The drainage provided by a shunt can alleviate or prevent these problems in patients with hydrocephalus or related diseases. Shunts come in a variety of forms, but most of them consist of a valve housing connected to a catheter, the lower end of which is usually placed in the peritoneal cavity. The main differences between shunts are usually in ...
This treatment does not place a foreign body into the patient so there is a much lower risk of infection as compared to a shunt procedure. Along with not implanting a device, this procedure avoids mechanical issues like disconnection, over or underdrainage, and valve dysfunction. [3]
There are various categories of medical shunts and there are two main categories of shunt used in the treatment of chronic increased intracranial pressure due to cerebrospinal fluid (CSF), they are cerebral shunts and lumbar shunts (extracranial shunts). Below is a list of the various types of the above two categories of shunts:
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.
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.
The ophthalmic artery (OA), a unique vessel with intracranial and extracranial segments, is used as a pressure sensor and as a natural pair of scales for absolute ICP value in mmHg or mmH2O measurement. Blood flow in the intracranial OA segment is affected by intracranial pressure, while flow in the extracranial (intraorbital) OA segment is ...
Occasionally, shunts are placed to drain excess cerebrospinal fluid from the brain. [citation needed] The goals of treatment include: closure of open skin defects to prevent infection and desiccation of brain tissue; removal of nonfunctional extracranial cerebral tissue with water-tight closure of the dura
Treatment may be necessary when symptomatic. [2] A variety of procedures may be used to decompress (remove pressure from) the cyst. Surgical placement of a cerebral shunt: [25] An internal shunt drains into the subdural compartment. [26] A cystoperitoneal shunt drains to the peritoneal cavity.
