WebA, Oblique sonogram of renal transplant shows significantly elevated peak systolic velocity (PSV) at origin of main renal artery (peak systole 426 cm/s and diastole 191 cm/s) with surrounding color Doppler bruit. Color parenchymal flow is significantly decreased. View larger version (107K) Webdiagnosed by no flow in the renal artery. We have included two analyses. Our main analysis includes occlusion in the “greater than” groups so that it is those that have no flow or a PSV equal to or greater than a specific velocity (eg, no flow or a PSV 285 cm/s for 60% RAS).
