[Cerebral arteriovenous fistula as a cause of neonatal cardiac insufficiency. Presentation of 3 cases].

The CAVF with aneurysm of the vein of Galen is an uncommon malformation, leading to the wrong diagnosis of congenital heart disease. We present the clinical and hemodynamic findings in three cases. Cranial echography has been useful as a noninvasive diagnostic tool. Surgical treatment can be difficult and the general outlook is poor.
