Vascular anomalies of the umbilical cord. II. Perinatal and pediatric implications.
Among 62 cases with single umbilical artery and 305 with velamentous insertion of the umbilical cord, we found a high incidence of congenital malformations in both groups, highest in the SUA-group. No organ system seemed to be more affected than the others. In both groups there was a high incidence of both intrauterine hypoxia and perinatal mortality among single live births without malformations. When following up these children we found several cases of congenital malformations or diseases not detected at birth, especially among children with a low birthweight. Although the mean birthweight for both groups was low, the children seemed to attain a normal length and weight quite rapidly. Children born with intrauterine growth retardation represented an exception in this respect as they seemed to remain small during childhood.
