A consecutive series of 1,500 placentas has been examined with particular reference to the number of blood vessels in the umbilical cord. Complete absence of one umbilical artery occurred in 15 instances. In 7 infants there were some congenital abnormalities noted on examination; 3 were of major, character. One infant was stillborn. The anomaly occurred 3 times in one of twins. In a series of 100 twin placentas, one umbilical cord lacked one artery in 7 cases. The majority of these twins were monozygous. |
