a contraindication for shunt ...
Any variation from this formula can lead to an ineffective, yet patent shunt system, despite a low-pressure setting. Care should be taken with EVD therapy, as mismanagement of the EVD can lead to long-term permanent complications and brain injury. [citation needed]
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
