Prenatal diagnosis of intrahepatic arteriovenous shunts

Abstract

A case of mixed intrahepatic arteriovenous shunts in a fetus diagnosed at 35 weeks' gestation is presented. Color Doppler ultrasonography in the fetal liver demonstrated complicated vascular connections fed by the hepatic arterial branches and drained into the portal and middle hepatic veins. Pulsed Doppler ultrasonography identified a high cardiac output state by the detection of increased flow velocities of the great vessels. The contribution of Doppler ultrasonography to hemodynamic changes is highlighted. The management is briefly discussed.
