Pediatrics 35 years experience
Single artery: Usually in the umbilical cord there are two arteries and one vein. Every now and then a baby is born with one artery in the umbilical cord. In the majority of cases this is not a problem. That single artery can support the pregnancy. Occasionally the single artery can indicate the presence of a congenital abnormality of heart, kidney, intestines. This can be identified by ultrasound.

Majority no problem: Usually the cord has 2 arteries and a vein. It is found in about 5% of pregnancies. The vast majority have no problems at birth, however in about a fourth of these kids there is a higher incidence of malformations that could be in the GI tract, the heart or the nervous system. Also it is associated with higher incidence of chromosomal anomalies like trisomy 18 or trisomy 13.

Usually none.: Single umbilical artery is rarely associated with genetic syndromes such as trisomy 18 (edwards' syndrome), in which case it has long-term effects. 99% of the time it is a benign variant of the umbilical anatomy without any long-term consequence.

Baby only needs one.As long as it provided the nutrients baby needed to develop/grow it has done the only job it has. Either the one or two wither and disappear after birth.
