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.
双胎输血综合征（TTTS）是单绒毛膜双胎妊娠特有的一种严重并发症。双绒毛膜双胎妊娠的病例也有报道。作者报告了1例在我院随访的双绒毛膜双胎妊娠疑似TTTS病例，该患者在妊娠31 4/7周时因胎动减少就诊于急诊科。两个胎儿均未显示任何心脏活动。第一个胎儿羊水过少，膀胱未显示，第二个胎儿羊水过多且膀胱增大。胎儿的病理检查结果符合TTTS诊断，胎盘检查证实为双绒毛膜/双羊膜胎盘，有浅表血管穿过分隔膜。
