nuchal cord

Result : The relative factors were nuchal cord and oligohydramnios in 24 cases of PD .

结果：24例PD中最常见的相关因素为脐带绕颈和羊水过少。

With the development of the ultrasound technology , prenatal diagnosis rate of the nuchal cord is getting higher and higher .

近年来随着超声技术的发展，脐带绕颈产前诊断率呈明显上升趋势。

Fixed neck with cervical vertebral loop after operation . Assessing Effect of Nuchal Cord on Perinatal Infants

术后用颈椎围领固定。脐带绕颈对围产儿的影响

Objective : To determine the diagnosis , surveillance and delivery method for pregnancies with nuchal cord and cephalic presentation .

目的：探讨脐带绕颈的诊断，监护时机及分娩方式的选择。

Conclusions The diagnostic value of CDFI for nuchal cord correlates with the interval between the CDFI and delivery .

结论CDFI对脐带绕颈的诊断率与CDFI检查距分娩时间密切相关；

In nuchal cord group , the rate of fetal distress was 24.5 % , newborn asphyxia 10.2 % , fetal death 2.04 % .

脐带绕颈的胎儿窘迫率为24.5%，窒息率为10.20%，死胎率为2.04%。

The studies about nuchal cord and its perinatal outcome were a lots , however the exact perinatal effect of nuchal cord is still under debate .

有关脐带绕颈对围产儿结局影响的研究很多，也颇有争议。

Diagnostic Value of Color Doppler Flow Imaging for Detecting Nuchal Cord Conclusion It was safe , reliable and accurate to diagnose umbilical cord around the neck by CDFI .

结论彩色多普勒超声诊断胎儿脐带绕颈安全、可靠、准确性高，具有很高的临床价值。

Umbilical cord , velamentous insertion , vasa previa , true knot , nuchal cord , abdominal insertion , sigle umbilical artery , umbilical vein , cord mass , etc ;

脐带：帆样附着，前位血管，脐带真结，颈部脐带，腹部脐带附着，单只脐动脉，脐静脉，脐带肿块等；

By term delivery , the neonatal weight were significantly higher in the group of S / D ≤ 2.5 than in the group of S / D2.5.There is no significant difference of Doppler umbilical artery flow velocimetry between in nuchal cord group and in no nuchal cord group .

足月分娩，S/D≤2.5组新生儿出生体重明显比2.5组重（P0.01）。脐带绕颈与无绕颈的脐动脉血流参数无统计学差异。
