Abstract
The correlation of single artery umbilical cords with congenital anomalies is explored in the present study of 4808 consecutive deliveries. There were 38 single artery cords, and 6 of these were associated with additional fetal abnormalities. An attempt is made to present the correlation in a true perspective by adding these data to other similar studies. Acknowledgment is given to the many retrospective studies, but consecutive delivery series show that a single artery cord is of importance as an abnormal physical finding but not as a screening test to detect occult malformations.
