Utility of Renal Artery Duplex Ultrasound for Screening and Diagnosis of Coarctation of the Aorta in Adults

Abstract

Renal artery duplex ultrasound has been very successful in assessing renovascular hypertension. When renal artery velocities are within normal limits, but the Doppler spectral waveform is of small amplitude with a prolonged systolic rise, a more proximal arterial stenosis is suspected. We describe 2 cases of coarctation of the aorta in adults that were diagnosed with the assistance of aortic and renal artery duplex ultrasound.
