Abstract：
In monochorionic twins with no evidence of chronic twin-to-twin transfusion syndrome or twin anemia-polycythemia sequence, a sudden onset of fetal transfusion syndrome after the second trimester of pregnancy is defined as acute twin-to-twin transfusion syndrome. Labor pain, change in the fetal position, and birth order are known risk factors for this condition, and the hemoglobin level of the donor twin is usually reported to be <12 g/dL. We report a recent case of acute twin-to-twin transfusion syndrome without effective labor pain causing cervical changes, resulting in fetal bradycardia and neonatal death after birth; however, the anemia of the donor twin was not as severe as has been reported previously in twin-to-twin transfusion syndrome cases.
摘要：
在没有慢性双胎对双胎输血综合征或双胎贫血-红细胞增多症序列证据的单绒毛膜双胞胎中，妊娠中期后突然发生的胎儿输血综合征被定义为急性双胎对双胎输血综合征.分娩疼痛，胎儿位置的改变,出生顺序是这种情况的已知危险因素，供体双胞胎的血红蛋白水平通常报告为<12g/dL。我们报告了最近的一例急性双胎对双胎输血综合征，没有引起宫颈变化的有效分娩疼痛，导致胎儿心动过缓和新生儿出生后死亡；然而，供体双胎的贫血没有先前报道的双胎对双胎输血综合征病例那么严重.
