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 ]
Use of ultrasound reduces the number of needle insertions and redirections, and results in higher rates of successful lumbar puncture. [28] If the procedure is difficult, such as in people with spinal deformities such as scoliosis, it can also be performed under fluoroscopy (under continuous X-ray imaging).
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]
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.
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).
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 ...

Lumbar puncture (LP) is the gold standard technique for determining aneurysm rupture (subarachnoid hemorrhage). Once an LP is performed, the CSF is evaluated for RBC count , and presence or absence of xanthochromia .
