Info

Selected images from a routine anomaly scan at 20 weeks gestation shows 2 vessel umbilical cord with single umbilical artery. The diameter of the umbilical artery approaches the diameter of the umbilical vein. This was an isolated finding with rest of the anomaly scan being normal.
Case Discussion
Single umbilical artery as an isolated finding may not be associated with aneuploidy. However, it is associated with an increased incidence of intrauterine growth restriction 1,2.
