CT indicates computed tomography; CTA, computed tomographic angiography; FCAi, focal cerebral arteriopathy of inflammatory subtype; ICA, internal carotid artery; M1 and M2, middle cerebral artery segments M1 and M2; mRS, modified Rankin Scale; PedNIHSS, Pediatric National Institutes of Health Stroke Scale; post, 12–24 hours after admission; pre, on admission.
The ASPECTS (Alberta Stroke Program Early Computed Tomography Score) is an imaging measure of the extent of ischemic stroke. Scores range from 0 to 10, with higher scores indicating a smaller infarct core.
Scores on PedNIHSS range from 0 to 42, with higher scores indicating more severe neurologic deficits.
Modified Treatment in Cerebral Infarction Score (mTICI) reaches from 0 (no reperfusion) to 3 (complete reperfusion).
Scores on the modified Rankin Scale (mRS) of functional disability range from 0 (no symptoms) to 6 (death). A score of 2 or less indicates functional independence.
Scores on Pediatric Stroke Outcome Measure (PSOM) range from 0 to 10, with higher scores indicating more severe neurologic deficits.
