[Prognostic value of a single umbilical artery. 87 cases]
1Service de Gynécologie-Obstétrique, Centre Hospitalier Général, Roanne.
Summary
A single umbilical artery (SUA) has minimal impact on infant prognosis when isolated. Prognosis is primarily influenced by associated malformations and maternal health conditions, guiding management strategies.
Area of Science:
- Perinatal medicine
- Fetal development
- Neonatology
Context:
- Single umbilical artery (SUA) is a common umbilical cord anomaly.
- Its association with adverse infant outcomes requires further investigation.
- Understanding SUA's isolated impact is crucial for accurate risk assessment.
Purpose:
- To evaluate the effect of isolated single umbilical artery on infant prognosis.
- To identify factors influencing outcomes in infants with SUA.
- To differentiate the impact of SUA from associated pathologies.
Summary:
- A retrospective case-control study of 18,425 births identified 87 cases of SUA.
- SUA was frequently linked to familial malformations, maternal hypertension, diabetes, and cord anomalies.
- While SUA correlated with slight reductions in birth weight, gestational age, and Apgar scores, these were not significant when SUA was the sole anomaly.
Impact:
- Isolated SUA has a minor effect on infant prognosis.
- Associated congenital malformations and maternal pathologies significantly impact infant outcomes.
- Accurate antenatal and postnatal management depends on identifying these associated risks.
