The significance of assessing the umbilical cord on the placental side: A case report on fused umbilical arteries.

This report details the case of a fetus with fused umbilical arteries (FUAs), which exhibited the presence of a single umbilical artery near the site of placental insertion, as well as normal two umbilical arteries at the fetal end of the umbilical cord. In our case, as the pregnancy progressed, there was an occurrence of late-onset fetal growth restriction and oligohydramnios. This is a possibility that FUAs might impact the development of the fetus.
