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 ...
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]
Lumbar puncture is done before injected contrast into the thecal sac. However, it is dangerous to do lumbar puncture in those who have raised intracranial pressure (ICP). [3] For those who had recently done lumbar puncture in one week time, there may be some cerebrospinal fluid (CSF) accumulates in the subdural space.
Repeated lumbar punctures are regarded as unpleasant by people, and they present a danger of introducing spinal infections if done too often. [5] [7] Repeated lumbar punctures are sometimes needed to control the ICP urgently if the person's vision deteriorates rapidly. [9]
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.
Prior to this decision, Medicare only covered cerebrospinal fluid tests, which require a lumbar puncture, to determine amyloid plaque in the brain. Co-pays for diagnostic testing under Medicare ...
More commonly, decreased ICP is the result of lumbar puncture or other medical procedure involving the spinal cord. Various medical imaging technologies exist to assist in identifying the cause of decreased ICP. Often, the syndrome is self-limiting, especially if it is the result of a medical procedure.
