Is it simple restenosis or is it an occlusion? I too would seek a second opinion. My left jugular partially restenosed but my right jugular stayed open. My best results came after the second procedure.
There has been talk about the possibility of diminishing returns with multiple procedures, but there is no obvious explanation for such a phenomenon.
There is also the possibility of stenosis that has been missed. Based on the abstracts we've seen, approximately 10% of patients might have a stenosis that is missed if IVUS is not part of their treatment protocol. (The math is a guesstimate, which drives me crazy, but by my own estimation, based on only two abstracts, it's about 25% of patients with azygous disease, which is about 40% of all CCSVI patients.)
Did you have a loss of improvements? That would indicate restenosis as well.
