When tentorial herniation occurred, the direct pressure of both unci fell upon the posterior cerebral arteries on both sides, or these arteries became stretched and kinked. Ischemic changes consequently occurred in the occipital lobes, which depend for their blood supply on these arteries.

Note the midline shift and uncal herniation, as the uncus (medial temporal lobe) is displaced 26 Aug 2020 A transtentorial herniation is any parenchymal herniation through the tentorial notch; of which there are three kinds: ResearchGate Logo.

Tentorial herniation

Transtentorial herniation is the unilateral or bilateral displacement of the parahippocampal gyrus of the occipital lobe(s) beneath the tentorium cerebelli, resulting Ascending transtentorial herniation. The cerebellum and the brainstem move upward through a notch in a membrane called the tentorium cerebelli.

Occipital lobe infarction caused by tentorial herniation. Sato M, Tanaka S, Kohama A, Fujii C. Occipital lobe infarction caused by tentorial herniation was described based on computed tomography findings in nine patients. The whole area of the occipital lobe was involved in five patients; some areas were spared in the others.

T This is when one hemisphere or both External ventriculostomy: a practical application for the acute care nurse Acute hyperventilation should only be used as a rescue measure to prevent tentorial herniation when all other modalities have failed to alleviate an acute rise in ICP. Transtentorial herniation has been investigated with computed tomography using the three calcification relationship and descent through the tentorial opening could not be documented. Bilateral brain stem compression in acute bilateral cases must be distinguished from herniation.
