Abstract
To describe characteristics of young children with arterial ischemic stroke (AIS) and bilateral cerebral arteriopathies. Retrospective review of clinical features, course, and outcome. Neuroimaging was analyzed for infarct pattern, cerebrovascular diagnosis (anatomic/Childhood Arterial Ischemic Stroke Standardized Classification and Diagnostic Evaluation [CASCADE] criteria), and disease progression. In the 31 children (median age, 18 months), presentations included acute hemiparesis (n=23) and focal seizures (n=12). Seven had systemic arterial disease; 13 had cardiac abnormalities. Twenty had recurrent AIS or transient ischemic attack (after median of 3 months); 16 had >1 recurrence. Median modified Rankin Scale score was 3, with motor impairments in 20, cognitive impairments in 11, and seizures in 7. At presentation, 17 had old and acute infarcts. Twenty-five had high signal in white matter. A total of 13/23 reimaged patients accrued further infarcts over a median of 39 months. Arteriopathy involved the carotid circulation bilaterally in all; 6 had posterior circulation and 11 had extracranial involvement. Arteriopathy distribution was symmetric in 24/31. CASCADE categories were 3A in 19, 3B in 5, 3C in 5, and 7 in 2. After a ...Continue Reading
