A peritoneovenous shunt is a shunt which drains peritoneal fluid from the peritoneum into a large vein, usually the internal jugular vein. It is sometimes used in patients with refractory ascites . [ 1 ]
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).
The lumbar–peritoneal shunt is inserted between two of the lumbar vertebrae of the spine into the subarachnoid space.The subarachnoid space is a spongy tissue-filled cavity that surrounds the brain and spinal cord, where cerebrospinal fluid (CSF) is contained.
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 ...
Most shunts drain the fluid into the peritoneal cavity (ventriculoperitoneal shunt), but alternative sites include the right atrium (ventriculoatrial shunt), pleural cavity (ventriculopleural shunt), and gallbladder
Hydrocephalus is usually treated through the insertion of a shunt, such as a ventriculo-peritoneal shunt, which diverts fluid to another part of the body. [31] [32] Idiopathic intracranial hypertension is a condition of unknown cause characterized by a rise in CSF pressure.
External drains go from inside the body to outside the body and can be seen, while internal drains are completely inside the body. An example of an internal drain is a ventriculo-peritoneal shunt, which is a tube that connects ventricles of the brain to the peritoneal cavity. This helps remove extra cerebrospinal fluid from the 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.
