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).
Lumbar puncture (LP), also known as a spinal tap, is a medical procedure in which a needle is inserted into the spinal canal, most commonly to collect cerebrospinal fluid (CSF) for diagnostic testing.
Complications from the surgery can cause a loss of cerebrospinal fluid (CSF), which could cause severe headaches. This can be corrected by returning to the medical facility and having them perform a blood patch. In this procedure, a small amount of blood is taken from the arm and injected into the exact spinal tap location to stop the leaking ...
An epidural blood patch (EBP) is a surgical procedure that uses autologous blood, meaning the patient's own blood, in order to close one or many holes in the dura mater of the spinal cord, which occurred as a complication of a lumbar puncture or epidural placement. [1] [2] The punctured dura causes cerebrospinal fluid leak (CSF leak). [1]
Heme from red blood cells (RBC) that are in the cerebrospinal fluid because a blood vessel was damaged during the lumbar puncture (a "traumatic tap") has no time to be metabolized, and therefore no bilirubin is present. After the cerebrospinal fluid is obtained, a variety of its parameters can be checked, including the presence of xanthochromia.
The three main components in determining ICP is the blood circulation in the brain, cerebrospinal fluid (CSF), and the brain tissue itself. This relationship is dictated by the Monro-Kellie doctrine, which states that as the brain swells, intracranial pressure (ICP) rises and cerebral perfusion decreases.
Drainage system showing bloody CSF due to intracranial hemorrhage [ edit on Wikidata ] 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 ...
In addition, damage to small blood vessels during lumbar puncture (traumatic tap) can lead to an increased CSF glucose since the blood that enters the collected CSF sample contains higher levels of glucose. [4] CSF glucose levels do not generally exceed 16.7 mmol/L (300 mg/dL). [3]
