| 中文摘要: |
| 胎儿主动脉峡（AOI）连接膈上与膈下血液循环，可直接、快速反映胎儿血流分布，其波形可反映胎儿血液供应及是否存在宫内缺氧等情况。测量胎儿AOI频谱多普勒及相关血流动力学参数，可为临床早期发现并积极干预胎儿生长迟缓（FGR）提供较为可靠的指标，对于提高FGR检出率及降低围生期发病率与死亡率具有重要意义。本文对胎儿中晚孕期AOI血流动力学变化规律的研究进展进行综述。 |
| 英文摘要: |
| 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. |
