What does it mean when there is only one artery in the umbilical cord?
Having only one artery in the umbilical cord, called a single umbilical artery (SUA), shouldn’t affect their health.

What is vessel cord?
The umbilical cord is the connection between your baby and the placenta. A normal umbilical cord has two arteries and one vein. This is known as a three-vessel cord.
