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 length of the umbilical cord is approximately equal to the crown-rump length of the fetus throughout pregnancy. The umbilical cord in a full term neonate is usually about 50 centimeters (20 in) long and about 2 centimeters (0.75 in) in diameter. This diameter decreases rapidly within the placenta.
