(A): Longitudinal plane of the fetal abdomen, color Doppler evaluation, showing the absence of ductus venosus and a wide umbilical shunt directed to the inferior vena cava. (B): 3D evaluation shows abnormal umbilical vein drainage into the inferior vena cava. (C): Pathological examination showing the drainage of the umbilical vein into the inferior vena cava. (D): Transverse view at the level of insertion of the umbilical cord showing the absence of the portal venous system and persistent small stomach (white arrow) UV—umbilical vein.
