I'm sorry you need another go 'round.
Jeff's a high upper, like you. He had serious dural sinus stenosis, too. His right side stent has remained open and flowing at 100%, but his left has been problematic, at one point, deferring to collaterals again. He's needed two repeat angios to reopen the area, and it has been reopened each time. The time between angios has increased. He will be on plavix for life.
The problem is that the area needs good flow and shear stress to endothelialize correctly, and if the flow is sluggish or weak, intimal hyperplasia can form.
Jeff's hydrating, doing cardiovascular exercise 5 times a week, and eating a heart healthy, low calorie diet, including proteolytic enzymes and other supplements in the Endothelial Health program. We hope that the left side will endothelialize as well as the right has. So far, so good for this round. This is a lifetime commitment, just as if you were a heart patient working with a cardiologist...I know, that's hard to hear, but for Jeff--he feels so much better, it's been worth it. I hope it will be for you, too--
