Zivadinov proves Zamboni’s “CCSVI” does not exist
Posted by Colin Rose on January 15, 2011
Almost a year ago at a much heralded news conference Dr. Robert Zivadinov, a Buffalo-based early disciple of Paolo Zamboni, claimed to show some difference in the presence of venous flow patterns in the heads of MS patients compared to controls using special Doppler ultrasound techniques that had never been validated. He never published the details of this study and has apparently abandoned ultrasound in favour of MRI venography which gives an overall picture of venous flow patterns in all head and neck veins. Zivadinov has now published a well-blinded study using MRV in MS patients and healthy controls which shows no difference in venous flow patterns in the two groups. There are almost blocked internal jugular veins in some MS patients and some normal people. But such blockages are insignificant because of the extensive collateral veins and the emissary veins connecting intra- and extra-cerebral venous circulations, as I described in my original response the Zamboni hypothesis.
I quote from the Discussion section of the paper: “We did not find significant differences between MS patients and HC subjects or between RR and SP MS patients in regard to collateral circulation. This is indeed an important finding because it does not support collateral circulation as a compensatory mechanism of CCSVI.” Such “abnormal” collateral flow was a crucial part of the Zamboni hypothesis.
As I said in response to Zivadinov’s first “study” of “CCSVI”, real scientific discussion is not conducted by news conference. Those who thought otherwise should now be convinced that only publications in respected journals following the time-honoured format for scientific communication are worthy of consideration.
With this paper and at least three others showing the same result, we now have overwhelming evidence that “CCSVI” is a fantasy, concocted by Paolo Zamboni, a varicose vein surgeon who convinced himself that he could “liberate” his wife from MS by dilating her neck veins. To date, at least $one billion has been wasted on this myth by desperate patients, granting agencies and governments. No further attention or money should be directed at this farce. All MS patients should refrain from paying for “liberation”, a very profitable scam based on the “CCSVI” myth.
