Maternal and Antenatal Complications in Pregnancies Complicated by Fetal Intra-Abdominal Umbilical Vein Varix

Background/Objectives: Prior research suggests that fetal intra-abdominal umbilical vein varix (FIUVV) is associated with an increased risk of structural anomalies, aneuploidy, and poor obstetrical outcomes such as growth restriction and demise. Data in prior studies, however, are limited. The aim of this study is to determine the natural progression of FIUVV and its association with maternal and antenatal complications.
