The Placenta in Twin-to-Twin Transfusion Syndrome and Twin Anemia Polycythemia Sequence

  • Isabel Couck (a1) (a2) and Liesbeth Lewi (a1) (a2)

Abstract

Twin-to-twin transfusion syndrome (TTTS) and twin anemia polycythemia sequence (TAPS) are complications unique to monochorionic twin pregnancies and their shared circulation. Both are the result of the transfusion imbalance in the intertwin circulation. TTTS is characterized by an amniotic fluid discordance, whereas in TAPS, there is a severe discordance in hemoglobin levels. The article gives an overview of the typical features of TTTS and TAPS placentas.
