CCSVI means that the blodflow from the
brain is limited by defect veins with abnormalities.
In 2009 the Italian vascular surgeon
Zamboni diagnosed CCSVI with ultrasound technique and he also
reported about 65 RRMS patients who were operated on the condition
using angioplasty to improve the blood flow. The
patients seemed to feel better after the procedure
The theory was that
the stagnation of blood in the veins caused inflammation and CNS
lesions.
If the theory about CCSVI had been correct Zamboni would have received the Nobel prize. Now no chance. |
Many
patients were fascinated by this procedure and the MS doctors also
took notice. Primarily MS doctors were not as fascinated as the
patients and meant that the obtained results could be due to the
placebo effect. Lots of patients got irritated and formed CCSVI
associations which campaigned for studies, but many patients meant
that no further studies were needed and wanted that the procedure
should be accepted with the results Zamboni had and that this was
enough.
Large studies of CCSVI
were done in eg Buffalo near Niagara Falls. Reports showed that the
condition existed but not only in MS patients. Moreover, it was
hardly more common in MS patients.
The largest pressure
group was the forum This is
MS formerly a forum to discussing everything about MS from the
western medicine to alternative medicine but now all was CCSVI. One
could say that the forum were taken over by the CCSVI debate and r
there seems to be more posts about CCSVI than all the other posts
together, more than 100,000 posts. Last year the interest declined
and now seems to be zero.
Now, the first
controlled study on CCSVI is presented.The investigators are the
same who made the major studies in Buffalo among others Robert
Zivadinov and BiancaWeinstock-Guttman. They were also neutral
regarding the CCSVI procedure and went in to investigate this without
bias in my opinion.
The study is small but controlled. 19 people with relapsing forms of MS. 9 people undergoing vascular surgical angioplasty and 10 underwent a sham procedure. There were no complications with the procedure. They found no lasting improvement in the group receiving a genuine expansion. But 5 out of 9 in the group which underwent the genuine procedure had increased disease activity on MRI compared to 2 persons of 10 in the other group.

A small study but
together with the earlier results it is time to put the CCSVI into
the garbage. If this is a study about a drug to be this would be the
consequence. It is a pity no such study was done in the beginning.
This is valuable
knowledge about CCSVI but also about other alternative cures which
are not studied enough.
