Cerebral arteriovenous malformations in children. Clinical features and outcome of treatment in children and in adults.
A study of 19 children with cerebral arteriovenous malformation (AVM) is reported; these children represent 12% of 161 patients with this disease at the Rome University Institute of Neurosurgery. The published data on intracranial arteriovenous malformations in children and in adults are reviewed and the clinical features and results of treatment in the two age groups compared. The results of surgical removal seem to be better in children while the follow-up mortality with conservative treatment is higher. The last point receives indirect confirmation from a study of the risk of bleeding in which the patients of our series were compared by age at clinical onset, viz. those under 15 years of age and those over 15 years. After an average follow-up of slightly over 10 years, the risk of bleeding is higher with onset before the age 15 years and significantly higher if the onset is nonhemorrhagic.
