I currently like to use duplex to evaluate the palmar arch artery (and it is much less time consuming than digital tracings and I'm scanning the arm anyway for diameter measures). I place the probe on the palm of the hand along the pad of the thumb and find the distal radial artery/palmar arch. I use pulsed wave Doppler to sample that region and manually compress the radial artery. If the flow reverses, the palmar arch is intact. If flow is totally absent with radial compression, the palmar arch is likely non-intact.

Subject: Palmer Arch/Ulnar Patency for CABG
Ok...I need some input. My co-worker and I are not performing our evaluations
for Palmer Arch Evaluations and Allens Test the same. He is old school and I
graduated 3 years ago. My ratio for harvestable Radials was 58% for 2011
and theirs were 13% There is question on who is going the procedure
correctly and due to limited documention on this subject, I am unable to find
any good material to support the process.
Is there anyone out there who has anything or who is willing to share
documentation, or even email me how they do their Allens test and if they use
another method of testing the Palmer Arch, what it is and what they do. We
use our Parks machine to test the Arch again after the Allens test to see if we
get the same results.
Help please!!!! :)
I will share with you my process I do if you want and you can critique it....
