Abstract
Stroke in infants and children is a neurological emergency. Prompt diagnosis and treatment are essential to the prevention of further brain injury. There are three major categories of stroke - ischemic stroke, hemorrhagic stroke, and neonatal stroke. Arterial ischemic stroke is most commonly due to vasculopathy, thrombotic state, or metabolic disease. Vasculopathies include focal cerebral arteriopathy, arterial dissection, Moya moya syndrome, and genetic disorders causing vascular abnormalities. Thrombotic stroke is due to an underlying hypercoagulable state or thromboembolic disease. Metabolic diseases causing stroke include mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes, Fabry Disease, urea cycle disorders, and organic acidurias. Hemorrhagic stroke is almost always due to a pre-existing vascular malformation. Various diagnostic modalities are used to diagnose stroke. Computed tomography is rapid but exposes children to radiation. Magnetic resonance imaging is the modality of choice, though its use can be limited if sedation is required. Evaluation for underlying cause of stroke is guided by the stroke subtype, though in pediatric stroke, genetic causes of stroke should be carefully considered. Treatment of stroke is based largely upon adult practice, even though the etiology of stroke in childhood is not the same. Acute treatment is largely supportive and focused on secondary prevention. Multicenter studies of neonatal and childhood stroke are underway, and evidence-based diagnostic and treatment strategies are on the horizon. A comprehensive and systematic approach to pediatric stroke is a necessary component of pediatric intensive care.
