INTRAARTERIAL DOPPLER FLOW MEASUREMENTS DURING RENAL-ARTERY ENDOVASCULAR STENT DEPLOYMENT - ABOLITION OF RESTING IMPEDANCE TO BLOOD-FLOW

This communication details the first reported case of renal artery int raarterial pulse wave Doppler obtained prior to, and following primary stenting of a renal artery stenosis. Doppler wave forms were recorded proximal, within, and distal to the lesion and reported with the angi ographic and hemodynamic results. The changes in average and maximal p eak velocities following stent deployment continued the abolition of t he resting transstenotic gradient and renal artery stenosis. Intraarte rial pulsed wave Doppler complements angiography and translesional gra dient measurements as a physiological marker of a successful procedure .
