Epidural Hemorrhage Anatomical Correlation Clinical Features And Pathophysiology
Epidural hemorrhage or Extradural hemorrhage occurs when there is hemorrhage in the extradural space.
Extradural space lies between the periosteal layer and meningeal layer of the dura matter.
These two layers are very close to each other but there is potential space between them.
These layers are held tightly together at skull sutures.
In some places, these two layers separate making venous dural sinuses.
Anterior branch of middle meningeal artery and vein runs between two layers of dura matter.
When there is rupture of anterior branches of middle meningeal artery or vein due to trauma, epidural hematoma occurs and
expands between skull bone and meningeal layer of dura making a biconvex shape or crescent shape hematoma.
Hematoma does not expand beyond skull sutures
Clinically epidural hematoma presents with 'Lucid interval'
Lucid interval is a phenomenon in which a person initially loses consciousness after trauma to the head but immediately regains consciousness and then there is progressive
loss of consciousness.
Ct scan is the modality of choice in diagnosing epidural hemorrhage.
Surgical intervention (burr hole craniotomy) is the treatment of choice.
