Trauma is a common cause of spinal epidural hematoma. Non-trauma causes include anticoagulant therapy, hemophilia, liver disease, aspirin use, systemic lupus erythematosus.
An epidural hematoma is a pocket of blood that forms immediately outside the dura mater. The dura mater is the fibrous outermost sheath or membrane that encloses the brain and spinal cord.
Head swelling, asperation,as well as sudden urge to quit playing (for children),
blood accumulation that separates the dura from the inner side of the skull is known as an epidural hematoma (blood swelling). The same process occurrence between the dura and arachnoid layers is a subdural hematoma
Epidural hematomas usually form when a violent blow breaks a blood vessel in the space outside the dura mater, whether in the skull or in the spinal column.
A Subdural Hematoma occurs when a severe acceleration to deceleration occurs leading to the veins in the subdural space tearing. An Epidural Hematoma occurs from direct trauma to the brain leading to bleeding in the meningeal artery.
Epidural hematoma
You have the meninges to cover the brain and spinal cord. Meninges composed of three layers. Outer most is tough and called as dura matter. Extradural means between the dura matter and the skull. Typically the middle meningeal artery brakes to give you that extradural hematoma. It is also called as epidural hematoma. The British spell it as haematoma. The US should spell it as hematoma, I guess.
If the patient is having epidural anesthesia, the risks include bleeding into the spinal canal, nerve damage, or a spinal headache.
An epidural and a spinal tap (lumbar puncture) are both procedures involving the spine but serve different purposes. An epidural involves injecting anesthetic medication into the epidural space to provide pain relief during labor or surgery, while a spinal tap involves inserting a needle into the subarachnoid space to collect cerebrospinal fluid for diagnostic purposes. The epidural is typically administered in the lower back, while the spinal tap is performed in a similar area but targets a different spinal layer. Additionally, an epidural can be a continuous infusion, whereas a spinal tap is usually a single-event procedure.
Epidural Space
No, The risks of bleeding into the epidural space and causing decrease blood supply to your spinal cord by mechanical compression is to great.
Essentially, when a spinal tap is given, a needle is inserted into the spinal canal in the lumbar area, medicine (or an anesthetic) is inserted directly into the cerebrospinal fluid (CSF). Numbness is usually immediate. However, in an epidural, a hollow needle and a catheder are inserted into space between the spinal column and the outer membrane of the spinal cord (EPIDURAL space). Hence the name "epidural".
