目的:通过单脐动脉胎儿的产前发育情况及产后半年内的随访,了解单脐动脉对胎儿及新生儿的影响。方法:选取2009年3月～2011年3月天津市中心妇产科医院57例单脐动脉胎儿,综合分析产前超声、胎儿或新生儿的染色体检查、临床常规产检、产后脐带病理回报结果及对新生儿产后半年内的追访的结果。结果:在57例单脐动脉的病例中,合并其他系统胎儿发育异常者26例,取脐血行染色体检查异常的5例,产后追访发现3例单纯性单脐动脉胎儿合并微小畸形。结论:当产前超声检查中发现有单脐动脉时,应多方位、多角度观察胎儿及妊娠附属物,结合染色体检查早期发现胎儿异常,降低人口出生缺陷率,同时为临床监测孕产妇各项指标提供依据。
OBJECTIVE: To understand the effects of unilateral umbilical arteries on fetuses and newborns through prenatal development of single umbilical artery fetuses and follow-up within six months after giving birth. Methods: From March 2009 to March 2011, 57 cases of unilateral umbilical artery fetuses in Tianjin Central Obstetrics and Gynecology Hospital were enrolled. The results of prenatal ultrasound, chromosome examination of fetus or newborn, routine clinical examination and postpartum umbilical cord pathological findings The results of the follow-up of newborns within six months after delivery. Results: Totally, 57 cases of single umbilical artery were enrolled in this study. Among them, 26 cases were found to have abnormal fetal development in other systems, 5 cases were diagnosed as chromosomal abnormalities by umbilical cord blood collection, and 3 cases of simple unilateral umbilical artery fetus with small deformity were found after delivery. Conclusion: When there is a single umbilical artery in the prenatal ultrasound examination, the fetus and its appendages should be observed in different directions and angles. Combined with chromosomal abnormalities, fetal abnormalities can be detected early and the rate of birth defects can be reduced. At the same time, Indicators provide the basis.
