WebThe normal ratio of renal artery PSV to aortic PSV is less than 3.5 (, 18,, 30). What is normal blood velocity? Normal human peak systolic blood flow velocities vary with age, cardiac output, and anatomic site. At the aortic valve, peak velocities of up to 500 cm/sec may be possible. … Venous velocities are generally less than 20 cm/sec. Web1 de dez. de 1993 · Doppler parameters measured in the distal renal artery included systolic acceleration, acceleration time, peak systolic velocity, deceleration in late systole, pulsatility and resistivity indexes, and waveform features in early systole. RESULTS: Angiograms demonstrated 28 stenotic renal arteries. WebOf the multiple renal Doppler indices recorded, the peak systolic velocity in the transplant artery was the best discriminating measurement for the detection of renal artery stenosis.
