Research progresses of hemodynamics in aortic isthmus of fetuses during the second and third trimester / 中国医学影像技术

ABSTRACT

The aortic isthmus (AOI) connects the blood circulation of fetal supraphrenic and subphrenic organs,reflecting fetal blood distribution directly and quickly.The waveform of AOI can demonstrate the fetal blood supply,the presence of intrauterine hypoxia and so on.Measurement of fetal AOI Doppler spectrum and related hemodynamic parameters may provide reliable indicators for early detection and positive intervention in fetal growth retardation,which is of great significance for increasing the detection rate of FGR and reducing the incidence and mortality of perinatal period.The research progresses of hemodynamics in AOI of fetuses during the second and third trimester were reviewed in this article.
