Significance of Inferior Vena Cava Variability and Uterine Artery Blood Flow Measured by Ultrasound in Evaluating Right Ventricular Function of Patients with Gestational Hypertension
Objective To explore significance of inferior vena cava variability and uterine artery blood flow measureed ultrasound in evaluating right ventricular function of patients with gestational hypertension.Methods The paper chose 80 pregnant women with late pregnancy induced hypertension in Dongfeng People's Hospital from March 2021 to November 2022 as observation subjects in observation group,and 80 healthy pregnant women in late pregnancy with prenatal examinations at the same time in control group.Variation of inferior vena cava diameter and uterine artery blood flow spectrum was measured by Doppler ultrasound,including pulsatile index(PI),resistance index(RI)and systolic peak flow velocity/end diastolic flow velocity ratio(S/D).Difference in above indicators was was compared and analyzed between two groups.Results RSBI index of observation group was higher than control group,while dIVC index was lower than control group.Difference in two indicators between two groups was statistically significant,(P＜0.05).The PI,RI,and S/D indicators of observation group were higher than control group,and difference was statistically significant(P＜0.05).Conclusion Ultrasound measurement can evaluate degree of inferior vena cava variability and uterine artery hemodynamic parameters of pregnant women objectively and quantitatively.Difference in inferior vena cava variability and uterine artery hemodynamic indicators between pregnant women with gestational hypertension in late pregnancy and healthy pregnant women in late pregnancy can provide diagnostic basis for clinical practice,help clinicians pay more attention to right ventricular function of patients with gestational hypertension,and achieve goal of improving maternal and infant health.
