Will stenosis always show high recirculation on transonic? We have a patient who at times would have prolonged bleeding. I believe it’s just because they’re putting the needle on the scar tissue. On times that it’s on new site we only have to wait 10 mins for bleeding to stop. His transonic does not show recirculation and no high pitch sound on auscultation.

A It depends upon the placement of the needles.If too close it should register as recirculation. But if it's true stenosis it should show an increase ABF over time.
B.EXPLAIN scar tissue. f you are cannulating the access through a keloid scar it will not notice a change.
