For what purpose is a Suboccipital puncture performed?
Table of Contents
Suboccipital puncture is a procedure that was developed at the beginning of the last century. It was designed to obtain cerebrospinal fluid (CSF) for diagnostic and therapeutic purposes as an alternative to lumbar puncture. It was performed through a midline puncture below the occipital bone.
What are the indications for lumbar puncture?
Indications – Lumbar puncture (LP) is essential or extremely useful in the diagnosis of bacterial, fungal, mycobacterial, and viral central nervous system (CNS) infections and, in certain settings, for help in the diagnosis of subarachnoid hemorrhage (SAH), CNS malignancies, demyelinating diseases, and Guillain-Barré …
What is Cisternal puncture?
Cisternal puncture uses a needle placed below the occipital bone (back of the skull). It can be dangerous because it is so close to the brain stem. It is always done with fluoroscopy. Ventricular puncture may be recommended in people with possible brain herniation.
What are the indications and contraindications for lumbar puncture?
Absolute contraindications for performing a LP include infected skin over the puncture site, increased intracranial pressure (ICP) from any space-occupying lesion (mass, abscess), and trauma or mass to lumbar vertebrae.
What does cisterna magna mean?
The cisterna magna (or cerebellomedullar cistern) is one of three principal openings in the subarachnoid space between the arachnoid and pia mater layers of the meninges surrounding the brain. The openings are collectively referred to as the subarachnoid cisterns.
What is Ventricular puncture?
a surgical procedure in which an opening from the outside is made to the lateral ventricle areas of the brain. The procedure may be performed in order to reduce intracranial pressure, to inject medications (e.g., antibiotics) directly into the brain, or to obtain cerebrospinal fluid.
What is the significance of a spinal tap to meningitis?
Spinal tap (lumbar puncture). For a definitive diagnosis of meningitis, you’ll need a spinal tap to collect cerebrospinal fluid (CSF). In people with meningitis, the CSF often shows a low sugar (glucose) level along with an increased white blood cell count and increased protein.
What is the meaning of Cisternae?
a : one of the large spaces under the arachnoid membrane. b : one of the flattened vesicles comprising the Golgi apparatus and the part of the endoplasmic reticulum studded with ribosomes.
What are the possible complications of puncture of the cisterna magna?
The puncture of the cisterna magna is a simple procedure, but it always carries a small risk of inadvertently needling the spinal cord or a blood vessel. The puncture of the cord may be accompanied by transient paraesthesiae or pain radiating down the body or a limb; serious or permanent disability because of initiation of hematomyelia is rare.
What is lateral C1 C2 puncture used for?
OBJECTIVE. Lateral C1–C2 puncture can be used for CSF collection, contrast agent injection for myelography, and access for cordotomy. The objective of this article is to describe the indications, technique, and potential complications of this procedure.
What is the procedure for CSF collection after puncture?
If the purpose of the procedure is CSF collection, the appropriate amount of CSF is collected, the stylet is returned to the needle hub, and the needle is removed. The puncture site is cleaned and a bandage is applied.
What should be taken into consideration when performing thecal sac puncture?
Also, if the spinal needle is used, care should be taken to make sure that the stylet is reinserted securely before thecal sac puncture. Fluoroscopic or CT images with the anesthetic needle in position are obtained to determine adjustments that may need to be made to the puncture site.
