Abstract We aimed to evaluate perinatal outcomes and blood gas indices of isolated single umbilical artery (SUA). In this retrospective study, 134 fetuses with SUA were evaluated. A total of 77 (57.4%) fetuses with isolated SUA (iSUA) were compared with maternal age-matched 95 fetuses with double umbilical arteries (DUA), with respect to pregnancy outcome and umbilical cord blood gas indices. The incidence of SUA in our cohort was 1.04%. Patients with iSUA had lower neonatal birth weight compared with the control group (2,635 ± 972 g vs 2,991 ± 669 g; p = 0.009). Small for gestational age (SGA) frequency was higher in the group of iSUA when compared with fetuses with DUA (17.4% vs 5.4%; p = 0.03). Regarding the umbilical cord blood gas, the parameters were comparable between the two groups. SUA has a favourable obstetric outcome as long as the accompanying malformations are ruled out. Furthermore, neonatal cord blood gas parameters in fetuses with iSUA do not differ from fetuses with DUA.
摘要 我们旨在评估孤立性单脐动脉（SUA）的围产期结局和血气指标。在这项回顾性研究中，对134例患有SUA的胎儿进行了评估。将总共77例（57.4%）孤立性SUA（iSUA）胎儿与95例年龄匹配的双脐动脉（DUA）胎儿在妊娠结局和脐血气指标方面进行了比较。我们队列中SUA的发生率为1.04%。与对照组相比，iSUA患者的新生儿出生体重较低（2635±972克 vs 2991±669克；p = 0.009）。与DUA胎儿相比，iSUA组小于胎龄儿（SGA）的发生率更高（17.4% vs 5.4%；p = 0.03）。关于脐血气，两组之间的参数具有可比性。只要排除伴随的畸形，SUA具有良好的产科结局。此外，iSUA胎儿的新生儿脐血气参数与DUA胎儿无异。
