Description

Cerebrovascular problems in childhood include diverse problems of vascular supply to the brain and occur with an overall frequency of from 5 to 8/100000 children/year. Signs and symptoms at manifestation are manifold. They depend not only on localization of the infarction but also on age at injury and specific risk factors. Acute arterial ischemic insult in neonates is oligosymptomatic (short-lasting seizures); hemiparesis is the most common symptom in children. Risk factors are multiple for both neonates and children, with more thromboembolic events in neonates and (infection-related) vasculopathies or cardiac problems in children. MRI (diffusion weighted) is the golden standard for diagnosis. In the absence of evidence for treatment in both groups, guidelines suggest use of platelet aggregation. There are some special indications for anticoagulation. Thrombolysis should be evaluated. Two-thirds of children and neonates face lifelong neurological and neuropsychological problems. Spinal artery ischemia presents with acute spinal symptoms, mostly paraplegia. Risk factors and prognosis are similar to cerebral insults. Sinus venous thromboses are significantly less common. Provoking factors in newborns are mainly neonatal problems, and in children infections, especially in the ENT region. For diagnosis the delta sign in CT is less sensitive than MR/MR venography. In the absence of any evidence, LMWH or heparinization for 3–6 months are recommended. Prognosis is better in children than in neonates. Deep vein thrombosis and/or young age worsen the outcome.
