2023年7月17日 · A transtentorial herniation is the movement of brain tissue from one intracranial compartment to another. This includes uncal, central, and upward herniation. These are life-threatening and time-critical pathologies that may be reversible with emergent surgical intervention and medical management.

Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull.

2021年1月14日 · Transtentorial herniation is a type of cerebral herniation broadly divided into two major types based on the direction of herniation: downwards due to supratentorial mass effect and upward due to infratentorial mass effect.

2023年8月13日 · Central involves herniation of both temporal lobes through the tentorial notch. A tonsillar herniation is caused by an infratentorial mass, forcing the cerebellar tonsils through the foramen magnum. Upward herniation occurs when an …

Brain herniation occurs when increased intracranial pressure causes the abnormal protrusion of brain tissue through openings in rigid intracranial barriers (eg, tentorial notch).

2023年8月8日 · Uncal herniation occurs when rising intracranial pressure causes portions of the brain to move from one intracranial compartment to another. It is a life-threatening neurological emergency and indicates the failure of all adaptive mechanisms for intracranial compliance.

2024年7月7日 · Brain herniation is the displacement of part of the brain through an opening or across a separating structure into a region that it does not normally occupy. TYPES. Supratentorial. 1. Uncal transtentorial herniation. 2. Central tentorial herniation. 3. Subfalcine herniation. 4. Transcalvarial herniation. Infratentorial. 5.

2024年9月30日 · Transtentorial herniation: This occurs when brain tissue from the cerebral hemispheres gets pushed downward through the tentorial notch, a small opening in the tentorium cerebelli (another membrane separating parts of the brain).

2023年7月17日 · A transtentorial herniation is any parenchymal herniation through the tentorial notch; of which there are three kinds: Copyright © 2025, StatPearls Publishing LLC. Brain herniation is the movement of brain parenchyma from one cranial compartment to another.

2024年11月10日 · There are a number of different patterns of brain herniation that describe the type of herniation occurring: subfalcine herniation. transalar herniation: ascending and descending. transtentorial herniation. downward: uncal herniation and central herniation. upward: ascending transtentorial herniation. tonsillar herniation
