Ultrasonics is very important for the control of risk pregnancies. Routinely, Doppler-ratios are used to assess fetal danger. The aim of the presented study was to clarify whether measurement of absolute blood flow velocity is useful for the assessment of fetal development as well. For this purpose we examined the fetal aorta in 149 patients: 90 patients with fetal growth retarded fetuses and 59 patients with normally developed fetuses. Systolic and diastolic peak velocities and the resistance index (RI) were measured. The absolute velocities did not show any correlation to the fetal growth. Moreover, there was no correlation between systolic peak velocity and resistance index, independent of degree of pathology. The diastolic peak velocity however correlated with high significance to the RI thus being directly dependent.
超声检查对于高危妊娠的监测非常重要。通常，多普勒比值用于评估胎儿危险程度。本研究的目的是阐明绝对血流速度的测量对于评估胎儿发育是否也有用。为此，我们对149例患者的胎儿主动脉进行了检查：90例胎儿生长受限的患者和59例胎儿发育正常的患者。测量了收缩期和舒张期峰值速度以及阻力指数（RI）。绝对速度与胎儿生长无任何相关性。此外，收缩期峰值速度与阻力指数之间也无相关性，与病理程度无关。然而，舒张期峰值速度与阻力指数高度相关，因此直接相关。
