【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。
[Abstract]:Objective to investigate the diagnostic value of three-dimensional ultrasound in monochorionic monoamnionic twin pregnancy umbilical cord. 65 cases of monochorionic method for prenatal ultrasound examination of the November 2013 to March 2016 monoamnionic twin pregnancy pregnant women, according to the structure of screening of prenatal ultrasound screening standards, with the use of continuous tracking method of two fetal umbilical cord were observed. For 3D imaging of suspicious, umbilical cord entanglement, record the gestational weeks, the fetus has no structural abnormalities, or be traced to birth abortion, the ultrasound findings, pregnancy outcomes were analyzed retrospectively. Results 4 cases of monochorionic monoamnionic twin pregnancies in ultrasound examination was found in the umbilical cord between the two a fetus, three-dimensional ultrasound can clearly display the 3 fetal 8 fetal umbilical cord of pregnant women.4 cases in intrauterine death, 5 fetal survival in 3 with different degrees of deformity. The umbilical cord entanglement of single chorionic amniotic membrane, twins and two fetuses poses great threat to intrauterine fetal safety. With the help of three-dimensional ultrasound, careful examination is helpful for timely detection and strict monitoring, so as to provide reference for clinical obstetric treatment.
