My left jugular during procedure #1 in February:
The first image is before the ballooning. You can see the very tight, near total 99% stenosis.
The second image is the ballooning. Notice the waist on the balloon.
The third image is a subsequent ballooning. Notice that the waist is gone.
The fourth image is the flow at the end of the procedure. Compared to the first, it looks much healthier.
My left jugular during procedure #2 in July:
The first image is the jugular before the treatment. It is not as bad as it was initially back in February nor as good as it was post-treatment in February. It is wide in the midregion of the jugular and narrow at the top and bottom. The narrowing at the top is physiological and does not need to be treated.
The second image is the first ballooning. Notice the waist. Also notice that it's a pretty short balloon.
The third image is a subsequent ballooning. It still shows a waist. The balloon looks much longer. It does not appear that the waist resolved.
The fourth image shows the flow after the procedure. It is improved from the first. But I do not know how durable this will be.
Any IRs present are more than welcome to comment. Would you have treated this stenosis (in the second group of images)? Would you have stopped after the ballooning shown in the second image, which was done with a 10 mm balloon, or the third image, which was done with a 12 mm balloon, or would you have continued on? Is the final result in your experience likely to be durable?
