LYON, FRANCE—Chronic cerebrospinal venous insufficiency (CCSVI) appears to occur at a similarly low rate among patients with multiple sclerosis (MS), patients with other neurologic disorders, and healthy controls, researchers reported at the 28th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS). CCSVI also appears to occur at similar rates among patients with various types of MS.
The study results cast doubt on the hypothesis, first proposed by Paolo Zamboni, MD, Associate Professor of Morphology, Surgery, and Experimental Medicine at the University of Ferrara, Italy, that CCSVI is an important factor in MS. The findings also call into question Dr. Zamboni’s proposal that a type of angioplasty known as “liberation therapy” could be an effective treatment for patients with CCSVI and MS.
