彩色多普勒超声检测子宫动脉及脐动脉在晚发型宫内生长受限中的价值

目的：彩色多普勒超声检测母体子宫动脉和胎儿脐动脉在晚发型宫内生长受限的血流动力学价值及预测不良围产儿结局。 方法：分析晚发型宫内生长受限的孕妇169例和58例同期分娩正常孕妇,于妊娠期产前超声多普勒分别检测子宫动脉和脐动脉的搏动指数(PI),比较各组动脉血流异常及妊娠结局不良发生率。 结果：晚发型FGR孕妇中胎儿宫内窘迫所致急诊剖宫产、早产、新生儿1min Apgar评分评分、转入NICU、子宫动脉血流异常及脐动脉血流异常例数发生率分别为48.5%、39.6%、31.4%、35.5%、31.4%和21.9%,均高于对照组(P <0.05)；在晚发型宫内生长受限孕妇中妊娠结局不良发生率,D组(子宫动脉和脐动脉血流均异常)明显高于A组(子宫动脉和脐动脉血流均正常),而除了胎儿宫内窘迫所致急诊剖宫产外,B组(子宫动脉异常,脐动脉正常)妊娠结局不良发生率高于C组(子宫动脉正常,脐动脉异常)。 结论：超声多普勒检测检测晚发型胎儿生长受限孕妇的子宫动脉和脐动脉的血流动力学,是了解围产儿预后的有效监护手段,在晚发型胎儿生长受限孕妇中,子宫动脉和脐动脉均异常,提示妊娠合并症增加和围产儿结局不良。

Uterine and umbilical artery Doppler predict the outcome of Late Onset Fetal Growth Restriction

Objective To assess the value of Hemodynamics of uterine artery (UtA) and umbilical artery(UmA) in monitoring Late Onset fetal growth restriction (FGR) is related to adverse pregnancy outcome. Methods 169 pregnant women with Late Onset FGR and 58 normal pregnant women were included in the study. The pulsatility index (PI) in both UtA and UmA were assessed by color Doppler ultrasonography, The hemodynamics changes UtA and UmA were compared with the perinatal outcomes. Results caesarean delivery , premature delivery, neonatal asphyxia, admission to NICU,abnormal uterine artery and umbilical artery Doppler incidenceSrate in the Late Onset FGR group were higher than those in control group (P <0.05),
