Perhaps you might share the titles of some of those papers.
You give ONE paper on ONE healthy patient followed for only 4 years, patientx....that's not exactly conclusive evidence.
In the present study, we demonstrated that the healthy brain can tolerate bilateral jugular vein ligation during radical neck dissection by opening invisible channels.
My husband's brain was anything but healthy when he was treated for severe bilateral jugular stenosis. And he had it for over 30 years, since he lost his peripheral eyesight at age 10. Pseudotumor cerebri (what he had) is linked to jugular vein ligation or blockage.
here you go:
Titles and authors of 14 papers showing a variety of effects of jugular ligation on the brain on numerous patients- including change in evoked potentials, interference with reabsorption of CSF, ischemia, blindness, optic neuropathy and edema and 8 deaths. Not exactly benign.

CCSVI is most-likely a chronic, lifelong accumulation of injury to the brain, spine, and optic nerve. That's why Dr. Zamboni followed those kids in Sardinia and found that 90% had MS 20 years later.
Dr. Zamboni’s personal journey leading to the rediscovery of the vascular link to MS, and his subsequent elaboration of this connection, began more than twenty years ago, when he was a vascular surgeon in Sardinia, Italy. Sardinia is geographically isolated and, for reasons largely unknown, contains very high rates of MS. Studying children in Sardinia, Dr. Zamboni discovered that a great number of them had malformations in their jugular veins. This work lead to one of his earliest professional publications, “The so-called primary venous aneurysms,” published in Phlebology, in 1990.
