摘　　要：目的:探讨产前超声筛查胎儿单脐动脉声像图的特征及其临床意义。方法:选择2007年12月—2009年7月于天津市中心妇产科医院进行产前超声检查的38 215例患者,发现单脐动脉366例,其中经分娩或引产证实的40例住院患者获得全部胎儿单脐动脉的临床和超声资料。结果:胎儿单脐动脉检出率约0.96%(366/38 215),40例超声均诊断为胎儿单脐动脉,超声显示在胎儿盆腔膀胱及脐轮斜切面仅见膀胱一侧脐动脉走行。其中,超声发现合并胎儿其他系统发育异常5例而引产,因宫内死胎引产1例;继续妊娠并生产的34例中,有12例在妊娠期间和产程中出现异常,7例胎儿发现异常。结论:彩色多普勒超声检查能准确诊断胎儿单脐动脉,超声检查发现胎儿单脐动脉时需多角度动态观察以明确是否合并其他器官发育畸形,对于继续妊娠者需密切注意胎儿发育情况和产程。Objective：To evaluate the clinical role and the ultrasonographic features in prenatal diagnosis of single umbilical artery（SUA） in Tianjin.Methods：To review 40 fetuses with SUA found in our hospital from December 2007 to July 2009 in Tianjin.Their clinical manifestation and pregnancy outcome were followed up.Results：In 40 cases,only single umbilical artery could be detected by ultrasonography.Among them,5 cases combined with other abnormalities by ultrasonography,1 case was induced of labor because of intrauterine fetal death.In the cases going on with their pregnancy,12 cases had disorders during the pregnancy course or the labor,7 cases were found to be combined with other abnormalities.Conclusions：Ultrasound-Doppler can diagnose the SUA correctly.When we find a fetus with SUA,we should analyze it from different aspect to except other organic malformations.To the cases going on with their pregnancy,we must pay more attention to the fetuses growth and delivery.
