Could you explain R versus L entry for CCSVI treatment? I understand L is preferred for catching MT Syndrome but are there other reasons and is it more dangerous than going in through the R side?
thank you in advance!

drsclafani wrote:mshusband wrote:Dr. Sclafani ... what role do you suspect the inferior vena cava could play in issues in the legs?
i do not think that the inferior vena cava plays a role in ccsvi unless the usualy suspected veins are involved. Then alterations of flow within other structures can make it worse.

I have recently watched a very good forum by Dr. George Jelinek the writer of several books on MS and a research publisher from Australia, he also has MS.
See the talk at http://www.msakl.org.nz/.
"Professor Jelinek was invited to present the Keynote Address to the Focus on MS Conference run by the MS Society of New Zealand on Saturday 18th September 2010. He chose to discuss the value of medical evidence, what weight researchers put on various trials, and how bias and conflict of interest can influence the results of these studies. The talk particularly focuses on drug-company sponsored research, and the often hidden or unreported flaws in clinical trials that raise questions about the real efficacy of some of the currently used disease-modifying medications. This is an important talk for those of us wishing to get a really balanced perspective on the treatment options for MS, rather than blindly following a drug-only approach."
The whole video is worth looking at, it is 1.5 hour long. I think it is valuable information if you are to design studies for CCSVI treatments.
Most of the video is about the flaws and biases in RCT research, mostly by Pharmaceutic Industry to sell there products. Very, very good content.
The very end has a comment he made about CCSVI angio problems from stretching veins that in his words has been known about for some time as a problem in angio treatments having restenosis.
Can you comment on the 'known' complication of restenosis after angio that he speaks briefly about please.
Dr. Rubin said ...Last week, he treated a woman who had the vein procedure in Mexico.
"We found extensive clotting in the left arm reaching into the chest veins, and some of the clots had broken off and travelled to her lungs, which is called a pulmonary embolus, which is life threatening, potentially life-threatening complication."
Johnson wrote:Dear Doctor,
I am wondering, but have been reticent to ask - lest I have missed a previous Q & A - what is an "incompetent valve"? Is it a generic term that would cover inverted valves, fused leaflets, etc., or is it a more specific pathology?
In my second round, a Doppler US revealed "incompetent valves" and the venogram suggested stent (declined), then a cutting balloon, but cutting balloons apparently don't come as large as the 18 mm required for my LIJV. What, if anything, might I infer from this limited information? Would an incompetent valve fall into congenital malformation, or could there be another antagonist?
Thank you, sir.
My question results from that (and, again, I'm sure it's one that has been asked and answered several times).
What constitutes a clinical narrowing? (maybe those are the wrong words) ... but if a vein is narrowed 20% ... would you balloon it if there was potential reversed flow?
Are valves the main issue? - and if so, does running a guide wire through the veins pose any issues with moving them and not being able to see accurately what is happening then?
Do you think there could be potentially any IVC issues, or have you seen any, related to CCSVI? (I know that's not part of the theory, but has anyone looked?) I have no reason to suggest there may be ... I just wonder.

Its not an easy place to be... but it will get better.
My question concerns Endothelin 1. I am an RN ( x 38 years) with a good handle on anatomy and physiology. My interest is in the function of Endothelin 1.
It is my undertsnading that Endothelin 1 is made by all people to maintain the health of the lining of our vessels. It is also my understading that increased shear stress and hypoxia are triggers that increase production of Endothelin 1- I am guessing its the bodies way to reinforce the vessel intergrity.
I have learned that Endothelin 1 in high levels can increase fibrosis( fibrotic changes) and hypertrophy (thickening) of the vessels/valves. So IF the person is born with this congenital condition , say at a minor blockage in early life and then over time, with shear stress and hypoxia as triggers the Endothelin levels soar and the CCSVI lesions/vessel get worse.......then the shear stress and hypoxia get worse etc etc
Its sort of a cycle....over many years the vessels would be stiffer, stenosis could be worsening and valves could be thickened and more of a blockage. Of course all of this would cause more iron to be laid down in the parenchyma too doing its own bit to contribute to damage. The iron and hypoxemia and hypogylcemia in the brain leading to axonal and oligodendrocyte damage and maybe even cell death. Could the extremely high Endothelin levels cause the venocentric MS lesion formation ( sort of like sandbagging the walls?) And the WBCs be chrochically activated as the "clean up crew"?
Its my undertsnading that pwMS have a much higher ( hundred times higher)than normal Endothelin 1 level. After successful PTA would the Endothelin level 1 drop because their triggers are gone?? How long does that take? Would the fibrotic and hypertrophic changes decrease? Are there people studying this?
Sorry to blast you with so many questions but I don't know who to ask these questions of.
Thanks in advance and I will totally understand if the answer is "we don't know yet"

Does it have to be done on a flat table? Is there any way to use something like an angled bed or even something like a procedure "chair" that could accommodate a person who had trouble being flat? Thinking creatively here. I guess that wouldn't work with the specialized equipment?

Dr. Sclafani: One of the most simple rules of chemistry is that heat speeds up reactions. A cold dead body will tell you that heat liquifies blood. I have had the liberation procedure and feel much better.
But heat continues to be my enemy. The solution, I know, is to get up off my kiester and get some exercise,
but the problem is, I spend a lot of time with my computer on my lap *heating* it up. My legs will twitch and complain if I do not have an insulating device between it and them.
They also complain when I am in bed. I believe (possibly wrongly) that reflux is happening when I am lying down. I can get my legs tolerable if I put them out from under the covers. I think maybe being under covers and retaining heat makes my blood thinner, and reflux happens more easily with the jugulars wide open and the blood moving well. The reference at http://www.thisisms.com/ftopict-14541.html says arm position seems to make a difference (but does not say what position). I guess all of this may resolve when I am off Plavix, but is this hyperactive imagining, or ongoing brain damage (or both )? Do you think that having so much heat on my legs when sitting can thin my blood and allow reflux, which then makes my legs twitch? Can you comment at all?

It's been eight months now! It may be the usual thanks but it is an unusual commitment, well worth acknowledging as often as we do.
