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 ...
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 ...
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 ...
Epidural hematoma involves bleeding into the area between the skull and the dura mater, the outermost of the three membranes surrounding the brain. [11] In subdural hematoma, bleeding occurs between the dura and the arachnoid mater. [23] Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater ...
Mass effect such as brain tumor, infarction with edema, contusions, subdural or epidural hematoma, or abscesses all tend to deform the adjacent brain. [citation needed] Generalized brain swelling can occur in ischemic-anoxia states, acute liver failure, [9] hypertensive encephalopathy, hypercarbia (hypercapnia), and Reye hepatocerebral syndrome ...
Epidural hemorrhage is bleeding between the dura mater and the skull. [4] It is commonly associated with damage to the middle meningeal artery, often resulting from a skull fracture. Subdural hemorrhage is bleeding between the dura mater and the arachnoid. [4] Intracerebral hemorrhage is bleeding within the brain tissue itself. [4]
Cerebral edema is commonly seen in a variety of brain injuries including ischemic stroke, subarachnoid hemorrhage, traumatic brain injury, subdural, epidural, or intracerebral hematoma, hydrocephalus, brain cancer, brain infections, low blood sodium levels, high altitude, and acute liver failure.
intracranial hematoma – a condition in which a blood vessel ruptures causing a pool of blood to form around the brain (subdural hematoma) or between the brain and the skull (epidural hematoma). Intracranial hematoma causes an increase in pressure on the brain and requires immediate medical attention. [5]
