What does a two-vessel cord indicate?
Most babies’ umbilical cords have three blood vessels: one vein, which brings nutrients from the placenta to baby, and two arteries that bring waste back to the placenta. But a two-vessel cord has just one vein and one artery — that’s why the condition is also referred to as having a single umbilical artery.
Should I worry about SUA?
Having only one artery in the umbilical cord, called a single umbilical artery (SUA), shouldn’t affect their health. Usually, an umbilical cord has two arteries, along with a single vein, making a total of three vessels. The vein carries oxygen and nutrients to your baby, and the arteries remove waste products.
Is SUA considered high risk pregnancy?
Pregnancy complications: Another concern with SUA is a possible chance for problems later in pregnancy, like slow fetal growth, preterm delivery, or stillbirth. However, not all studies agree that there is a higher risk for pregnancy complications. Your OB provider will routinely monitor the growth of the baby.
What is 3 vessel cord in ultrasound?

What Causes 2 vessel cord in pregnancy?

Can you see Down Syndrome on 20 week ultrasound?
A Detailed Anomaly Scan done at 20 weeks can only detect 50% of Down Syndrome cases. First Trimester Screening, using bloods and Nuchal Translucency measurement, done between 10-14 weeks, can detect 94% of cases and Non-invasive Prenatal Testing (NIPT) from 9 weeks can detect 99% of Down Syndrome cases.
