Value of Doppler Sonography for Predicting Clinical Outcome After Renal Artery Revascularization in Atherosclerotic Renal Artery Stenosis

An elevated RI should not exclude patients from a revascularization procedure because, although renal RI does correlate with blood pressure response to revascularization, it is not a useful parameter in predicting renal function outcome. Acceleration has no prognostic value.
