My IR gave several very well thought out reasons for not implanting a stent. First, and most importantly, the location of my stenosis was in a very tight spot: not much space between the skull and the skin. He also mentioned that stents are capable of between 40,000 and 50,000 flex's before they might break into pieces, and that area involves a lot of motion. Lastly, if the stent had to be removed, it might involve surgery. Now that the exact location of my stenosis has been determined, if the veins relapse he will know right where to go.
