umbilical venous dilatation
Umbilical venous dilatation is a rare entity and often tends to occur as an isolated finding .
Dilatation of the umbilical vein can arise from a number of pathologies:
- umbilical venous varix (UVV): particularly if focal
- fetal hydrops: a focal dilatation due to an umbilical venous varix with an ensuing thrombosis can also give to fetal hydrops as a consequence .
Complications
- increased risk of umbilical venous thrombosis
Further work up
It is often recommended to follow-up these abnormalities to exclude hemodynamic deterioration or cardiac failure .
