Abstract：
Twin-twin transfusion syndrome occurs in multiple gestations and involves a chronic flow of blood from one twin to another twin and is a rare entity. We present a case of 32-years-old primigravida with a twin pregnancy who presented with increasing abdominal girth inappropriate with her gestational age at 21 weeks of her pregnancy. Ultrasound findings were suggestive of twin-twin transfusion syndrome. The patient was provided with treatment options but due to polyhydramnios and short cervix, the patient went into spontaneous labour the same day with a poor pregnancy outcome. Twin-twin transfusion syndrome leads to a high rate of perinatal morbidity due to its poorly understood aetiology and difficulty in diagnosing and treatment. Early diagnosis during antenatal ultrasound is important in reducing morbidity and mortality rates.

摘要：
双胎输血综合征发生在多个妊娠中，涉及血液从一个双胞胎到另一个双胞胎的慢性流动，是一种罕见的实体。我们介绍了一例32岁的primigravida，患有双胎妊娠，在怀孕21周时腹部围长不适合她的胎龄。超声检查结果提示双胎输血综合征。患者接受了治疗选择，但由于羊水过多和子宫颈短小，患者当天自然分娩，妊娠结局不佳。双胎输血综合征由于其病因了解甚少，诊断和治疗困难，导致围产期发病率高。产前超声检查期间的早期诊断对于降低发病率和死亡率很重要。
