Twin anemia polycythemia sequence (TAPS) complicates up to 6 % of monochorionic (MC) diamniotic twin pregnancies typically in the late second or third trimester. Few and very small arterio-venous (AV) vascular anastomoses are the underlying angioarchitecture at the chorionic plate related to TAPS. However, in monoamniotic (MA) twins usually thick vascular anastomoses can be seen at the placental vascular equator and, therefore, one would not expect the development of TAPS in monoamniotic twins. We report a case of TAPS in a monoamniotic (MA) pregnancy at 26+5 weeks which favorably responded to fetoscopic laser coagulation of the small placental anastomoses, resolving both, severe anemia in one twin and polycythemia in the other one. The pregnancy could be prolonged until 32+5 weeks, when tightening cord entanglement with increasing umbilical resistance and umbilical post-systolic notches in one of the twins, indicated the need for delivery by cesarean section. There was only a moderate difference in neonatal hemoglobin concentrations, with the former polyglobulic twin needing a single partial volume exchange transfusion. Furthermore, the postnatal course of the babies was uneventful, according to their gestational age at birth. To our knowledge this is the first case report describing successful laser therapy for TAPS in monoamniotic twins.
