Intracranial arteriovenous malformations in infancy and adolescence.
Fifteen children and adolescents with intracranial arteriovenous malformations are reviewed and their data analyzed; their ages varied between 1 day and 15 years and there was a slight predominance of males (9 male and 6 female patients). In this series, the arteriovenous malformations appeared clinically as cerebral hemorrhage in 9 cases, epilepsy in 3, mental retardation with epilepsy in 1, subarachnoid hemorrhage in 1, and cardiac insufficiency at birth in the other. The diagnostic procedures used were computerized transmission tomography (CTT) of the cerebrum in 14 cases, cerebral panarteriography in 15, and EEG in 4 cases. Treatment took the form of surgery, radiation therapy, or medication. The last was administered to patients with epilepsy, either as a complement to other modes of treatment or as the only treatment. In all, 4 cases died, 2 for reasons to do with their operations, 1 from a lesion of the brain stem in a hematoma of the cerebellum that had not been surgically treated, and the other from an intraventricular hemorrhage 4 months after surgery. In the last patient, necropsy revealed remnants of the arteriovenous malformation. The overall mortality was thus 26% and the surgical mortality, 12.6%. Of the 11 surviving patients only 3 received anticonvulsant drugs; each of them had a good I.Q. and good marks at school, as did the other 8 survivors.
