Confusing question: You ? Had a sua or the baby ? This is a variable finding that most often turns out to be an innocent incidental finding.A subgroup of patients will have chromosome defects or genetic syndromes, with other obvious anomalies. If this has not affected you so far, i would not expect any issues with the baby.Consult a geneticist affiliated with a children's hospital or medical school to gain more info. ...Read more

Did a SUA (single umbilical artery) cause my baby to die?

Did a SUA (single umbilical artery) cause my baby to die?

Doubtful: Many infants are born with a single umbilical artery and have an uncomplicated life. For some, it is just one of many abnormalities that are part of a complex pattern or syndrome, and could be part of a chromosome defect. I encourage parents to have a full workup done on infant deaths so they can understand what happened, and any implications for future pregnancies. ...Read more
