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 investigate the clinical significance of single umbilical artery by examining and tracking fetuses with single umbilical artery. Methods Totally 24018 fetuses with prenatal ultrasound were examined. The fetal system and the status of placental amniotic fluid were examined ultrasonically. The abdominal cord segment, free segment and placenta attachment were observed. Results Totally 47 fetuses with single umbilical artery were detected in 24018 fetuses, with a detection rate of 0.2%. There were 23 simple unilateral umbilical arteries and 24 other patients with structural abnormalities. Five unilateral umbilical artery fetal chromosome karyotype analysis, including 2 cases of chromosomal abnormalities, 3 cases showed no abnormalities. Conclusion Single umbilical artery is closely related to fetal congenital malformation. Single umbilical artery can be used as a soft marker of fetal congenital anomalies. Ultrasound doctors should pay attention to its importance.
