First results from an NMSS-supported study investigating CCSVI (chronic cerebrospinal venous insufficiency) using several different imaging techniques to examine blood outflow from the brain have been published.
Researchers at the University of Texas Health Science Center at Houston used Doppler ultrasound to investigate venous drainage in 276 people with and without MS. They found that there is much less prevalence than previously reported by other groups and no statistical difference between those with MS and those without MS.
The results are in agreement with a recently published observational study from Italy which studied 462 patients who had undergone endovascular treatment for CCSVI and found that there was no evidence of clinical benefit.
