双胎妊娠胎儿异常的产前超声特征

Prenatal ultrasonic features of twin pregnancy with fetal abnormalities

目的探讨产前超声诊断双胎妊娠胎儿异常的价值。方法回顾性分析14对双胎妊娠胎儿异常的产前声像图特征及临床资料。结果超声诊断5对为双胎之一结构畸形,1对为双胎均结构畸形,1对为双胎输血综合征,2对为选择性胎儿宫内发育迟缓,1对为双胎之一死亡后孪生胎神经系统损伤,2对为联体双胎,2对为双胎反向动脉灌注序列症。结论超声有助于诊断多种双胎妊娠并发症和畸形,有重要临床指导意义。

Objective To investigate the diagnostic value of ultrasound in twin pregnancy with fetal abnormalities. Meth- ods The ultrasonic features and clinical data of 14 twin pregnancies with fetal abnormalities found by prenatal ultrasound were analyzed retrospectively. Results Among 14 twin pregnancies, there were 5 twins with structurally anomalous in 1 fetus, 1 with structurally anomalous in both fetuses, 1 with twin-to-twin transfusion syndrome, 2 with selective intrauter- ine growth restriction, 1 with co-twin neurological abnormality following the death of 1 twin, 2 with conjoined twins, 2 with twin reverse arterial perfusion sequence. Conclusion Ultrasound can diagnose structural complications and abnormali- ties of twin pregnancy, and plays an important role in clinical treatment.
