Dr. Cumming,
Does the "decision making" as an IR that you mentioned come from the IVUS or from experience or intelligence, or other factors, or a combo of these things?
As I mentioned in other posts, I don't want to end up getting 5 treatments over the next year, like others I have read about.
What is the best way to know that I am doing what I can to reduce the chance of restenosis and get the best treatment available--Is it the doctor I choose or the diet and exercise and lifestyle I do after the procedure--Or is it completly unpredictable and uncontrollable?
Thanks.
Its a combination and balance of all those things (plus a few others). There is no question about a learning curve for new operators.
The last year has seen several different approaches. The latest trend has been towards big balloons with the goal of "popping" the annulus. Some have claimed increased patency doing this (however, they do no follow up imaging so they do not know what is happening).
I have seen a few severe restenosis and occlusions post aggressive venoplasty.
IVUS has many benefits. It allows you to find stenosis not apparent on venography and to determine what is causing the stenosis (ie valve leaflets, annulus). And I think it allows better balloon selection. I think we can reduce restenosis by minimizing the trauma to the vein wall. No proof yet.
I have no concrete evidence if this approach is any better or not. Again, we must remember, that since there is still no conclusive evidence the procedure works, we want to make sure we minimize any downside of the procedure. In my experience, oversized balloons can actually make things worse.
