Intracranial hemorrhage is a serious medical emergency because the buildup of blood within the skull can lead to increases in intracranial pressure, which can crush delicate brain tissue or limit its blood supply. Severe increases in intracranial pressure (ICP) can cause brain herniation, in which parts of the brain are squeezed past structures ...
Subdural hematoma. A subdural hematoma (SDH) is a type of bleeding in which a collection of blood —usually but not always associated with a traumatic brain injury —gathers between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. It usually results from tears in bridging veins that cross the ...
The risk of death from an intraparenchymal bleed in traumatic brain injury is especially high when the injury occurs in the brain stem. [48] Intraparenchymal bleeds within the medulla oblongata are almost always fatal, because they cause damage to cranial nerve X, the vagus nerve, which plays an important role in blood circulation and breathing ...
Intraparenchymal hemorrhage (IPH) is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage (IVH). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders.
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 ...
SAH is a frequent occurrence in traumatic brain injury and carries a poor prognosis if it is associated with deterioration in the level of consciousness. [19] While thunderclap headache is the characteristic symptom of subarachnoid hemorrhage, less than 10% of those with concerning symptoms have SAH on investigations. [2]
Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke. 30% of intraventricular hemorrhage (IVH) are primary ...
Cerebral contusion. 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. Contusion occurs in 20–30% of severe head injuries. [3]
