PY - 2017 T2 - Fleischer's Sonography in Obstetrics and Gynecology: Textbook and Teaching Cases, 8e AB - This chapter focuses on the Doppler interrogation of the fetal circulation. Other chapters in this book focus on Doppler velocimetry of the uterine arteries and fetal echocardiography. Randomized clinical trials have demonstrated that Doppler examination of the umbilical arteries can reduce perinatal mortality. Therefore, practitioners need to be familiar with the sampling, interpretation, and clinical significance of these vessels. Similarly, Doppler examination of the venous system (ductus venosus, inferior vena cava [IVC], and umbilical vein) are informative of cardiac function and identify a fetus at risk for impending in utero death. Finally, examination of the peak systolic velocity of the middle cerebral artery has become important in the assessment of fetal anemia. This chapter reviews the anatomy, physiology, Doppler waveform morphology, normal ranges, and interpretation of an abnormal waveform in clinical practice.
