Case reports of transient single umbilical artery blood flow in monochorionic twins.
We report two cases of transient single umbilical artery (UA) blood flow in growth-discordant monochorionic twins. The interval of single UA was for one week in case 1 and for a few days in case 2. We speculate a cord factor such as length, twisting, and insertion site can be the etiology of this condition.
