Persistent Extrahepatic Right Umbilical Vein

Abstract

Persistent right umbilical vein (PRUV) is a vascular pathology in which the left umbilical vein becomes occluded while the right umbilical vein persists and remains open. When observing fetal anatomy during a routine 18-week scan, it is important to notice the direction of the vasculature for possible fetal anomalies such as PRUV. In this case, a full detailed sonogram of the fetus was conducted and an extrahepatic PRUV was observed using 2D imaging and further confirmed using color Doppler to identify the type of PRUV. Following the identification of the PRUV, the fetus was thoroughly assessed for the possibility of other associated anomalies. Clearly, when an anomaly is observed, it is crucial to assess the fetus for associated congenital variances to identify risk and potential outcome.
