I am due to have an MRV next week, looking at the above images is there any area on the left illiac vein i can tell the IR to look and possibly balloon/stent ?
having mid azygous stenosis is highly suspect in my opinion. Often it looks stenotic but it is a phasic narorowing. Ask if there was any waist on the balloon.
nonetheless, if it was ballooned and the vein is nicely opoen now, that is great.
all the more reason to clarify whether this is may thurner or not.
but why are your two images so grossly different?
I think it is in the technique of performance of the iliac veinography. The first time, catheteriation was from the right and the cathter was advanced from right to left. the tip of the catheter is facing toward the feet and it likely has its tip in the internal iliac vein, leading to the visualization of the pelvic veins. .. in the second one, the catheter is facing toward the head. and positioned in the external iliac vein. thus the branches of the internal iliac vein are not opacified.
I now question the diagnosis of MTS
but you got to check it out, perhaps the MRV can be done prone.
