[Congenital intrahepatic arterioportal fistula as a cause of necrotizing enteritis--Doppler sonographic and angiographic detection].

A case of congenital arterioportal fistulas in a girl of 4 months of age is presented. Clinical signs of necrotising enteritis developed due to portal hypertension. The diagnosis was established via Doppler-duplex ultrasound showing a pulse-synchronous bidirectional flow pattern in the portal vein and its major branches. The diagnosis was confirmed by angiography.
