目的:分析彩色多普勒超声在胎儿脐带绕颈诊断中的效果。方法:选取我院2008年3月至2016年4月期间收治的240例孕周37~40周通过彩色多普勒超声诊断为脐带绕颈的产妇资料,对比分娩以后的最终结果。结果:通过分娩后证明脐带绕颈胎儿为237例,符合率为98.75%;当中18例脐动脉S/D值高于3,RI高于0.7,颈部脐带存在较深的压痕,提示胎儿存在宫内窘迫,并且通过剖宫产证实。结论:采用彩色多普勒超声进行胎儿脐带绕颈诊断具有极高的符合率,并且能够直观显示颈部血流与脐带缠绕状况,通过检测S/D与RI能够针对妊娠期宫内胎儿血供进行评价,能够为胎儿宫内窘迫提供相应的参考。
Objective: To analyze the effect of color Doppler ultrasound in the diagnosis of fetal cord around the neck. Methods: From March 2008 to April 2016 in our hospital from 240 cases of gestational weeks 37 to 40 weeks by color Doppler ultrasound diagnosis of umbilical cord around the neck maternal data, compared with the final result after delivery. Results: 237 cases of umbilical cord wound around the neck after delivery were found, the coincidence rate was 98.75%. Among them, the S / D values of 18 cases of umbilical arteries were higher than 3 and RI was higher than 0.7. There were deep indentations on the umbilical cord of the neck, Intrauterine distress exists and is confirmed by cesarean section. Conclusion: Color Doppler ultrasound fetal cord around the neck diagnosis with high coincidence rate, and can visually show the neck blood flow and umbilical cord entanglement, by detecting S / D and RI can be used for gestational intrauterine fetal blood supply For evaluation, can provide the appropriate reference for fetal distress.
