There are 47 countries in the world that recognize CCSVI as a true entity. In terms of the science, Dr. Zamboni did a study. He looked at 65 patients and found that many patients with MS had significant venous anomalies. He treated 65 patients and many of them saw significant improvement in symptoms.
I read his paper. I realize what his paper says. However, I also spent several days with Dr. Zamboni, and he subsequently has done a total of 130 to 135 patients, finding there is significant improvement in the symptom complex in these patients.
The science is also supported by the work of Dr. Simka in Poland, who has done upwards of 300 patients, similarly finding improvement.
If you take the study to Stanford University, Dr. Dake did 40 patients. He was doing a different procedure with those 40 patients. He was stenting the veins in the patients, which is not supported by Dr. Zamboni or his work. He does not stent or believe in stenting. The problems that Dr. Dake encountered were stent problems. That is, the stent migrated and resulted in a cardiotomy. And the other problem was a post-op stroke that the patient's family denies had anything to do with the procedure itself.
