Doppler ultrasound in pregnancy – quality requirements of DEGUM and clinical application (part 2)

Abstract This second part on Doppler sonography in prenatal medicine and obstetrics reviews its clinical applications. While this has not become the initially anticipated screening tool, it is used for diagnosis surveillance of a variety fetal pathologies. For example, sonography-based determination uterine artery blood flow indices an important parameter first trimester multimodal preeclampsia risk assessment, increasing accuracy providing indication prophylactic treatment with aspirin. It also significant implications growth-restricted fetuses third trimesters through Doppler-sonographic analysis umbilical artery, middle cerebral ductus venosus. Here, especially hemodynamics venosus provides critical criterium birth management severe, early-onset FGR before 34 + 0 weeks gestation. Further, maximum velocity central anemia which been significantly improved by analysis. However, to note that mentioned improvements can only be achieved highest methodological quality. Importantly, all these analyses are applied twins higher order multiples. differential specific complications such as TTTS, TAPS TRAP, application indispensable. To conclude, successful requires both exact methodology precise pathophysiological interpretation data.
