[Intrahepatic arteriovenous fistula. Prenatal diagnosis, physiopathological study and neonatal management]l

A case of arteriovenous fistula of the liver diagnosed at 30 weeks of gestation is reported. The etiologies of an hypoechogenic structure in the fetal liver are discussed showing the contribution of pulsed wave Doppler and color Doppler to the diagnosis. The clinical evolution towards heart failure led us to examine the pathophysiology of such a lesion. The prenatal management of this arteriovenous malformation is exposed.
