彩色多普勒超声对单脐动脉的诊断价值

The Value of Color Doppler Ultrasonography in Fetuses with Single Umbilical Artery

目的探讨彩色多普勒超声对单脐动脉(SUA)的诊断价值。方法回顾分析本院诊断的40例胎儿SUA的超声表现及相关临床情况。结果将二维超声与彩色多普勒结合使用,诊断SUA敏感性可达97.5%,漏诊1例,占2.5%。40例SUA胎儿合并其他畸形18例,占45%。28例SUA的胎儿继续妊娠分娩,出现胎儿宫内发育迟缓6例,占21.4%,早产4例,占14.3%,胎儿死亡3例,占10.7%。结论产前超声诊断胎儿单脐动脉具有重要价值。

Objective To investigate the diagnositic value of ultrasonography in fetuses with Single Um-bilical Altery (SUA).Method forty cases of SUA diagnosed in our hospital were retrospective analyed, including the sonographic findings and clinical outcome.Results Two-dimensional ultlasound combined with Color Dopple were be used,the sensitivity of detection SUA is up to 97.5 percent,missed two cases, accounting for 2.5 percent.Among the 40 cases with SUA,18cases complicated by other deformities were detected,asccounting for 45 percentage;28 cases continued to be gregnancy and were be deliveried;6 cases,21 .4 percent,suffered from IUGR;four cases,14.3 percent,were be premature deliveried;three fetal death cases,10.7 percent,occurred.Conclusions Prenatal ultrasonography is of great value for detecting SUA.
