This website is about the hypothesis of the association of "Chronic cerebrospinal venous insufficiency" (CCSVI) and multiple sclerosis (MS). The pattern of CCSVI was described by Prof. Zamboni. We list research such as scientific publications or conference presentations and media coverage.

First Blinded Study of Venous Insufficiency Prevalence in MS Shows Promising Results

Press release February 9, 2010, University at Buffalo

BUFFALO, N.Y. – More than 55 percent of multiple sclerosis patients entered in the initial phase of the first randomized clinical study to determine if persons with MS exhibit narrowing of the extracranial veins causing restriction of normal outflow of blood from the brain were found to have the abnormality, neurology researchers at the University at Buffalo have found.

When the 10.2 percent of subjects in which results were border line were excluded, the percentage of affected MS patients rose to 62.5 percent, preliminary results show, compared to 25.9 percent of healthy controls.

These preliminary results are based on the first 500 participants in the Combined Transcranial and Extracranial Venous Doppler Evaluation (CTEVD) study, which began at UB in April 2009. Investigators are planning to examine 500 additional subjects, who will be assessed in the second phase of the study with more advanced diagnostic tools. Complete data on the first 500 will be presented at the American Academy of Neurology meeting in April.

Consensus Document of the International Union of Phlebology (IUP) – 2009

A consensus conference on venous malformations[uip09] – headed by Prof. Byung B Lee from Georgetown – and experts from 47 countries – studied the evidence and unanimously voted in favour of officially including the stenosing lesions found in CCSVI in the new Consensus document and Guidelines.

This paper can be brought to interventional radiologists and vascular surgeons. CCSVI lesions are classified as a truncular venous malformations - which means that vascular doctors have now classified this disease, CCSVI, as congenital- and preceding MS lesions.
