摘要
目的通过对单脐动脉(SUA)的产科临床病例进行分析,进一步提高临床对单脐动脉的诊断和处理水平。方法回顾分析在我院分娩并诊断的37例单脐动脉病例,在同期无妊娠合并症及并发症的足月单胎非单脐动脉病例中随机选取37例做对照,分析SUA的妊娠结局、产前超声检查、S/D比值变化及胎心电子监护情况。结果在15793次分娩中发现单脐动脉37例,发生率为0.23%。其中单纯性单脐动脉24例,发生率为64.86%;合并其他超声异常的单脐动脉13例,发生率35.14%。产前超声检查32例,诊断符合率90.62%;出生缺陷8例,发生率21.62%。FGR8例,发生率21.62%;产前诊断28例,染色体异常发生率为3.57%;早产4例,发生率12.5%;死胎3例,围产儿死亡率8.10%;单脐动脉的出生缺陷、FGR、胎儿窘迫、S/D比值异常升高发生率及胎心电子监护异常发生率明显高于非单脐动脉,差异有统计学意义(P<0.05),新生儿窒息及围产儿死亡发生率无明显统计学差异(P>0.05)。结论单脐动脉有较高的新生儿出生缺陷、FGR、胎儿窘迫、早产及围产儿死亡发生率。大部分单脐动脉胎儿结局良好,产前超声检查发现单脐动脉应仔细检查胎儿的各个系统有无形态、结构异常,对继续妊娠的病例应动态监测胎儿宫内发育情况,加强产前、产时的监测。
Objectives：To improve diagnosis and obstetric management of the single umbilical artery （ SUA） through the analysis of the clinical case in our hospital.Methods：We retrospectively reviewed the records of 37 fetuses with SUA from to,at the same time we selected 37 cases which pregnancy women had no complication during gestation and had a term delivery ,and fetus had no SUA .Therefore we compared two groups in final outcome,ultrasonographic examination,S/ D value and fetus heart rat.Results： Since there had been 15793 fetus born in our hospital in which 37 fetus with SUA were only identified in total.Among them are 24 simple SUA and others were complicated abnormal hyperacoustic.Of the total,32 cases had a hyperacoustic examination before delivery,and 28 cases did an antenatal diagnosis,in which 21.62% chromosome abnormalities were found.In fetal outcome ,37 cases included 8 birth defect ,4 immature labor,3 fetal death.There had been a higher incidence of birth defect,FGR,fetal distress、S/D value variety and fetal heart rate monitor in SUAs than control group （P〈0.05）.But neonatal asphyxia incidence and perinatal mortality rate had no statistical significance between two groups.Conclusions： Fetus with SUA get easily birth defect,FGR,fetal distress and perinatal death.But the majority of them had a better outcome.If SUA are identified through prenatal ultrasound examination,other abnormalities are found in organ structure and function.And once gestation is selected,we should monitor dynamically fetus growth in uteric and FHR in prenatal and intrapartum.
