Microsurgical anatomy of the superior petrosal venous complex: new classifications and implications for subtemporal transtentorial
and retrosigmoid suprameatal approaches.
Prevention of postoperative visual field defect after the occipital transtentorial
approach: anatomical study.
As a result, all these pathologies cause severe cerebral damage resulting in decreased cerebral perfusion and transtentorial
herniation in response to cerebral oedema formation and increased intracranial pressure.
(8,9) Serial pupillometer values have been shown to correlate with intracranial pressure (ICP) (4,10,11) and signs of transtentorial
brain herniation (12) and may be an important predictor of outcome after cardiac arrest.
The neuroimaging revealed a large intraaxial heterogeneous mass lesion in the left frontal and anterior parietal lobe associated with a 1.3 cm right midline shift, effacement of suprasellar cistern, and obliteration of the perimesencephalic cistern likely representing transtentorial
In the absence of unilateral subdural hematomas, most cases of IH produce central incisural herniation, rather than the more common asymmetric, or paracentral downward transtentorial
herniation typically associated with asymmetric supratentorial mass effect.
Brainstem hemorrhage in descending transtentorial
herniation (Duret hemorrhage).
Results are often nonspecific and neurologic decline as well as transtentorial
herniation after lumbar puncture has been well documented and can lead to fatal consequences [4, 7, 8].
Traystman, "Treatment of transtentorial
herniation unresponsive to hyperventilation using hypertonic saline in dogs: effect on cerebral blood flow and metabolism," Journal of Neurosurgical Anesthesiology, vol.
herniation was seen in 4 cases (6%).
