Okay. Very, very quickly, I want to underline that the gold standard in medicine to detect a stenosis or a narrowing in a vessel is gold standard angiography. I formally invite members of the committee to visit us, and I will be pleased to show you, in the computer system of our university hospital, 130 consecutive cases of this narrowing.
So this proof is completely undebatable, and probably if you follow other paths to demonstrate that this does not exist, it will certainly be the wrong way of confronting the problem, because the consensus conference on venous malformations inserted CCSVI in the official guidelines of the medical vascular society.
