Feb 24, 2024 · Duret hemorrhages are small, usually multiple, hemorrhages in the midbrain or pons resulting from rapidly developing brain herniation, especially central herniation . They generally have a dismal prognosis.
Nov 1, 2022 · Duret hemorrhage is reported most frequently with increases in intracranial pressure from diverse etiologies, including subdural, epidural, intraparenchymal hemorrhages, trauma, brain neoplasms, acute diffuse cerebral edema, hyponatremia and rarely following administration of thrombolytics.
Duret haemorrhages are haemorrhages secondary to raised intracranial pressure with formation of a transtentorial pressure cone involving the front part of the cerebral peduncles, the cerebral crura. Increased pressure above the tentorium may also involve other midbrain structures.
Jul 15, 2023 · Duret hemorrhages are a serious complication of increased intracranial pressure, typically associated with brain herniation. Early recognition, prompt medical intervention, and appropriate surgical measures are essential for managing this life-threatening condition.
Nov 1, 2022 · Duret hemorrhage is reported most frequently with increases in intracranial pressure from diverse etiologies, including subdural, epidural, intraparenchymal hemorrhages, trauma, brain neoplasms, acute diffuse cerebral edema, hyponatremia and rarely following administration of thrombolytics.
Nov 1, 2022 · Primary hemorrhages result from direct trauma, hypertension, coagulopathy, whereas secondary hemorrhages may result from descending transtentorial herniation from diverse etiologies. The latter is known as Duret hemorrhages (DH) named after a French neurologist Henri Duret, who first described the distribution of arterial supply in the ...
Sep 24, 2023 · Duret hemorrhage is a rare but potentially life-threatening condition that results from bleeding in the brainstem. Prompt recognition of symptoms and immediate medical intervention are crucial for a favorable outcome.
Sep 10, 2020 · Duret haemorrhage, also known as secondary brainstem haemorrhage, occurs as a result of transtentorial herniation of the brain in the context of acute trauma (eg, subdural haematoma). 1 2 It is hypothesised to occur as a result of the downward pressure shearing small mobile blood vessels within the brainstem from the relatively immobile basilar ...
Associated with uncal herniation, a delayed focal and very severe hemorrhagic lesion in the brainstem occurs and is revealed by CT or to better advantage by MR. This lesion, called Duret hemorrhage ( Figure 12-28 ), is different from contusive lesions and brainstem DAI.
Sep 17, 2012 · Generally, a Duret hemorrhage is considered a serious, often fatal, complication of brain herniation, 1 however, subtle neurologic deficits, such as internuclear ophthalmoplegia, may be its only sign.
