Abstract

Twin-to-twin transfusion syndrome (TTTS) is a serious complication typical of monochorionic pregnancies. Cases in dichorionic pregnancies have been described. The authors present a case report of a presumed TTTS in a dichorionic pregnancy followed at our institution in which the patient presented to the emergency department at 31 4/7 weeks’ gestation complaining of lack of fetal movements. Both fetuses did not show any cardiac activity. On the first twin, an oligohydramnios was present and his bladder was not visualised and, on the second twin, a polyhydramnios and an augmented bladder were visualised. Pathological findings of the fetuses were compatible with a diagnosis of TTTS and placental study confirmed the presence of a dichorionic/diamniotic placenta, with superficial vessels crossing the dividing membrane.
