AbstractIn this retrospective study, we reviewed the charts and collected clinical and radiographic data on children (age range, 1 month to 18 years) with symptoms and radiographic confirmation of ischemic stroke for the period of January 1996 to July 2006. Ninety-four children were enrolled. Eighty-eight had arterial ischemic stroke and six had sinovenous thrombosis. Twenty-nine percent of the children had seizures. Twenty-six percent had diffuse neurological signs and 76% had focal neurological signs. Risk factors included vascular disease (33%), infection (27%), metabolic disorders (18%), trauma (11%), prothrombotic states (13%), cardiac disease (10%), and mitochondrial disease (6%). Ten percent (n=9) had no identifiable cause. Twenty-two percent of the children had more than one risk factor. Anterior territory (70%) was more involved than posterior territory (18%) in arterial ischemic stroke. Unilateral infarctions were more common on the left side (51%) than on the right (24.5%). Neurological deficits were present in 45% (n=34/75) of the children; the most frequent deficit was motor impairment (24%). Seven children (9%) died in the acute stage. There were 12 children (16%) who had recurrent stroke and 8 children (8/12) who had underlying vascular disease. The vascular disease included moyamoya disease (5), CNS lupus (1) and ill-defined vasculopathy (2). The etiology pattern in Taiwan was different from that in Western countries. Vascular disease was a significant risk factor for recurrence in childhood ischemic stroke.
