Another small negative CCSVI study

Epub ahead of print: Auriel et al. Extra-cranial venous flow in patients with multiple sclerosis. J Neurol Sci. 2011 Aug 3.

27 MS'ers were compared to healthy control subjects.

Results: Except for one MS'er, blood flow direction in the internal jugular veins was normal in all subjects. 

No significant difference was found between subjects and controls.

Conclusion:  The investigators found no evidence to suggest that MS'ers have an excess of CCSVI. In addition they failed to observe a typical venous flow pattern in MS'ers. Until carefully designed controlled studies to investigate CCVSI have been completed, invasive and potentially dangerous endovascular procedures as therapy for MS should be discouraged.
