Arteriovenous malformationsArteriovenous malformationsCerebral arteriovenous malformations occur in about 1 in 100, 000 of the population They are the most common cerebrovascular lesions in children. AVMs are congenital lesions which occur as a result of a malfunction in the normal separation of arteries and veins during embryonic development. AVMs in the CNS are more common above the tentorium, particularly around the middle cerebral artery.

Page 45: Neurological Conditions and Diseases (During Development)

Arteriovenous malformationsArteriovenous malformationsThe majority of AVMs are asymptomatic. Often these malformations are only discovered incidentally, usually during treatment for an unrelated disorder.AVMs that are symptomatic usually present in AVMs that are symptomatic usually present in young adulthood; the average age of young adulthood; the average age of presentation in children is about 10 years of age.presentation in children is about 10 years of age.

Stroke is much less common in children than in adults. The estimated incidence of stroke in children is The estimated incidence of stroke in children is approximately 3 in every 100,000 childrenapproximately 3 in every 100,000 childrenStroke in children is more likely to occur in the presence of Stroke in children is more likely to occur in the presence of underlying diseases, such as metabolic disorders, underlying diseases, such as metabolic disorders, haematological disorders (particularly sickle cell anaemia), haematological disorders (particularly sickle cell anaemia), congenital cardiac disease and moyamoya diseasecongenital cardiac disease and moyamoya disease

Cerebrovascular Accident (stroke)Cerebrovascular Accident (stroke)General care of a child who has had a stroke includes maintaining normal temperature, ensuring adequate oxygenation and consideration of aspirin in ischaemic stroke In the case of moyamoya disease improvements to cerebral blood flow, as a result of intracranial internal carotid occlusion, can be made by performing vasoreconstructive surgery (bypass surgery).The outcome following stroke in children is variable but survival is thought to be better than in adults The survival rate following stroke in children has been estimated to be about 85 per cent
