There is an interesting controversy raging in the Multiple Sclerosis (MS) world that reflects many of the issues we discuss at science-based medicine. Dr. Paolo Zamboni, and Italian vascular surgeon, has now published a series of studies claiming that patients with clinically defined MS have various patterns of chronic cerebrospinal venous insufficiency (CCSVI). Further Dr. Zamboni believes CCSVI is a major cause of MS, not just a clinical side-consequence, and is exploring treatment with venous angioplasty or stenting.
The claims have captured the attention of MS patients, many of whom have a progressive course that is only partially treated by currently available medications. There are centers popping up, many abroad (such as India), providing the “liberation procedure” and anecdotes of miraculous cures and spreading over the internet. There is even a Facebook page dedicated to CCSVI, and you can read the anecdotes for yourself. Many profess dramatic improvement immediately following the procedure, which seems unlikely even if Zamboni’s hypothesis is correct.
Zamboni is also getting attention from neurologists and MS specialists, who remain skeptical because Zamboni’s claims run contrary to years of research and thousands of studies pointing to the current model of MS as an autoimmune disease.
