    Abstract

    We present two cases of fetal intra-abdominal umbilical vein varix (FIUVV) assessed using Radiant Flow, HDlive Flow, and SlowflowHD. In the first case, FIUVV may have been caused by a persistent right umbilical vein, and it may have been due to umbilical ring contracture in the second case. These causes were suspected by the novel Doppler ultrasound. These novel Doppler techniques may provide useful information on the prenatal diagnosis and understanding of the pathophysiology of FIUVV.
