  2. Cerebral shunt - Wikipedia

    en.wikipedia.org/wiki/Cerebral_shunt

    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).

  3. Normal pressure hydrocephalus - Wikipedia

    en.wikipedia.org/wiki/Normal_pressure_hydrocephalus

    VP shunt is less likely to be recommended in those who have severe dementia at time of NPH diagnosis, regardless of findings found on MRI or CT. [10] [28] Gait symptoms improve in ≥ 85% patients. Cognitive symptoms improve in up to 80% of patients when surgery is performed early in the disease course.

  4. Subdural hygroma - Wikipedia

    en.wikipedia.org/wiki/Subdural_hygroma

    Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]

  5. Hydrocephalus - Wikipedia

    en.wikipedia.org/wiki/Hydrocephalus

    Shunt obstruction is the most common cause of shunt failure. [68] The shunt can be obstructed at the catheter or the valve itself. Cases of shunt obstruction would present with similar symptoms to untreated hydrocephalus (headaches, nausea, lethargy, etc.). [68] It can be caused by tissue, bacteria, or kinking of the catheter.

  6. Low pressure hydrocephalus - Wikipedia

    en.wikipedia.org/wiki/Low_pressure_hydrocephalus

    The pressure in the brain does not get high enough to allow the cerebrospinal fluid to drain in a shunt system, therefore the shunt is open, but malfunctioning in LPH. In cases of LPH, chronic infarcts can also develop along the corona radiata in response to the tension in the brain as the ventricles increase in size.

  7. External ventricular drain - Wikipedia

    en.wikipedia.org/wiki/External_ventricular_drain

    The EVD is leveled to a common reference point that corresponds to the skull base, usually the tragus or external auditory meatus.The EVD is set to drain into a closed, graduated burette at a height corresponding to a particular pressure level, as prescribed by a healthcare professional, usually a neurosurgeon or neurointensivist.

  8. Shunt (medical) - Wikipedia

    en.wikipedia.org/wiki/Shunt_(medical)

    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 ...

    The treatment of choice in NPH is ventriculoperitoneal shunt surgery (VPS). This treatment needs a VP shunt, which is a catheter with a valve aiming at implementing a one-way outflow of the excessive amount of CSF from the ventricles. It is obligatory to have patency control because of some possible complications such as infections and obstruction.
