"In the normal situation, the right umbilical vein begins to obliterate in the ~4th week of gestation and disappears by the 7th week. With a PRUV, the right umbilical vein remains open and the left umbilical vein usually obliterates. A PRUV may also be supernumerary 6."

"A PRUV can be intra- or extrahepatic. The former is much commoner."
"It is usually detected in the 2nd to 3rd trimester. Assessment is usually made in the axial plane and colour Doppler is often required. An intrahepatic persistent right umbilical vein may be seen as an umbilical vein abnormally connected to the right portal vein and the fetal gallbladder is positioned medial to the PRUV."
"When additional anomalies are ruled out, a PRUV in isolation carries a generally favourable outcome 1,9."
