Abstract.
Objectives. To determine changes in the fetus cerebral blood flow in fetal hypoxia compared to the physiological course of pregnancy. The study was based on the hypothesis that hypoxia leads to significant disorders of cerebral circulation, which can be detected by Doppler.
Material and methods. The study included 126 pregnant women who underwent fetal ultrasound examination to detect fetal hypoxia, and they were divided into the main group with hypoxia and the control group without it.
Results. The study revealed that in the fetuses of the main group during the periods of 32-34 and 37-40 weeks of pregnancy, a statistically significant decrease in the resistance index in the cerebral arteries was detected, which indicates compensatory processes in a hypoxic situation.
Conclusions. The study confirmed that fetal hypoxia entails changes in the fetal cerebral blood flow, which is consistent with the results of other studies. A decrease in the cerebral resistance index (RI) in the anterior and middle cerebral arteries can be considered as an early marker of hypoxia, which allows timely diagnosing and correcting pathological conditions.
Keywords: fetal hypoxia, cerebral blood flow, dopplerometry, resistance index, cerebral hemodynamics, perinatal outcomes, ultrasound examination, pregnancy.
