Hydrocephalus in posterior fossa lesions: ventriculostomy and permanent shunt rates by diagnosis.
The rate of ventriculostomy for acute hydrocephalus and progression to shunt-dependent chronic hydrocephalus in patients with posterior fossa lesions are not well known. ⋯ Acute primary posterior fossa hemorrhage has the highest rate of ventriculostomy for acute hydrocephalus and highest inpatient mortality but a surprisingly low rate of permanent shunt-dependency. When hydrocephalus was caused by a neoplasm, there was a higher rate of permanent shunt placement.

Early post-ischemic hyperemia on transcranial cerebral oxygen saturation monitoring in carotid endarterectomy is associated with severity of cerebral ischemic insult during carotid artery clamping.
In animal models, the magnitude of early post-ischemic hyperemia tends to correlate with the duration and intensity of prior ischemic insult. The aim of this study was to determine whether early post-ischemic hyperemia in human brain during carotid endarterectomy (CEA) is associated with the severity of cerebral ischemic insult during clamping of the internal carotid artery (ICA). ⋯ Early post-ischemic hyperemia in CEA is correlated with the severity of cerebral ischemic insult during clamping of the ICA.
