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.
Should I worry about single umbilical artery?
Your baby is likely to be fine. Having only one artery, called a single umbilical artery (SUA), shouldn’t affect his health. Usually, an umbilical cord has two arteries, along with a single vein. The vein carries oxygen and nutrients to your baby, and the arteries remove waste products.
Can single umbilical artery affect baby?
There are many babies that have a single umbilical artery that have healthy pregnancies and deliveries. However, some babies with a single artery are at increased risk for birth defects. Examples of birth defects that babies with a two-vessel diagnosis may have include: heart problems.
What is associated with single umbilical artery?
Single umbilical artery is associated with an increased incidence of structural and chromosomal anomalies and growth restriction.
Is SUA high risk?
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.
Can SUA cause preterm labor?
Neonates with SUA and iSUA had increased rates of prematurity, growth restriction and adverse neonatal outcomes1. Studies also indicated that risks of some adverse neonatal outcomes, such as low birth weight, preterm delivery and low Apgar score, were increased in cases with SUA13, 14.
Does SUA mean Down Syndrome?
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). Important: Single umbilical artery by itself is not considered a birth defect. All babies with single umbilical artery are at risk for not growing as well in the uterus.
Should I worry about 2 vessel cord?
How will my two-vessel umbilical cord affect my baby? In most cases, it won’t: The one artery just makes up for what the missing one would do. However, there’s a slight increase in risk of growth problems and a minimal increase in risk of stillbirth.
Can the baby pull the umbilical cord?
DO NOT try to pull it off, even if it is only hanging on by a thread. Watch the umbilical cord stump for infection. This does not occur often. But if it does, the infection can spread quickly.
Does SUA mean Down syndrome?
Is single umbilical artery genetic?
In a recent study, a single umbilical artery was detected in 2% of fetuses. Fetuses with a single umbilical artery had significantly more chromosomal (10.3%) and congenital anomalies (27%) than those with two umbilical arteries.
Is SUA considered high risk pregnancy?
Isolated SUA is a risk factor for adverse pregnancy outcome. There is an increased risk of intrauterine and intrapartum deaths among fetuses with SUA.
