Cerebral edema is a severe complication of acute brain injuries, most notably ischemic stroke and traumatic brain injuries, and a significant cause of morbidity and mortality. [ 3 ] [ 10 ] [ 34 ] Cerebral edema is the cause of death in 5% of all patients with cerebral infarction and mortality after large ischemic strokes with cerebral edema is ...
cerebral edema , transtentorial herination Cerebral contusion ( Latin : contusio cerebri ), a form of traumatic brain injury , is a bruise of the brain tissue. [ 2 ] Like bruises in other tissues, cerebral contusion can be associated with multiple micro hemorrhages , small blood vessel leaks into brain tissue.
Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2] The strongest risk factor for intraparenchymal hemorrhage associated with cerebral amyloid angiopathy is old age, and cerebral amyloid angiopathy is most frequently seen in patients who already have, or will soon be diagnosed with, dementia. [3]
Once ruptured, it results in intraparenchymal hemorrhage, intraventricular hemorrhage and SAH. Rupture of cerebral AVM often occurs in young people and children. Cerebral AVM can be diagnosed by computed tomography angiography (CTA) brain, magnetic resonance angiography (MRA) brain, or digital subtraction angiography (DSA). DSA is important to ...
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology. [11]
One of the most damaging aspects of brain trauma and other conditions, directly correlated with poor outcome, is an elevated intracranial pressure. [10] ICP is very likely to cause severe harm if it rises too high. [11] Very high intracranial pressures are usually fatal if prolonged, but children can tolerate higher pressures for longer periods ...
[7] [50] Perihematomal edema, or secondary edema surrounding the hematoma, is associated with secondary brain injury, worsening neurological function and is associated with poor outcomes. [7] Intraventricular hemorrhage, or bleeding into the ventricles of the brain, which may occur in 30–50% of patients, is also associated with long-term ...
Herniation can be caused by a number of factors that cause a mass effect and increase intracranial pressure (ICP): these include traumatic brain injury, intracranial hemorrhage, or brain tumor. [1] Herniation can also occur in the absence of high ICP when mass lesions such as hematomas occur at the borders of brain compartments. In such cases ...
