What I've seen aren't collaterals, they were definately native vertebral veins running alongside tortuous vertebral arteries. They originate from SCAs bilaterally and run the same course as a non tortuous vessel.
A new nosologic vascular pattern that is defined by chronic cerebrospinal venous insufficiency (CCSVI) has been strongly associated with multiple sclerosis. The picture is characterized by significant obstacles of the main extracranial cerebrospinal veins, the jugular and the azygous system, and by the opening of substitute circles. The significance of collateral circle is still neglected. To the contrary, substitute circles are alternative pathways or vicarious venous shunts, which permit the drainage and prevent intracranial hypertension. In accordance with the pattern of obstruction, even the intracranial and the intrarachidian veins can also become substitute circles, they permit redirection of the deviated flow, piping the blood towards available venous segments outside the central nervous system.
In the msers I have scanned, I have noted tortuosity of the same extracranial veins and arteries - mostly veins.
Have you noticed this trend?? In some I've seen, they almost looked like varicositis of the GSV.

It's a bit like being a Dentist pulling teeth though!

I wonder--does Dr. Arata refuse to treat patients who don't want the MRV? He talks about having done 2,000 CCSVI procedures, but none of those were done using IVUS because he didn't want to invest money into acquiring (purchasing or leasing) the equipment. Please correct me if I'm wrong, but doesn't $5,000 x 2,000 = $10,000,000 TEN MILLION DOLLARS??? Seems to me he could easily afford to start to use IVUS. I feel so sorry for all his patients who paid all that money and didn't receive complete procedures.

that is attempting another treatment method, non-invasive, will report as his results
come in, his patient has already been angio'd but it (good results) went away after two months.
He spent 2 hours one Saturday explaining things to me, and it made sense. Will report as it comes in.

Dr. Harris linked to an IRB that they are doing using a Volcano IVUS, which must mean they have one in the clinic now.

This is my understanding as well.
