The increase in diameter and flow in a fistula is not related to the increase of pressure in the vein. It is related mainly to the flow.
When we perform a vein graft in arterial surgery, for example in a femoro-popliteal location, there is no increase in the diameter but only an increase in the thickness of the vein wall..
The drawing gives the answer: the lenght of the anastomosis is far too long!
