[Giant congenital paravertebral arteriovenous fistulas in children].

Six cases of giant congenital paravertebral arteriovenous fistula in children are presented. In one case the fistula was jugulocarotid, in another case between the vertebral artery and jugular vein. Two were cases of fistulae in the lower thoracic region, and the last two were subclavian fistulae, one of which caused the death of the neonate. The principal embryologic and clinical features of these anomalies are described, and the choice between treatment by surgery or embolization discussed in the light of the new materials available for the latter procedure.
