摘要
目的:探讨产前彩超检查在孕22-24周之间脐带异常附着诊断中的应用价值。方法:选取2020年9月-2021年9月于我院就诊的疑似胎儿脐带异常附着的53例产妇作为研究对象,均在孕22-24周之间接受彩超检查,将妊娠结局作为金标准,回顾性分析产前孕22-24周之间彩超检查的诊断结果,计算孕22-24周之间彩超检查诊断脐带异常附着的准确度、敏感度、特异度,并行Kappa检验进行一致性系数分析,计算彩超检查与金标准结果之间的一致性Kappa值。结果:彩超检查结果显示,53例疑似胎儿脐带异常附着的产妇中球拍状附着37例,帆状附着16例。经最终妊娠结局证实,53例疑似胎儿脐带异常附着的产妇中确诊45例,其中球拍状附着32例,帆状附着13例。临床上合并宫内发育迟缓2例,均为帆状附着,孕妇均无特殊临床表现。以最终妊娠结局为金标准,彩超检查诊断脐带异常附着的灵敏度为97.83%,特异度为85.71%,准确度为96.22%,假阳性率为14.29%,假阴性率为2.17%,阳性预测值为97.83%,阴性预测值为85.71%,正确指数为0.84。经Kappa一致性检验分析,彩超与金标准结果之间的一致性Kappa值为0.83,一致性处于较高水平。结论:产前彩超检查在孕22-24周之间脐带异常附着诊断中的应用价值较高,可提高脐带异常附着的诊断准确率,减少漏诊、误诊发生,为临床诊断及后续治疗提供客观依据,显著改善妊娠结局及新生儿结局,保障产妇及胎儿的生命安全。
Objective:To explore the application value of prenatal color Doppler ultrasonography in the diagnosis of abnormal umbilical cord adhesion between 22 and 24 weeks of pregnancy.Methods:53 pregnant women with suspected abnormal fetal umbilical cord attachment treated in our hospital from September 2020 to September 2021 were selected as the research objects.They all underwent color Doppler ultrasonography between 22 and 24 weeks of gestation.The pregnancy outcome was taken as the gold standard.The diagnostic results of color Doppler ultrasonography between 22 and 24 weeks of gestation were analyzed retrospectively,and the accuracy,sensitivity and accuracy of color Doppler ultrasonography in the diagnosis of abnormal umbilical cord attachment between 22 and 24 weeks of gestation were calculated Specificity,the consistency coefficient was analyzed by parallel Kappa test,and the consistency Kappa value between color Doppler ultrasound and gold standard results was calculated.Results:The results of color Doppler ultrasound showed that 37 cases of racket like attachment and 16 cases of sail like attachment were suspected of abnormal attachment of fetal umbilical cord.The final pregnancy outcome confirmed that 45 of 53 pregnant women suspected of abnormal fetal umbilical cord attachment were diagnosed,including 32 cases of racket attachment and 13 cases of sail attachment.Clinically,there were 2 cases of intrauterine growth retardation,all of which were sail like attachment,and there were no special clinical manifestations in pregnant women.Taking the final pregnancy outcome as the gold standard and the final pregnancy outcome as the gold standard,the sensitivity,specificity,accuracy,false positive rate,false negative rate,positive predictive value,negative predictive value and accuracy of color Doppler ultrasonography in the diagnosis of abnormal umbilical cord attachment were 97.83%,85.71%,96.22%,14.29%,2.17%,97.83%,85.71%and 0.84 respectively.By Kappa consistency test analysis,the Kappa value of consistency between col
