Her situation was different, it was one procedure initially and then three to correct the complications of each procedure. Then a final one, voluntary, to regain lost improvements if possible.
Dr. Sclafani's methods are not as aggresive as they were a month ago from what he has said in his thread lately. He too measures the vein using IVUS and uses that to guide how large he dilates, just as was mentioned above about a conservative doctor.
I look forward to when it's all figured it out. I dont think there is an answer to the OP 's question. For hyperplastic veins a succession of procedures a few weeks apart may be part of the protocol some day, as it is for AV fistula maturation, as drsclafni has talked about. That succession of procedures is a large number in a short time. Donnchadh's were many months apart, that may give the veins more time to recover than if it's closer. Each prcedure would do intimal injury so risk of hyperplasia might increase.
We hear of people who have improvements after the first procedure who lose them and then do not get them back, even when to all appearances the veins are flowing. It's kinda a mystery. I think it's more common to improve with each procedure but unknown.
javabean, let us know what the IR who s looking at your scans, if he thinks there is still stenosis, if his advice is to go for a third? I think it is an important question, now that people are getting into multiple venoplasties. CCSVI keeps changing! It is fascinating.
