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 ...
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 ]

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).
Heinrich Irenaeus Quincke (26 August 1842 – 19 May 1922) was a German internist and surgeon.His main contribution to internal medicine was the introduction of the lumbar puncture for diagnostic and therapeutic purposes.
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]
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
Raised intracranial pressure, if severe or threatening vision, may require therapeutic lumbar puncture (removal of excessive cerebrospinal fluid), or neurosurgical treatment (optic nerve sheath fenestration or shunting). [3] Venous stenting is emerging as a minimally invasive, safer alternative to shunting. [21]
