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 ...
It is a long tube with a one-way valve running subcutaneously from the peritoneum to the internal jugular vein in the neck, which allows ascitic fluid to pass directly into the systemic circulation. Various models exist, among which the LeVeen shunt and the Denver shunt. [2] Possible complications include: Infection; Superior vena caval thrombosis
Shunt surgery, usually performed by neurosurgeons, involves the creation of a conduit by which CSF can be drained into another body cavity. The initial procedure is usually a lumboperitoneal (LP) shunt, which connects the subarachnoid space in the lumbar spine with the peritoneal cavity. [24]
Techniques such as angioplasty, stenting, clot retrieval, embolization, and diagnostic angiography are endovascular procedures. [44] A common procedure performed in neurosurgery is the placement of ventriculo-peritoneal shunt (VP shunt). In pediatric practice this is often implemented in cases of congenital hydrocephalus. The most common ...
The CSF tap test, sometimes lumbar tap test or Miller Fisher Test, is a medical test that is used to decide whether shunting of cerebrospinal fluid (CSF) would be helpful in a patient with suspected normal pressure hydrocephalus (NPH).
A shunt system can also be placed in the lumbar space of the spine. This allows the excess fluid to be redirected to the peritoneal cavity ( lumbar-peritoneal shunt ). [ 51 ] Another treatment for obstructive hydrocephalus is an endoscopic third ventriculostomy (ETV).
Ventriculostomy is a neurosurgical procedure that involves creating a hole (stoma) within a cerebral ventricle for drainage. It is most commonly performed on those with hydrocephalus . [ 1 ] It is done by surgically penetrating the skull , dura mater, and brain such that the ventricular system ventricle of the brain is accessed.
