Hemispheric edema
Web4 feb. 2024 · Cytotoxic edema refers to the brain swelling caused by ions (Na +, Cl −) and water entering the cells of neurons or astrocytes ( Rungta et al., 2015 ). Cytotoxic edema occurs quickly after brain tissue ischemia, causing intracellular swelling without increasing the brain tissue volume ( Liebeskind et al., 2024 ). WebHemispheric Stroke Patients with significant swelling typically have occlusions of the internal carotid artery, MCA, or both. The natural history of a large infarction after internal carotid artery versus MCA infarction is not clear, especially when independent of anterior cerebral artery territory infarction.

This endpoint is limited by the fact that MLS is used in both the scoring criteria and the outcome measure. Moreover, death is frequently confounded by withdrawal of care, which has both cultural and regional variation. WebWe recently identified a nonselective cation channel, the NC (Ca-ATP) channel, in ischemic astrocytes that is regulated by sulfonylurea receptor 1 (SUR1), is opened by depletion of ATP and, when opened, causes cytotoxic edema. Here, we evaluated involvement of this channel in rodent models of stroke.
