Interesting Case -

Hey all,

Read about a great case seen by our very own Phil, complete with some quiz questions and teaching points. (more…)

The Epidural Hematoma:

Results from bleeding between the dura and the inner surface of the skull.  It is considered a neurological emergency.

These types of hematomas are usually associated with linear fracture crossing a major artery in the dura, which causes a tear.  They can have a venous or an arterial origin.

Venous epidural hematomas are associated with a tear of the dural venous sinus and develop slowly.

With arterial hematomas, the middle meningeal artery lying under the temporal bone is often torn.  Because it is an arterial bleed, the hematoma develops rapidly and under high pressure.

Classic Signs:

-Include an initial period of unconsciousness at the scene, with a brief lucid interval followed by a decreased LOC.

-Headache, nausea, and vomiting.

Treatment:

Rapid surgical intervention to evacuate the hematoma and prevent cerebral herniation, along with medical management for increasing ICP can improve outcomes.
