The anatomy term "epidural space" has its origin in the Ancient Greek language; ἐπί, "on, upon" + dura mater also known as "epidural cavity", "extradural space" or "peridural space". In humans the epidural space contains lymphatics , spinal nerve roots, loose connective tissue , adipose tissue , small arteries , dural venous sinuses and a ...
Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter. ICD-9-CM 03.90 MeSH D000767 OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method ...
The epidural venous plexus is a venous plexus embedded within the epidural fat of the vertebral canal. [1] It is situated within the anterior epidural space (the outermost part of the spinal canal). The plexus extends from the skull base to the sacrum. It is surrounded by sparse fat (although its levels increase inferiorly).
For epidural anesthesia an anesthetic agent is injected into the space just outside the thecal sac and diffuses through the dura to the nerve roots where they exit the thecal sac. [4] [5] For spinal anaesthesia in general, an injection can be given intrathecally into the subarachnoid space, or into the spinal canal.
The internal vertebral venous plexuses (intraspinal veins) lie within the vertebral canal in the epidural space, [1] [2] embedded within epidural fat. [2] [3] They receive tributaries from bones, red bone marrow, and spinal cord. They are arranged into four interconnected, vertically oriented vessels - two situated anteriorly, and two ...
An epidural hematoma is a collection of blood between the dura and the inner surface of the skull, and is usually due to arterial bleeding. Intradural procedures, such as removal of a brain tumour or treatment of trigeminal neuralgia via a microvascular decompression, require that an incision is made to the dura mater.
The boy’s mother was knocked under the cab and the still-spinning wheel was on top of the kid’s leg, a tourist visiting from Oregon told ABC 7.. The tourist and others nearby then dropped what ...
The anatomy of the epidural space is such that spinal epidural hematoma has a different presentation from intracranial epidural hematoma. In the spine, the epidural space contains loose fatty tissue and a network of large, thin-walled veins, referred to as the epidural venous plexus.
