what meaning do we use for venogram?

Postby frodo » Sun May 16, 2010 11:50 pm

There are at least two meanings for venogram:

- invasive catheter venogram
- X-ray venogram, also considered invasive

I have read posts about both. Which one is the one advocated by Zamboni? Is there any publication speaking about it? Where is said that a venogram is the "gold standard" for CCSVI?

I think they do need the catheter to insert the dye in the right place, and the x-ray to be able to see it.

the procedure is all done under x-ray machine, and dye is inserted by the catheter when needed.

i do not think there is any difference, but i am not sure.

Selective Venography

Postby MarkW » Mon May 17, 2010 4:16 am

Hello All,
The procedure of Selective Venography (SV) inserts a catheter (usually via femoral vein) which is then moved into the vein to be investigated. A dye (usually iodine based) is released into the vein and an X-ray image is taken.
A clear image of the vein is usually available and any stenosis (twisting, web, membrane etc) will be visable.
SV is invasive because a catheter is inserted into a vein. There are risks of X-rays and an iodine based dye. They have been used millions of times before so unless you are pregnant or have an iodine allergy are considered a reasonably low risk.

There is a good paper on SV verses MRI in CCSVI, in the publication library, if you are research minded.

Kind regards,
