epidural hemorrhage

epidural hemorrhage

a hemorrhage that produces a collection of blood outside the dura mater of the brain or spinal cord. It usually results from tearing of the middle meningeal artery and may be rapidly life threatening. Also called extradural hemorrhage.

epidural hemorrhage

Haemorrhage into the epidural space, which occurs in 10% of patients with severe head trauma; 80% are associated with skull fractures, especially of the temporal bone; many of these disrupt the middle meningeal artery, veins, dural-venous sinuses, and skull vessels.

Clinical findings
Continued bleeding causes intracranial hypertension, uncal herniation and, if untreated, death.
