How serious is an epidural hematoma?
An epidural hematoma can put pressure on your brain and cause it to swell. As it swells, your brain may shift in your skull. Pressure on and damage to your brain’s tissues can affect your vision, speech, mobility, and consciousness. If left untreated, an epidural hematoma can cause lasting brain damage and even death.
Where is epidural inserted?
With an epidural, your healthcare provider injects anesthesia into the epidural space around your spinal nerves. With a spinal block, your provider injects the anesthesia into the dural sac around your spinal nerves that contains cerebrospinal fluid.
When is epidural given?
It usually takes between 5 and 30 minutes for your pain to be relieved by the epidural. You usually only have an epidural during the first stage of labour — but it can be given at any stage of labour.
Where is epidural injected?
An epidural steroid injection (ESI) is the delivery of powerful anti-inflammatory medicine directly into the space outside of the sac of fluid around your spinal cord. This area is called the epidural space.
What’s the difference between epidural and spinal anesthesia?
Spinal anesthesia involves the injection of numbing medicine directly into the fluid sac. Epidurals involve the injection into the space outside the sac (epidural space).
Who is most at risk for epidural hematoma with head trauma?
Intracranial and spinal epidural hematomas are more frequent in men, with a male-to-female ratio of 4:1. Intracranial epidural hematoma is rare in individuals younger than 2 years. Intracranial epidural hematoma is also rare in individuals older than 60 years because the dura is tightly adherent to the calvaria.
Why epidural Anaesthesia is given?
An epidural anesthetic temporarily numbs the spinal nerves, which then blocks pain signals in a certain region of your body depending on where along your spine your provider injected the epidural. Epidural anesthesia can provide temporary pain relief or a temporary total lack of feeling.
Is epidural painful?
Does it hurt when the epidural is administered? The physician anesthesiologist will numb the area where the epidural is administered, which may cause a momentary stinging or burning sensation. But because of this numbing, there is very little pain associated with an epidural injection.

What is middle meningeal artery embolization?
Middle meningeal artery embolization. The goal of middle meningeal artery (MMA) embolization is to devascularize the subdural membranes to a sufficient extent such that the balance is shifted from the continued leakage and accumulation of blood products towards reabsorption.
Where does the middle meningeal artery originate?
Vidian Branch origin of the Middle Meningeal Artery In the following case, the MMA does not originate from the stapedial branch, but more anteriorly, from the mid-section of the horizontal petrous segment, in the expected location of the vidian artery origin.
What does the posterior meningeal artery supply?
The artery of the tentorium cerebelli (red) gives rise to the posterior meningeal artery, whose territory has considerably extended due to bilateral MMA sacrifice, demonstrating an impressive meningeal network (yellow arrows) Ethmoid Fistula supplied by Superior Sagittal Sinus Artery (white), opacified via frontal branch of MMA (black).
Which CT findings are characteristic of recurrent meningeal artery (MMA)?
On head CT, aberrant MMA origin can be inferred by absence of foramen spinosum on left (blue arrow on “usual” right side) The recurrent meningeal artery travels along the sphenoid ridge (orange arrows) and then over the convexity (red arrows). Again, only frontal branch is seen
