Meningeal coverings and  Epidural vs. subdural bleed


Updated 6/24


An epidural bleed is an arterial bleed. The patient has a brief period of unconsciousness following injury. He then becomes lucid and quickly progresses to unconsciousness and possible coma. A common site for injury is the meningeal artery which runs close to the surface, behind the ear.

A subdural bleed is venous and progresses slowly. The patient may not experience any symptoms for a few days. It may even become chronic. Suspect a subdural bleed , if the patient had a fall / head injury and was initially okay, then later becomes unconscious. It is common in alcoholics.
