Objective To determine whether fetuses with an isolated single umbilical artery (SUA) were associated with fetal growth. Methods Eighty singleton pregnancies with isolated SUAs diagnosed and delivered from January 2009 to December in our hospital were selected as experimental group. Multiple pregnancies, fetuses with other system malformation and abnormal placenta or amniotic fluid were excluded. For control group, 80 normal singleton pregnancies were searched and paired at a ratio of 1∶1 during the same period in the same hospital The study protocol was approved by the Ethical Review Board of Investigation in Human Being of West China Second University Hospital, Sichuan University. Informed consent was obtained from the parents of each participating neonate.. The statistical analysis was used in two groups collected by retrospective analysis. Results ①The accuracy of diagnose was 95.2% (80/84) in this study. ②There were no significant differences in age, pregnant, pregnancy, gestational diabetes mellitus(GDM) and gestational hypertension(GH) between two groups (P>0.05). ③No significant difference was observed in neonatal sex between the two groups(P>0.05). ④There were significant differences in birth weight and height between SUA group and control group(P<0.05). Conclusions Compared with the normal fetuses, the birth weight is lighter and the birth height is shorter in fetuses with an isolated SUA.
