彩色多普勒超声量化评估参数在肾动脉狭窄性高血压中的应用价值OA

Objective:To explore the application value of color Doppler ultrasound quantitative evaluation parameters in the diagnosis of renal artery stenosis induced hypertension.Methods:114 patients with renal artery stenosis induced hypertension were selected as the observation group,and 114 healthy individuals were selected as the control group.Color Doppler ultrasound was performed to measure and compare parameters such as peak systolic velocity(PSV)and end diastolic velocity(EDV)of the renal artery.Results:The PSV of the observation group was significantly higher than that of the control group,and the EDV was significantly lower than that of the control group(P<0.05).Drawing receiver operating characteristic(ROC)curves shows that each parameter has good diagnostic efficacy for renal artery stenosis,and combined detection is superior to a single parameter(P<0.05).As the degree of renal artery stenosis worsens,PSV,RAR,and AT gradually increase,while EDV gradually decreases(P<0.05).Pearson correlation analysis showed that PSV,RAR,AT were positively correlated with the degree of renal artery stenosis(r=0.818,0.819,0.716,P<0.05),while EDV was negatively correlated with the degree of renal artery stenosis(r=-0.865,P<0.05).Conclusion:Color Doppler ultrasound quantitative evaluation parameters have important application value in the diagnosis of renal artery stenosis induced hypertension.
