Discordant pH between two umbilical cord arteries at delivery for a foetus with undetected blood flow at a unilateral umbilical artery.

Focussing on the haemodynamics of the umbilical cord arteries, thrombosis of the unilateral artery could be considered to indicate the extreme condition of a discordant umbilical arterial blood flow since there is no blood flow in the unilateral artery at all. An umbilical cord blood gas analysis at delivery can help assess foetal acid-base physiology. This is the first case report to describe discordance in pH values between the two umbilical cord arteries based on an umbilical cord blood gas analysis performed at delivery.
