Overview
Pathophysiology
Pathogenesis
- Epidural hematoma is the result of the bleeding within the epidural space, which lies between dura mater and skull bone.[1]
- The main cause of epidural hematoma is typically head injury that results in a break of the temporal bone and bleeding from the middle meningeal artery in the epidural space.[2][3]
- Because the bleeding is caused by arterial rupture, it has a high tendency to progress and it causes a hematoa in epidural space.
- Progression of bleeding may expand the hematoma and cause increasing of the intracranial pressure and it may lead to brain herniation.[4]
- Occasionally epidural hematoma may occur as a result of a bleeding disorder or blood vessel malformation or after CNS surgery and sometimes is may occur spontaneously.[5][6][7]
