Extra-abdominal umbilical vein varix in a newborn

Abstract

Umbilical vein varices are rare fetal anomalies typically found intra-abdominally and identified on ultrasound prior to birth. Intra-abdominal umbilical vein varices account for approximately 4% of umbilical cord abnormalities and are thought to be a developmental abnormality rather than a congenital malformation. The umbilical vein varix anomaly been shown to be associated with a higher incidence of adverse perinatal outcomes and there is evidence of a relationship between this and chromosomal abnormalities. There have been few case reports of extra-abdominal varices. This case reviews a multiparous Hispanic female who delivered a baby with an extra-abdominal umbilical vein varix who was admitted to the neonatal intensive care unit but had an uncomplicated hospital course. The report reviews strategies for antenatal testing and surveillance of identified varices.
