Diagnostic value and clinical significance of B-ultrasound examination in diagnosis of cord around neck

目的探讨B超检查对胎儿脐带绕颈的诊断价值及临床意义。方法对3650例37-42周足月妊娠孕妇进行常规B超检查，并对检查发现的脐带绕颈胎儿进行追踪分析。结果3650例足月妊娠胎儿中，B超诊断胎儿脐带绕颈1132例，娩出后证实1031例，脐带绕颈发生率26．63％，诊断符合率为91．08％。结论分娩前B超探测脐带绕颈准确率高，可作为临床医生选择适宜的分娩方式提供重要参考依据，并有助于降低围产儿死亡率。

Objective To study the diagnostic value and clinical significance of B-ultrasound examination in diagnosis of cord around neck. Methods From July 2004 to July 2006,3650 uterogestation gravidas were examined by B-ultrasound. Results 1132 cases of cord around neck were diagnosed by B-ultrasound examination prior to delivery, and 1031 cases were confirmed after parturition. The incidence rate of cord around neck was 26.63% and the diagnostic accuracy was 91. 08%. Conclusion The diagnostic accuracy of B-ultrasound examination is high prior to delivery. B- ultrasound examination can provide a reliable basis for clinicians to institute treatment plan and choose proper delivery style. It is thereupon helpful to reduce the perinatal mortality rate.
