Dr. Benjamin is our renovascular surgeon, he just finished his
fellowship at Bowman gray - the mecca for renal reconstruction. He
says that the kidney never really dies with a renal artery occlusion
because of collateral flow. We almost always detect flow from
kidneys that have occluded renal arteries, which makes the study a
challenge - the old is it occluded or is it me question. Flow is
usually below 10cm/sec with a monophasic waveform. This is where
kidney size and renal function come into play.
