目的探讨胎儿脐带缠绕肢体的彩超声像图表现及其对临床的研究价值。方法 500例孕妇行产前常规检查,对21例存在脐带缠绕肢体的超声声像图表现进行研究。结果彩超诊断胎儿脐带缠绕肢体的准确率99.6%,敏感率95.18%,特异性99.58%,且胎儿脐带缠绕肢体合并其他部位缠绕组胎儿的病死率、剖宫产率、胎儿宫内窘迫的发生率均明显高于单纯缠绕肢体组(P<0.05)。结论脐带缠绕肢体具有特征性超声声像图表现,可作为常规产前检查项目,对于早期诊断、确定胎儿的分娩方式、提高围产儿的出生质量有重要临床价值。
Objective To investigate the color ultrasonography of fetal umbilical cord entangled limbs and its clinical value. Methods 500 pregnant women underwent prenatal routine examinations, and 21 cases with umbilical cord entangled limbs were studied by ultrasonography. Results The diagnostic accuracy of color doppler ultrasonography was 99.6%, the sensitivity rate was 95.18% and the specificity was 99.58%. The fetal mortality, cesarean section rate and the incidence of fetal distress in fetus with umbilical cord entanglement and wounds in other areas were also significantly different Were significantly higher than the simple entangled limb group (P <0.05). Conclusion Umbilical cord entangling limbs have characteristic ultrasonography, which can be used as routine prenatal examination items. It has important clinical value for early diagnosis, determination of fetus’ delivery mode and improvement of birth quality.
