Fetal intra-abdominal umbilical vein varix (FIUVV) is a focal aneurysmal dilatation of the umbilical vein. Its clinical importance has not yet been clearly established, but it has been reported to be associated with increased fetal death rate (in nearly 44% of cases) and chromosomal abnormalities (in 12% of cases). We report 2 cases of FIUVV diagnosed via sonography in the third trimester.
