胎儿脐带缠绕的超声诊断价值

The Value of Ultrasonography in the Diagnosis of Fetal Umbilical Cord Entanglement

目的探讨超声诊断胎儿脐带缠绕的临床价值。方法对98例晚期妊娠孕妇进行超声检查,观察胎儿颈后、躯干、四肢皮肤和软组织有无压迹,脐血管回声及脐带拉直征等;彩色多普勒探察压迹处有无脐带彩色血流信号,周围有无血流环绕。结果98例胎儿中,脐带缠绕55例:单纯脐带绕颈者45例,其中绕1周者40例,绕2周者4例,绕3周者1例;单纯腹部缠绕8例,其中绕1周者5例,绕2周者2例,绕3周者1例;脐带绕颈2周合并腹部缠绕2周者1例;肢体缠绕1例。超声诊断与产后符合率为96.5%。结论超声诊断脐带缠绕具有非损伤性、可重复操作、快捷准确的特点,为临床观察产程、选择生产方式和时机提供最佳依据。

Objective To investigate the clinical value of ultrasonography in diagnosing fetal umbilical cord entanglement. Methods From the ultrasound results of 98 pregnant women in the third trimester,to inspect the skin and soft tissue impression of posterior of neck, trunk and climbs, echo of cord vessel, abnormality of umbilical cord and so on. Results 55 cases fetals showed cord entanglement,inconcluding 45 cases with simple cord around neck,8 cases belong tosimple cord around abdomen,1 case cord entanglement com- bine neck with abdomen, 1 case cord around climbs. The rate of operational and diagnosed accurately by ultrasonography was 96.5 %. Conclusion Ultrasonography can be the first auxiliary method to check umbilical cord entanglement. It has important elinineal value.
