What are the side effects to have a two vessel umbilical cord?

A two-vessel umbilical cord, which typically has one artery and one vein instead of the usual two arteries and one vein, can lead to several potential side effects. These may include restricted fetal growth, increased risk of congenital anomalies, and possible complications during delivery. Additionally, it may be associated with conditions like oligohydramniOS (low amniotic fluid) and placental insufficiency. Close monitoring during pregnancy is essential to manage any associated risks.
