Strokes in children: a medical center-based study.
Stroke is an important cause of mortality and morbidity in children. Cases of pediatric stroke admitted to National Taiwan University Hospital from January 1985 to December 1995 were reviewed. Patients whose stroke was obviously caused by premature birth, birth trauma or head injury were excluded. Totally 65 patients were enrolled, including 37 boys and 28 girls. Their ages ranged from birth to 18 years old. They were classified into two groups: ischemic stroke (38 patients) and hemorrhagic stroke (27 patients), according to the pathogenesis. The ages of onset, clinical manifestation, underlying diseases and treatment of these two groups were systematically analyzed. The major presenting symptoms of both ischemic and hemorrhagic strokes were motor deficit (65.8%) and consciousness disturbance (55.6%). A wide variety of diseases predisposing to strokes was identified. The major causes of hemorrhagic stroke were vascular malformation and oncologic conditions, with the latter, the most frequently encountered underlying diseases associated with childhood ischemic stroke. The mortality rate for hemorrhagic stroke was 37% and, for ischemic stroke, 21.1%. There was male predominance in pediatric stroke. Although the clinical symptoms and signs might provide some guidelines to differentiate between hemorrhagic and ischemic strokes, neuroimaging studies were crucial to more exact diagnosis. A variety of diseases may contribute to pediatric stroke. Early diagnosis determine treatability, then aggressive treatment are important.
