The advent of sonography has changed the practice of obstetrics by providing a window to the womb through which the anatomic structure of the fetus can be evaluated. The addition of Doppler flow studies of maternal and fetal vessels has provided a tool where the physiology of the maternal-fetal unit can be assessed. This information can provide the physician and the patient with vital information for a subsequent approach to the pregnancy. The use of fetal Doppler blood flow studies has become common in the evaluation and management of pregnancies complicated by conditions such as suspected fetal growth restriction and red blood cell isoimmunization to guide intrauterine therapy and delivery. The most commonly assessed Doppler flow studies of the fetus are the umbilical artery and middle cerebral artery (MCA). Doppler flow studies of the MCA are used in the assessment of the fetus at risk for anemia and growth-restricted fetus. Doppler flow studies of the umbilical artery can reflect abnormalities in "down-stream" or the fetal side of placental resistance, and the assessment of the maternal vasculature evaluates "up-stream" blood flow or the maternal side of placental resistance. The purpose of this review is to describe the clinical utility of uterine artery Doppler flow studies in the prediction of adverse pregnancy outcomes in low and high risk populations.
超声检查的出现改变了产科的实践，它为子宫提供了一个窗口，通过这个窗口可以评估胎儿的解剖结构。对母体和胎儿血管进行多普勒血流研究，提供了一种评估母胎单元生理状况的工具。这些信息可以为医生和患者提供有关后续妊娠处理的重要信息。胎儿多普勒血流研究在评估和管理合并诸如疑似胎儿生长受限和红细胞同种免疫等情况的妊娠中已变得很常见，以指导宫内治疗和分娩。最常评估的胎儿多普勒血流研究是脐动脉和大脑中动脉（MCA）。大脑中动脉的多普勒血流研究用于评估有贫血风险的胎儿和生长受限胎儿。脐动脉的多普勒血流研究可以反映胎盘阻力“下游”或胎儿侧的异常情况，而对母体血管系统的评估则是评估“上游”血流或胎盘阻力的母体侧。本综述的目的是描述子宫动脉多普勒血流研究在预测低风险和高风险人群不良妊娠结局中的临床应用。
