Prenatal diagnosis of a single umbilical artery should prompt examination for other anomalies. Because associated anomalies can occur in any organ system, consider a detailed anatomy survey whenever a 2-vessel cord is discovered.

The most common abnormality of the umbilical cord is a single umbilical artery (SUA), which occurs in 0.5% to 2.5% of pregnancies.[1] This finding is sometimes referred to as a 2-vessel cord. The loss of 1 umbilical artery likely occurs secondary to thrombotic atrophy of a previously normal artery.

I had a boy, and a 2 vessel cord.  I would not worry about it at all, the non-stress test can take some time, but you get to see your baby every week.  Basically they like to see the babies heartbeat go from one state to another and then back down, also to make sure that your fluid is normal.  We had them every...

My baby only had a 2 vessel cord, instead of the normal 3 vessel cord. It's not uncommon, but because my baby didn't get as much oxygen and blood flow as 3 vessel umbilical cord babies, my doctor wanted to be extra careful that my baby wasn't to stressed out.

A. There are two ways that folks look at a 2 vessel cord (or a "single umbilical artery", "SUA"). The first is that, IF you have a baby with many obvious malformations, it is common for that child ALSO to have a SUA.

Rare developmental changes which can occur to the embryonic umbilical cord are persistence of the right "vitelline" vein, creating a four-vessel cord with two arteries and two veins. The reverse of this is obliteration of an artery and vein and the development of ... Research indicates a 2% probability of this cord finding.
