Association of Pediatric ASPECTS and NIH Stroke Scale, Hemorrhagic Transformation, and 12-Month Outcome in Children With Acute Ischemic Stroke.

2021 
Background and Objectives We aimed to determine whether a modified pediatric Alberta Stroke Program Early CT Score (modASPECTS) is associated with clinical stroke severity, hemorrhagic transformation, and 12-month functional outcomes in children with acute arterial ischemic stroke (AIS). Methods Children (age 29 days– Results One hundred thirty-one children were included; 91 were ≥2 years of age. Median time from stroke to MRI was 1 day (interquartile range [IQR] 0–1 day). Median modASPECTS was 4 (IQR 3–7). ModASPECTS correlated with PedNIHSS score (ρ = 0.40, p = 0.0001). ModASPECTS was associated with hemorrhagic transformation (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.02–1.25, p = 0.018). Among children with follow-up (n = 128, median 12.2 months, IQR 9.5–15.4 months), worse outcomes were associated with higher modASPECTS (common OR 1.14, 95% CI 1.04–1.24, p = 0.005). The association between modASPECTS and outcome persisted when we adjusted for age at stroke ictus and the presence of tumor or meningitis as stroke risk factors (common OR 1.14, 95% CI 1.03–1.25, p = 0.008). Discussion ModASPECTS correlates with PedNIHSS scores, hemorrhagic transformation, and 12-month functional outcome in children with acute AIS. Future pediatric studies should evaluate its usefulness in predicting symptomatic intracranial hemorrhage and outcome after acute revascularization therapies. Classification of Evidence This study provides Class II evidence that the modASPECTS on MRI is associated with stroke severity (as measured by the baseline PedNIHSS score), hemorrhagic transformation, and 12-month outcome in children with acute supratentorial ischemic stroke.
