I do hope those in close contact with our CCSVI experts can obtain their
opinion on this procedure and the Texas doctors involved.

This is very important. How ... and did they measure bloodflow before and after...

I do hope Dr.Zamboni weighs in on this ........

Did I just miss it .....or were there no reported results and conclusions in the outcome of this patient ?

Seems sort of like a case of chronic cerebral spinal venous insufficiency treated by a saphenous vein bypass in 1998. They might not have looked for peri-ventricular, peri-venular lesions. They were busy. Was it my imagination or did they say it treated both the myelopathy and the hydrocephalus, and did I read right, that there was venous hypertension and *reflux*? Didn't they say if the venous pressure wasn't there, the graft would not have held up as well? Sounds like there is a delicate balance between pressure that holds up the bypass and makes it patent, and pressure that causes reflux and epidural veins that press too hard or get too big. The whole thing sounds very ad-lib compared to rigorous double-blind sham controlled randomized trials. My brother got his hydrocephalus treated by such a ground-breaking operation when he was a newborn. He would have died, and it hadn't been done much, if at all. Here, ultrasound and venography were essential, or they might not even have had a diagnosis.

In the article it mentions drilling into the skull to attach the new jugular vein to the venous sinus. That is a more complicated procedure than if there is healthy jugular vein on either side of the occlusion. Then just the occlusion can be swapped out and the graft attached to healthy vein. None of the jugular vein grafts or patches have involved skull drilling so far!

Dania did the by-pass tie into the jugular vein above or below the valve?

No valve now. Plus the brilliant Dr Hernandez, when he put in the piece of the saphoneous vein inverted it, so the valves are pointing downwards.
