Abstract:
Objective: To evaluate the clinical value of aortic isthmus pulsatility index (AoI-PI) on intrauterine hemodynamic changes in fetus of preeclampsia patients. Methods: Totally 261 pregnant women who underwent prenatal ultrasound were selected, including 214 normal pregnant women (47 selected as control group) and 47 preeclampsia patients (case group). The changes of fetal AoI-PI with gestational age were observed in 214 normal pregnant women. Fetal AoI-PI and cerebroplacental ratio (CPR) were compared between 2 groups. Results: Fetal AoI-PI in normal pregnant women slightly increased with gestational age. Fetal AoI-PI in case group was higher than in control group (P<0.001), while CPR was lower than that in control group (P<0.001). The abnormal changes of AoI-PI were earlier than those of CPR in case group. Conclusion: Fetal AoI-PI can indicate hemodynamic changes in fetus of preeclampsia patients.
