摘　　要：目的通过对单脐动脉胎儿的检查与随访,探讨单脐动脉的临床意义。方法进行产前超声检查的胎儿24018例,超声检查胎儿各系统结构及胎盘羊水情况,观察脐带的腹腔段、游离段及胎盘附着部。结果 24018例胎儿中检出单脐动脉胎儿47例,检出率为0.2%,其中单纯的单脐动脉23例,合并其它系统结构畸形者24例。5例单脐动脉胎儿进行了染色体核型分析,其中2例有染色体异常,3例未见异常。结论单脐动脉与胎儿先天性畸形有密切关系,单脐动脉可做为胎儿先天异常的一个软标记,超声医生应重视其重要性。Objective： To study the clinical singnificance of single umbilical artery by following up the fetus with single umbilical artery. Methods： The 24 018 fetal structure and their placenta and amniotic fluid were observed by ultrasound. The abdomina part, the free part and the part stiking to placenta were examined. Results： 47 fetus with single umbilical artery were discovered from 24018 fe- tus and the rate was 0. 2%. Among the 47 fetus, there were 23 fetus with simple single umbilical artery and 24 fetus with structure abnormality of other system. The chromosomes of 5 fetus were examined. Among these, 2 fetus were abnormal and 3 normal. Conclusions： There were close connection between single umbilical artery and congenital abnormal. Single umbilical artery should be used as a soft marker and ultrasound doctors should pay attention to its importance.
