摘要
目的应用彩色多普勒超声研究羊水过少的胎儿脐动脉(UA)及大脑中动脉(MCA)的血流动力学变化,了解两者间的关系及围生儿结局。方法应用彩色多普勒超声技术,对24例羊水过少胎儿脐动脉及大脑中动脉血流S/D值(收缩期/舒张期血流速度)、RI(阻力指数)、MCA与UA之间的RI比值进行分析,随访围生儿预后。结果胎儿脐动脉S/D值≥3及大脑中动脉S/D值≤4者在羊水过少组较对照组(正常组)明显增多(P<0.05),且该组胎儿易发生不良围生儿结局。结论产前检测胎儿脐动脉和大脑中动脉血流动力学指标,预测羊水过少胎儿宫内发育情况,评估围生儿预后,较单一血管血流动力学指标检测具有明显优势。
Objective Using colored Doppler ultrasonography we aimed to explore the hemodynamic changes in umbilical arteries (UA)and middle cerebral arteries (MCA)in oligohydramnios and then to show the correlation between such changes and perinatal outcomes.Methods The colored Doppler ultrasonography was applied to detect UA and MCA in 24 cases with oligohydramnios and to analyze the systolic /diastolic ratio (S/D),resistances index(RI) of the two arteries.A survey was followed on perinatal prognosis.Results It showed a significantly increase in S/D ratio (S/D≥3) in the UA and the S/D≤4 in the MCA in oligohydramnios and an adverse perinatal outcome would likely come in this group.Conclusions The antenatal hemodynamic indices of fetal UA and MCA can predict fetal conditions in oligohydramnios group and will offer a better evaluation of perinatal prognosis in comparison with only simple hemodynamics.
