Twin to Twin Transfusion Syndrome (TTTS) is a serious condition that occurs in monozygotic twins sharing a single placenta (monochorionic twins). In TTTS, there is an imbalance in the blood flow between the twins through shared placental vessels, leading to one twin (the donor) becoming anemic and the other (the recipient) becoming polycythemic. This condition can lead to severe complications for both twins if left untreated.
