Prenatal color and pulsed Doppler sonographic documentation of intrathoracic umbilical vein and ductus venosus, confirming extensive hepatic herniation in left congenital diaphragmatic hernia.

Prenatal sonographic diagnosis of an unusual case of a large left congenital diaphragmatic hernia is presented. The fetal stomach was located within the right thorax, posterior to the dextropositioned heart. Color and pulsed Doppler ultrasonography documented intrathoracic umbilical vein and ductus venosus vessels and respective waveforms, confirming extensive herniation of the left hepatic lobe.
