摘　　要：目的 :探讨子宫动脉与静脉导管多普勒血流频谱在胎儿生长受限(FGR)中的应用价值。方法 :选择26例确诊为FGR的孕妇为观察组,另外选择同一时期胎儿生长正常的26例孕妇为对照组,2组均行子宫动脉和静脉导管超声检测,比较2组子宫动脉相关血流指标、静脉导管频谱、胎儿出生时孕周及体质量。结果:观察组子宫动脉PI、RI、收缩期血流速度/舒张期血流速度(S/D)平均值、舒张早期切迹发生率均高于对照组(均P<0.05);观察组胎儿静脉导管分流率增加,且出现心房收缩谷(A谷)消失和反流的例数显著高于对照组(均P<0.05);对照组胎儿出生时孕周和体质量均高于观察组(均P<0.05)。结论:彩色多普勒超声检测子宫动脉和静脉导管血流频谱可早期反映胎儿血流循环异常情况,发现FGR,为临床提供影像学依据,及时采取相关措施,避免发生早产等情况。Objective:To explore the value of Doppler flow spectrum of uterine artery and ductus venous in fetal growth restriction(FGR).Methods:26 cases of pregnant women diagnosed as FGR were selected as the observation group.In addition,26 pregnant women with normal fetal growth in the same period of time were selected as the control group.The two groups of pregnant women were examined by ultrasound of uterine artery and ductus venous,the blood flow index of uterine artery and the frequency spectrum of ductus venous were compared between the two groups.And the gestational age and body mass of the fetus at birth were compared between the two groups.Results:The value of RI,PI,S/D and the incidence of early diastolic notch were higher in the observation group than those in the control group(all P<0.05).The ductus venous shunting ratio and the number of atrial contraction valley disappearance and shunting cases in the observation group were significantly higher than those in the control group(all P<0.05).And the gestational age and body mass of the fetus at birth in the control group were were significantly higher than those in the observation group(both P<0.05).Conclusions:The blood flow spectrum of uterine artery and ductus venous measured by color Doppler can reflect the difference of fetal blood circulation in early time under normal circumstances,FGR can be found as early as possible,which can provide imaging basis for doctors,so that they can take relevant measures in time to avoid premature delivery and other situations.
