[Vertebral arteriovenous fistula and neonatal cardiac insufficiency: diagnosis using duplex Doppler echography]

An extracranial arteriovenous fistula case, placed in vertebral artery territory that dealt with congestive heart failure and which developed advantageously without a surgical treatment is shown. Authors emphasize the fact of being a rarity the so premature beginning of the signs in a arteriovenous communication at that level, results in Doppler duplex echography and the need to have in count this entity previous to congestive heart failure with a deep origin in neonatal period.
