"The hypothesis has generated optimism among people with MS regarding effective treatment options but has received skepticism by the majority of medical community"
This seems inaccurate to me. The majority of the medical community is unaware. The reactions of neurologists are certainly skeptical and resistant, but vascular specialists are much more intrigued and interested in further research.
"Most of the venous problems in MS patients have been reported to be truncular venous malformations, including azygous stenosis, jugular defective valves and jugular veins aneurysms. Innominate vein and superior vena cava have also been reported to contribute to CCSVI."
Aneurysms?? No aneurysms.
"The original results have been replicated in a second study, but others have found CCSVI to only occur in 20% of MS patients."
This makes it sound like more than one study has found results in 20% of MSers, when it was just one...the use of the plural 'others' should be singular 'another'.
You are right, this all slants negative toward CCSVI.
