The presence of only a few and very small arteriovenous vascular anastomoses characterizes the underlying angioarchitecture at the chorionic plate in cases of <jats:styled-content style=\"fixed-case\">TAPS<\/jats:styled-content>. In monoamniotic twins, large vascular anastomoses can usually be seen at the placental vascular equator, and therefore one would not expect the development of <jats:styled-content style=\"fixed-case\">TAPS<\/jats:styled-content> in monoamniotic twins. We report a case of <jats:styled-content style=\"fixed-case\">TAPS<\/jats:styled-content> in a monoamniotic pregnancy at 26\u2009+\u20095 weeks' gestation which responded favorably to fetoscopic laser coagulation of the small placental anastomoses, resolving severe anemia in one twin and polycythemia in the other. The pregnancy continued until 32\u2009+\u20095 weeks, when worsening cord entanglement with increased resistance and the development of postsystolic notches in the umbilical artery of one twin prompted delivery by Cesarean section. There was only a moderate difference in neonatal hemoglobin concentrations, with the former polycythemic twin needing a single partial volume exchange transfusion. The postnatal course of the neonates was uneventful, according to their gestational age at birth. To our knowledge this is the first case report describing successful laser therapy for <jats:styled-content style=\"fixed-case\">TAPS<\/jats:styled-content> in monoamniotic twins.
