Brain herniation occurs in cerebral hemorrhage, and the prognosis is related to the location and degree of progression of brain herniation, and the overall prognosis is relatively poor.
Various types of cerebral hemorrhage can cause local hematoma (e.g. subdural hematoma), causing cerebral edema, which in turn leads to increased intracranial pressure, and the brain tissue is squeezed into the cerebellar tentorial fissure, the occipital foramen magnum, and other physiological interstices under the pressure, which triggers cerebral herniation.
When the brain tissue is squeezed into the cerebellar tentorial fissure, it causes cerebellar tentorial incisional hernia, which can be manifested as severe headache, frequent vomiting, limb hemiparesis and other symptoms. When the brain hernia affects the blood supply of the brainstem, it can cause the disappearance of the light reflex, the pupil change, respiratory failure or cardiac arrest, and the prognosis of the late stage is poorer.
Hernia of the occipital foramen magnum is a hernia of brain tissue squeezed into the occipital foramen magnum, which can lead to blockage of cerebrospinal fluid circulatory pathway, causing frequent vomiting, severe headache, and early onset of vital signs disorders, and early onset of respiratory arrest and death, with a poor prognosis in general.
If the patient suspects cerebral hemorrhage, it is recommended to send the patient to the doctor for treatment in time to avoid delaying the condition, leading to the progression of the disease, which may lead to the occurrence of brain hernia.
