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. Downward herniation occurs when there is mass effect upon or from within the cerebral hemispheres.

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.

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 …

Tentorial herniation is a serious symptom, especially since the brainstem is likely to be compressed as well if the intracranial pressure rises further. A common type of herniation is uncal herniation .

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

2019年10月7日 · Brain herniation syndromes are commonly classified on the basis of their location as intracranial and extracranial hernias. Intracranial hernias can be further divided into three types: (a) subfalcine hernia; (b) transtentorial hernia, which can be ascending or descending (lateral and central); and (c) tonsillar hernia.

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.

2023年7月17日 · The tentorium cerebelli contains an oval-shaped opening called the tentorial notch or incisor. The midbrain passes through this opening and is continuous with the diencephalon. A transtentorial herniation is any parenchymal herniation through the tentorial notch; of which there are three kinds:

transtentorial herniation downward displacement of medial brain structures through the tentorial notch by a supratentorial mass, exerting pressure on the underlying structures, including the brainstem; this is a life-threatening situation because of pressure on the third cranial nerve, with symptoms including dilated, nonreactive pupils, ptosis ...
