Metabolic penumbra in intracerebral hemorrhage.
See related article, pages 1638–1643. In the past decade there has been considerable scientific discussion about the metabolic state of the tissue surrounding a brain hemorrhage. The scientific discussion has focused mostly on the question of whether brain ischemia is present in this “penumbral tissue,” which has great clinical relevance because the presence of ischemia would drive clinical tre...
متن کاملIs there a penumbra surrounding intracerebral hemorrhage?
hemorrhagic tissue damage rather than surrounding ischemia. Pascual et al. [10] now add to this data bank with their experience from dedicated follow-up MRI, which fits previous evidence. Their figures nicely demonstrate two important issues to consider: cortical and subcortical areas appear remarkably normal and wider areas of hypoperfusion as expected in middle cerebral artery obstruction are...
متن کاملStroke MRI in intracerebral hemorrhage: is there a perihemorrhagic penumbra?
BACKGROUND AND PURPOSE Cerebral ischemia has been proposed as a contributing mechanism to secondary neuronal injury after intracerebral hemorrhage (ICH). The search for surrogate parameters that allow treatment stratification for spontaneous ICH continues. We sought to assess the presence and prognostic effect of perihemorrhagic ischemic changes and hypoperfusion in a prospective stroke MRI stu...
متن کاملIntracerebral hemorrhage.
Intracerebral hemorrhage (ICH) accounts for 10 to 15% of all strokes, but results in a disproportionately high morbidity and mortality. Although chronic hypertension accounts for the majority of ICH, other common causes include cerebral amyloid angiopathy, sympathomimetic drugs of abuse, and underlying cerebral vascular anomalies. Validated baseline predictors of clinical outcome after ICH incl...
متن کاملIntracerebral hemorrhage.
Intracerebral hemorrhage (ICH) represents a significant fraction of all strokes and causes a disproportionate amount of stroke related morbidity and mortality, especially in young blacks. While diagnosis of this disorder has greatly improved in the CT era, morbidity and mortality remain essentially unchanged. Not one currently utilized therapeutic modality has been clearly associated with a ben...
