Doppler ultrasound applications in normal and complicated pregnancies are presented in this article. Anatomy and pathophysiology of fetal placental blood flow are described. Potential pitfalls in the evaluation of fetal placental blood flow are explored. Doppler flow velocity waveform analysis combined with other clinical and physiologic information is valuable in monitoring of the high-risk pregnancy. Duplex technology may also be useful in the first trimester.
本文介绍了多普勒超声在正常妊娠和复杂妊娠中的应用。描述了胎儿胎盘血流的解剖学和病理生理学。探讨了评估胎儿胎盘血流时可能存在的陷阱。多普勒血流速度波形分析结合其他临床和生理信息，在高危妊娠监测中具有重要价值。双功超声技术在孕早期也可能有用。
