Two Vessel Umbilical Cord (SUA)
By Carolyn M. Salafia, MD
Q. During an ultrasound, the doctor said I had a 2 vessel cord and that it can sometimes mean that there is a chance for a heart defect. What are the complications, if any, or things that can happen with this?
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.
HOWEVER, the majority of children with SUA have no other abnormalities.
