This turned out to be a long post that doesn't necessarily answer your question with any clarity. Sorry, I was just thinking via keyboard.
Maybe it will lead to others chiming in with better answers though.
I would assume if you were involved in a strictly controlled trial of either CCSVI or Revimmune, neither would want results muddied by having you try both until follow-up is complete; which can be years, depending on trial terms.
Of course if treatment is provided on a compassionate basis, you may have more freedom.
I know Stanford is not running official trials yet, although I have to believe they will be at some point. It looks like JH is getting ready to recruit for Revimmune trials. Will they continue offering treatment on a compassionate basis while running trials? I don't know, but sometimes institutions are limited in what they can offer outside an official study.
Just a couple of thoughts:
The folks at JH use a Hickman line to administer meds and draw blood. It's a venous catheter that is inserted at your jugular vein. A possible problem with stents in your jugs? I don't know, but worth asking the question.
Of course they could always use a PICC instead of a Hickman, or you could put up with multiple needle sticks, if they were willing to go that route. I'm sure the convenience of a line is preferable though (for them and for you)
I know that keeping an eye on what is happening with your blood is critical after both CCSVI and Revimmune. Honestly I think many PCP's would be intimidated with the follow up care for either, let alone both.
I'm pretty sure Mel is a year+ out from Revimmune treatment. I would think there would be more risk if you were looking at trying both CCSVI and Revimmune closer together, but that's not medical knowledge talking, just gut feeling. But maybe that's not your intent anyway?
Good Luck with your decision!
