I call my procedure a "successful failure", in that it did find an area of stenosis, but was unable to treat it.

As is usual for my atypical self, the problem they found is fairly unusual. Rather than my stenosis being caused by a collapse of the vein walls, or by a malfunctioning valve or anomalous membrane inside the vein, as is the case with the vast majority of people, it was found that the blockage of my right internal jugular vein is caused by a muscle bundle pinching it from outside the vein.

Therefore, when ballooning was attempted, it had no effect, and I've been told that if a stent was put in it would fracture within three years because of the pressure that would be put on it by the muscle. It looks like my only course of action may be to have traditional surgery to excise the muscle from my neck, but images of my venogram were looked at by Dr. Zamboni himself, and his impression was that the disruption in blood flow caused by the muscle bundle was not significant enough to warrant such major surgery.

Easy for him to say, he's not the one watching himself getting paralyzed.

I'll probably undergo another venogram early next year because my IR had trouble accessing and imaging my azygos vein the first time around. Since then, much has been learned. As I said in my previous post, the techniques and methodology being used during the procedure are being refined by the day, thus the recommendation that waiting a little while would be in most patients' best interest.
