Hi Kim,

I use the criteria from this article by Cossman, et al.  It is old but the criteria works well.  Many labs I know use this criteria.  It has both ratios and PSV values.  The PSV criteria would be help in the situations you mention.

Hello!

What arterial duplex criteria are you guys using? The one I'm using now utilizes velocity ratios, but I have found this difficult to use for EIA and proximal SFA/Profunda strictures. 

Thank you in advance!! 🙂
