Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. [4] When this condition occurs in the spinal canal, it is known as a spinal epidural hematoma. [4] There may be loss of consciousness following a head injury, a brief regaining of consciousness, and then loss of ...
Subdural hematoma maybe less acute than epidural hematoma due to slower blood accumulation, but it still has the potential to cause brain herniation that may require surgical evacuation. [3] Clinical features depend on the site of injury and severity of injury. Patients may have a history of loss of consciousness but they recover and do not ...
In addition, some patients may develop "pseudoaneurysms" after trauma which can eventually burst and bleed, a factor which might account for the delay in loss of consciousness. [ 4 ] Because a patient may have a lucid interval, any significant head trauma is regarded as a medical emergency and receives emergency medical treatment even if the ...
Subarachnoid hemorrhage approximately doubles mortality. [142] Subdural hematoma is associated with worse outcome and increased mortality, while people with epidural hematoma are expected to have a good outcome if they receive surgery quickly. [76] Diffuse axonal injury may be associated with coma when severe, and poor outcome. [10]
Lacerations to the scalp and resulting hemorrhage of the skin; Traumatic subdural hematoma, a bleeding below the dura mater which may develop slowly; Traumatic extradural, or epidural hematoma, bleeding between the dura mater and the skull; Traumatic subarachnoid hemorrhage; Cerebral contusion, a bruise of the brain; Concussion, a loss of ...
The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency.
[10] Hemorrhage into the basal ganglia or thalamus causes contralateral hemiplegia due to damage to the internal capsule. [7] Other possible symptoms include gaze palsies or hemisensory loss. [7] Intracerebral hemorrhage into the cerebellum may cause ataxia, vertigo, incoordination of limbs and vomiting. [7]
This subdural hematoma/epidural hematoma (arrows) is causing midline shift of the brain Doctors detect midline shift using a variety of methods. The most prominent measurement is done by a computed tomography (CT) scan and the CT Gold Standard is the standardized operating procedure for detecting MLS. [ 5 ]
