Had an interesting case this week:
43 year old for CABG needs radial harvesting.
Arteries look normal. Allen's test is where things get confusing for us:
right #1: flatline with radial compression. Decrease in pulsatility with ulnar compression
right #2-5: flatline with radial compression. Flatline with ulnar compression.
left digits: all flatline with radial compression. 2 and 3 show decrease in pulsatility with ulnar compression and 1,4,5 are normal with ulnar compression.
Can anyone explain the results of the right hand allen's test?
Thank you in advance,
