摘要
目的报告12例联体双胎的超声特征。方法回顾性分析2003-2008年我科诊断并经病理证实的12例联体双胎。结果12例中对称性联体双胎10例,其中胸腹部联体5例,头部联体3例,侧面联体1例,骶尾部联体1例;不对称性联体双胎(寄生胎)2例;女7例,男2例,性别不明3例;脐血管数目异常8例。胸腹部联体超声特征大体相近;头部联体表现多样;寄生胎较为特殊。结论产前超声检查能为联体双胎的诊断提供重要信息;不同类型联体双胎的超声特征有助于提高诊断水平。
Objective To investigate prenatal sonographic features of 12 conjoined twins. Methods A retrospective analysis was made in 12 conjoined twins diagnosed with prenatal ultrasonography. All the cases were confirmed by following-up or autopsy. Results In 12 conjoined twins, 10 were symmetry conjoined twins, including 5 thorax-omphalopagus, 3 cephalopagus, 1 parapagus and 1 pyopagus; the other 2 cases were asymmetry conjoined twins parasitus. Seven cases were female and 2 were male, the rest 3 remained unclear of sexuality. Eight cases had abnormal number umbilical vessels. The ultra sonographic characteristics were similar in thorax-omphalopagus, but various in cephalopagus and special in 2 parasitus. Conclusion Prenatal ultrasonography can provide important information for diagnosis of conjoined twins. Ultrasonographic characteristics of different conjoined twins are useful to improve the diagnosis level.
