Overview:

The movement of the cerebral cortex from one place in the brain to another via different folds and holes is known as brain herniation. Brain damage, stroke, or brain tumour are the most common causes of brain swelling or bleeding. Brain tumours, such as metastatic brain tumours, may cause brain herniation as a secondary effect.

A herniation is a problem with one of the rubber cushions (discs) that sit between your spine’s different bones (vertebrae). Surgery is seldom needed to treat the disease. Brain herniation may occur for some causes. Herniations of the brain come in a variety of shapes and sizes.

Brain damage, stroke, or brain tumour are the most common causes. A herniation is a problem with one of the rubber cushions (vertebrae) that sit between your spine’s different bones. It can occur from one side of the brain to the other, or even through the foramen magnum. Severe migraines and seizures are not uncommon as a consequence of elevated intracranial pressure.

The Brain Trauma Foundation recommends monitoring ICP.ICP and cerebral blood pressure guided treatments have respective thresholds of 22 mm Hg or 60 to 70mm Hg.

Herniations of the brain come in a variety of shapes and sizes. The location of the displaced brain tissue may be used to classify a brain herniation.

 There are three kinds of herniation in the brain:

 

  • Subfalcine: Brain tissue travels under the falx cerebri, a membrane in the centre of the brain. Brain tissue gets moved to the opposite side of the brain. The most frequent form of brain herniation is this one.
  1. Transtentorial or uncal descent: The uncus, which is a component of the occipital lobe, is pushed lower into the posterior fossa. The second most frequent form of brain herniation is this one.
  2. Transtentorial herniation ascending: The tentorium cerebelli is a hole in a membrane that pores the cerebellum and brainstem to migrate higher.
  • Tonsillar in the cerebellum: The foramen, a natural hole at the skull base where the spinal cord attaches to the brain, allows the cerebellar tonsils to migrate lower.

Causes:

Brain herniation occurs when anything inside the skull puts pressure just on brain tissues. A head injury, strokes, or brain tumour are the most common causes of skull swelling or bleeding.

  • A brain tumour that has spread throughout the body
  • Malignant glioma
  • A bacteria infection causes a collection of mucus and other substances in the brain (abscess)
  • Subdural hematoma (bleeding in the brain) (haemorrhage)

Brain herniation may occur for some reasons:

 

Down, beneath, and over a stiff membrane such as the hub contains or falx, either from one side to the other. Through incisions made during surgery on the brain. We have to live a happy and healthy life by avoiding these reasons.

Abnormal posture, a distinctive alignment of the limbs suggestive of serious brain injury, is a common symptom of brain herniation. Patients with Glasgow Baseline Scores of 3 to 5 have a reduced degree of awareness. 

Vomiting may also cause by the medulla oblongata’s vomiting centre compress. Severe migraines and seizures are not uncommon as a consequence of elevated intracranial pressure. Even as the brain loses function, cardiac and pulmonary signs may appear, but they may also link to bleeding. Hypertension, respiratory depression, arrhythmia, and, in extreme instances, cardiac arrest are among them.

Management / Treatment:

On individuals with symptomatic Concussion [Glasgow coma score (GCS) of 3 to 8] who have either (1) anomalies in CT of a head or (2) satisfy at least two things three criteria, the Brain Trauma Foundation recommends monitoring ICP.

Only level IIA evidence for the function of decompressive hemicraniectomy and grade IIB evidence for the importance of ICP monitoring exists for any treatments aimed at treating refractory intracranial hypertension. ICP and cerebral blood pressure guided treatments have respective thresholds of 22 mm Hg or 60 to 70 mm Hg.

Treatment of refractory hypertension and the resulting brain herniation have propose:

  1. Mass lesions must evacuate.
  2. Physiological neuroprotection is the second kind of neuroprotection.
  3. Analgesics, sedation, and ventilation.
  4. Drainage of CSF.
  5. Osmotherapy.
  6. Hyperventilation.
  7. Hypothermia.
  8. Barbiturate-induced coma.
  9. Hemicraniectomy with decompression.
