Frequently Asked Questions about CCSVI and MS What are the results of the liberation treatment so far?
Dr. Zamboni’s study treated 65 MS subjects with different types of MS (35 RRMS, 20 SPMS, 10 PPMS). There was no control group and all patients knew they had the procedure performed (“unblinded”). The doctor assessing them was also aware of the treatment (“unblinded”). 47% had re-stenosis of the vein that was dilated. While this was an important “pilot” study, Dr. Zamboni believes this requires further testing to validate his findings. Since then, several patients have paid for treatment outside of research studies. There is no careful or systematic follow-up of these patients to know how many benefit, how they benefit, what predicts who will benefit and how sustainable the benefit is.
