Arteriovenous malformations of the spinal cord in children.

Spinal arterivenous malformations occur in the pediatric age range more commonly than previously acknowledged. An analysis of 64 cases with onset under 18 years of age demonstrates pain to be the most common first symptom. A long delay to diagnosis permits development of significant paresis or plegia in the majority. Correctly performed myelography (with supine views) provided the diagnosis in 60%. A radical microsurgical excision appears to offer the best long-term results.
