| Abstract: | Anomalies in the number of major blood vessels in the umbilical cord are well documented in man and have been associated with both placental abnormalities and congenital problems in the neonate. This paper describes 5 cases of anomalies in the number of umbilical arteries or veins within the equine umbilical cord at term. In 4 cases, the anomalies affected vessels in the amniotic part of the cord, and in one case, vessels in the allantoic part. In all the cases placental morphology was essentially normal and fetal health and post natal development were not compromised as a result of the unusual arrangement of blood vessels within the cord. |
