Congenital arterio-venous fistulas (4 systemic extra-visceral fistulas).
Arterio-venous fistulas are rare in children but usually congenital. We report four cases which are very unusual because of their origin or their localization. We compiled a classification of congenital fistulas which is easily used and collected 582 cases of congenital arterio-venous fistulas from the literature.
