胎儿动脉MCA、MCA与UA的阻力指标在高血压产妇母婴结局预测价值
Journal of Inner Mongolia Medical University(2019)
Abstract
目的:探讨胎儿大脑中动脉(middle cerebral artery,MCA)与脐动脉(umbilical artery,UA)的阻力指标在高血压产妇母婴结局的预测价值.方法:选取我院妇产科147例妊娠期高血压产妇,按疾病轻重分为轻度组78例,重度组69例,选择正常孕妇172例作为对照组.采取彩色多普勒超声检测胎儿MCA与UA阻力指标并计算其S/D、PI及RI比值,用各阻力指标及比值与妊娠结局作ROC曲线.结果:对照组与重度组UA、MCA阻力指标及比值组间差异显著(P<0.05),轻度组与重度组UA、MCA阻力指标及比值组间差异显著(P<0.05).三组妊娠结局比较有显著差异(P<0.05).经ROC分析妊娠结局,MCA与UA阻力指标优于单一应用MCA或UA.结论:疾病恶化后胎儿UA阻力指标上升,MCA及MCA与UA阻力指标下降,RIMCA/UA对妊娠期高血压疾病预测价值佳.
