彩色多普勒超声成像诊断胎儿单脐动脉的价值

Diagnostic value of single umbilical artery of fetus with color Doppler flow imaging

目的:探讨彩色多普勒对胎儿单脐动脉的诊断价值。方法:应用彩色Dopp ler超声产前检查孕妇的胎儿脐带3 086例,观察脐动脉及脐静脉的排列走向,记录脐血管的数目、并测量脐动脉的血流速度及S/D比值。结果:产前超声诊断单脐动脉12例,8例均合并其他畸形,4例胎儿出生后未发现明显异常,全部病例均经引产后及出生后证实。结论:彩色多普勒超声产前能准确诊断单脐动脉,为诊断合并其他畸形提供有价值的信息。

Objectlve To investigate the diagnostic value of single umbilical artery of fetus with color Doppler flow imaging （CDFI）. Method Umbilical cords of 3 086 pregnant women were studied with CDFI. The spread and number of umbilical vascular were recorded, also S/D and RI of umbilical arteries＇ blood flow were measured. Results 12 cases of fetal with single umbilical artery diagnosed by ultrasound before birth and 8 cases combined with other abnormality, another 4 fetuses didn＇ t show evident abnormality after birth. All the cases were confirmed after childbirth.
