What happens if the umbilical cord only has one artery?
Sometimes one of the arteries is missing, usually the left one. If your umbilical cord only has one artery, it increases your risk for fetal anomalies. Single umbilical artery risks. Single artery umbilical cord problems only happen in around 1% of pregnancies, although the risk increases to 5% for twin pregnancies.
How serious is single umbilical artery?
About 2 in 10 babies (20 percent) with a single umbilical artery have health problems, including heart, kidney or digestion problems and genetic conditions.
Can single umbilical artery cause Down syndrome?
Babies with single umbilical artery are a little more likely to have birth defects, particularly in the kidney and heart. In some cases, babies who have a single umbilical artery and a birth defect may be more likely to have a genetic condition (such as Down Syndrome).
How does SUA affect baby?
Birth Defects: Studies have found that there is a higher chance for other birth defects in a baby with SUA. This can include heart defects, kidney problems, spine defects, and other less common birth defects. Many of these birth defects can be seen by ultrasound, but not all birth defects can be found during pregnancy.
Is single umbilical artery curable?
A two-vessel cord is more common in twin pregnancies, or when the cord has inserted at the edge of the placenta. If there are no other problems, this is called an isolated single umbilical artery. Most babies can manage well with two vessels and don’t need any further investigation or treatment.
What anomaly is a single umbilical artery?

Such abnormalities include trisomy 18 and renal and cardiac anomalies. Children with dysmorphic features may have characteristic findings that aid in diagnosis.
Is SUA high risk pregnancy?
A significant association was observed between SUA and increased risk of intrauterine fetal death and early neonatal death, as well as low birth weight and preterm birth.
Do SUA babies come early?
An umbilical cord with a single umbilical artery is also called a “two vessel cord” since it contains just one artery and one vein. Some researchers think single umbilical artery (SUA) might be associated with slightly smaller babies or delivering a few days early.
Are SUA babies smaller?
At birth, infants with an SUA appeared smaller, but the difference disappeared thereafter. There were no consistent differences in neurodevelopment at birth, 4 months, 8 months, 1 year, 3 years, 4 years, and 7 years.
Is SUA considered high risk pregnancy?
Conclusion. A significant association was observed between SUA and increased risk of intrauterine fetal death and early neonatal death, as well as low birth weight and preterm birth. Obstetrical history of the mother like parity was identified as an important predictor of SUA.
How common is SUA in pregnancy?
The absence of one of the arteries is called single umbilical artery (SUA). It is one of the most common sonographic findings during pregnancy with an incidence range that goes from 0.5 to 6 percent in single pregnancies [1–3].
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.
