title: [Prognostic value of a single umbilical artery. 87 cases].
abstract: OBJECTIVE
  To study the effect of a single umbilical artery on infant prognosis.
  
  
  METHODS
  Unicentric retrospective case-control study based on 18,425 births and semi-late pregnancy interruptions.
  
  
  RESULTS
  There were 87 cases of single umbilical artery, frequently associated with a familial history of malformation in the sibhood (6.8%), gravid pathology (hypertension 11.5%, diabetes 6.8%), funicular anomaly (32%). One or several malformations were seen in 21% of the infants, the main cause of infant mortality (9%) and morbidity. The case-control study demonstrated that single umbilical artery corresponded to a moderate reduction in weight (-310 g), term (-1.4 weeks gestation), AGPAR scor at 1 and 5 minutes (-0.7) which was not significant when single umbilical artery was the sole pathology.
  
  
  CONCLUSIONS
  When occurring alone, single umbilical artery has little effect on infant prognosis which is more dependant on associated malformations and gravid pathologies determining antenatal and postnatal management.
