Abnormal number of vessels. 2-vessels cords. Single umbilical artery (SUA), the most common anatomical abnormality of the umbilical cord, is found in 0,2-1,1% of singleton pregnancies1, and in 6-11% of multiple pregnancies. The selection process of the missing (or existing) vessel is likely to be random, even though a right single artery is slightly more common2.
The umbilical cord is made up of three blood vessels: two smaller arteries which carry blood to the placenta and a larger vein which returns blood to the fetus. It can grow to be 60 cm long, allowing the baby enough cord to safely move around without causing damage to the cord or the placenta.
