摘要
【目的】评价产前超声诊断胎儿单脐动脉的临床价值。【方法】产前应用彩色多普勒超声检查242例胎儿脐带,并进行胎儿畸形检查,与尸体解剖或产后追踪结果对照。【结果】共检出单脐动脉胎儿22例,其中合并先天性畸形12例,并有1例诊断为Holt Oram综合征。单脐动脉胎儿结束妊娠平均孕周数小于正常胎儿,单脐动脉胎儿平均体重比正常胎儿明显降低。【结论】单脐动脉与先天性畸形、遗传性疾病等密切相关,产前超声检查单脐动脉对降低围生期病死率、提高胎儿生存质量具有重要意义。
【Objective】To detect the single umbilical artery（SUA） by antenatal sonographic diagnosis,and compare the clinical significance of this soft marker with the postnatal outcome or autopsy.【Methods】Two hundred forty two fetuses were performed ultrasounic examination.The number of vessels in the umbilical cord was determined during the first visit and all the 242 fetuses were performed detail echocardiography and detection of other abnormalities.Fetal biometric assessment was done,and the predicted age was calculated.All cases of sonographically detected SUA were confirmed by examination of the umbilical cord after delivery or at autopsy.【Results】Twenty two fetuses of SUA were detected antenatally,12 cases of them with congenital abnormality including one case with Holt Oram syndrome.The SUA cases were significantly and more likely to be lighter and to be born at earlier gestations than the normal cases.【Conclusion】The presence of a single umbilical artery is recognised as a soft marker for congenital anomalies,with aneuploidy,earlier delivery and low birth weight.Recognising the importance of this soft tissue marker in counselling and management of pregnancies may provide the stimulus to improve detection rates.
