In the process of reaccrediting and ICAVL is requesting reference criteria. We do not grade these stenosis, just simply state increased velocities noted in eca which is suggestive of stenosis. I still need published criteria. I found an article by Michael Jaff for CCAstenosis, and I think the new book by Strandness may have ECA criteria. Could use any help you have.
