Illustration depicting lumbar puncture (spinal tap) Spinal needles used in lumbar puncture Illustration depicting common positions for lumbar puncture procedure. The person is usually placed on their side (left more commonly than right). The patient bends the neck so the chin is close to the chest, hunches the back, and brings knees toward the ...
Quincke's puncture" is a somewhat outdated eponym for lumbar puncture, [4] [5] used for the examination of the cerebrospinal fluid in numerous diseases such as meningitis and multiple sclerosis. In 1893 he described what is now known as idiopathic intracranial hypertension, which he labeled "serous meningitis". [6]
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]
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 lumbar puncture can give the symptom of a post-dural-puncture headache. A cerebrospinal fluid leak can be either cranial or spinal, and these are two different disorders. [5] A spinal CSF leak can be caused by one or more meningeal diverticula or CSF-venous fistulas not associated with an epidural leak.
Ultrasound-guided lumbar puncture is a medical procedure used in some emergency departments to obtain cerebrospinal fluid for diagnostic purposes. In contrast to standard lumbar puncture by palpation , the use of ultrasound imaging may reduce the number of failed punctures, needle insertions, and needle redirections. [ 1 ]
There are many cisterns in the brain with several large ones noted with their own name. At the base of the spinal cord is another subarachnoid cistern: the lumbar cistern which is the site for a lumbar puncture. Some major subarachnoid cisterns: Cisterna magna also called cerebellomedullary cistern - the largest of the subarachnoid cisterns.
Given normal anatomy, the intracranial pressure will be reflected as a rapidly rising pressure measured from the lumbar needle, within 10–12 seconds. If there is a stenosis in the spine, there will be a damped, delayed response in the lumbar pressure, thus a positive Queckenstedt's maneuver.
