Decompressive Hemicraniectomy in Patients With Transtentorial Herniation
✔ Objective: To present the results, technique and indications of decompressive hemicraniectomy in patients with unilateral transtentorial herniation. Methods: Ten consecutive patients with intracranial hypertension refractory to medical management and transtentorial herniation were treated with decompressive hemicraniectomy over a 3-year period with the following diagnoses: malignant infarctio...

متن کاملThe "keyhole": a sign of herniation of a trapped fourth ventricle and other posterior fossa cysts.
When a cystic structure in the posterior fossa increases in size, the accompanying increase in pressure may cause it to herniate upward through the tentorial hiatus. In our experience this happens most commonly with a dilated trapped fourth ventricle secondary to infection or intraventricular hemorrhage. However, herniation of an arachnoid cyst or a Dandy-Walker malformation through the tentori...
متن کاملIntracranial pressure in a case of isolated fourth ventricle.
Since the report by Lundberg (1960), the importance of analysis of pressure waves has been recognized with respect to the intracranial pressure, apart from the level of pressure. More recently, various instruments for measuring the intracranial pressure have been developed and measurements of the extradural and intraventricular pressure have become relatively easy. At the same time, efforts to ...
متن کاملTranstentorial herniation after unilateral infarction of the anterior cerebral artery.
BACKGROUND Fatal cerebral herniation is a common complication of large ("malignant") middle cerebral artery infarcts but has not been reported in unilateral anterior cerebral artery (ACA) infarction. CASE DESCRIPTION We report a 47-year-old woman who developed an acute left hemiparesis during an attack of migraine. Cranial CT (CCT) was normal but demonstrated narrow external cerebrospinal flu...
