Carrie,
In answer to your questions, yes the adrenal's will supply the distal
renal arteries when the main renal artery is occluded.  You may also find
collateral vessels from the spleen as well as from the liver. Since there
are several capsular vessels present the kidney may actually have
perfusion but the distal renal artery may not have any flow present as
well.
The waveforms will still be low resistant but may not have as high
diastolic flow present and the systolic upstroke may also be dampened.  I
have seen velocities that ranged from 130 cm/s to 30 cm/s in collateral
vessels to the kidneys so there is no magic number as to what you will see
in velocities.  I hope this helps and good luck!
