Strokes in Thai children : etiology and outcome.

In Asian countries, specific etiology and outcome of stroke in children are rarely reported. During January 1979 to December 1997, 68 children with stroke, admitted to the Department of Pediatrics, Ramathibodi Hospital, Bangkok were reviewed for etiology and outcome; 38 patients (22 males) had ischemic stroke and 30 (20 males) had hemorrhagic stroke. Severe headache, vomiting, disturbance of consciousness and papilledema were prominent presentations of hemorrhagic stroke. Bleeding from vascular anomalies of the brain (AVM) was the most common etiology of hemorrhagic stroke while septic and non-septic emboli from congenital and acquired heart diseases were the most common cause of ischemic stroke. The mortality rate was 7% and 9% in hemorrhagic and ischemic strokes, respectively. Complete recovery was observed in 52% of cases of hemorrhagic stroke but in only 26% of ischemic stroke. Hemiparesis was the most common residual neurological deficit with higher occurrence in ischemic stroke.
