Ultrasonographic examination at 16 weeks 5 days' gestation diagnosed a monoamniotic triplet gestation complicated by thoracopagus conjoined twins. After pregnancy termination, the ultrasonographic diagnoses were confirmed by pathologic examination. In reporting the first ultrasonographically diagnosed monamniotic triplets with conjoined twins, we demonstrate that a systematic evaluation by twin-derived ultrasonographic techniques may permit correct diagnosis of unusual triplet pregnancies.
孕16周5天时的超声检查诊断为单羊膜囊三胎妊娠，合并胸腹联体双胎。终止妊娠后，病理检查证实了超声诊断结果。在报告首例超声诊断的单羊膜囊三胎联体双胎时，我们证明，采用双胎超声技术进行系统评估可正确诊断异常的三胎妊娠。
