摘要
目的探讨三维超声对单绒毛膜单羊膜囊双胎脐带缠绕的诊断价值。方法对2013年11月至2016年3月进行产前超声检查的65例单绒毛膜单羊膜囊双胎孕妇,按产前超声筛查规范要求进行结构筛查,采用连续追踪法对两个胎儿的脐带进行观察,对可疑脐带缠绕者进行脐带三维成像,记录孕周、胎儿有无结构畸形,追踪至胎儿出生或被引产,将超声发现、妊娠结局等进行回顾性分析。结果 4例单绒毛膜单羊膜囊双胎孕妇在超声检查中被发现两个胎儿之间存在脐带缠绕,三维超声能够清晰显示脐带缠绕的情况。4例孕妇的8个胎儿中的3个胎死宫内,存活的5个胎儿中的3个合并不同程度的结构畸形。结论单绒毛膜单羊膜囊双胎两个胎儿的脐带相互缠绕对胎儿宫内安危造成很大威胁,借助三维超声细致检查有助于及时发现并给予严密监护,为临床产科处理提供参考意见。
Objective To discuss the diagnostic value of 3D-ultrasound for cord entanglement in monoamniotic twins. Methods From November 2013 to March 2016, a total of 65 monoamniotic twinsunderwent routine obstetric ultrasonography to screen fetal abnormalities in our hospital. The cord was meticulously observedusing a systematic continuous sequence approach. Fetuses who showed cord entanglement by 2-D ultrasound or 3-D flow Doppler were all recruited. The gestational weeks, fetal malformation, ultrasonic image feature of cord entangle- ment, and clinicaloutcome were recorded and analyzed retrospectively. Results 4 monoamniotic twins showed cord entanglement. Three-dimensional color Doppler clearly delineated thefeatures of entanglement. At following-up of 8 fetuses, 3 fetuses were found intrauterine fetal death and 3 fetuses with structural abnormalities except for 2 well infants.Conclusion Cord entanglement may threaten the safety of fetusesin monoamniotic pregnancies.In aid of 2-D ultrasound or 3-D flow Doppler in monoamniotic twins can help to find it in time, monitor it carefully and provide evidence for obstetric treatment.
