this would mean what dr. resulting in a negative delta (positive result). B mode abnormality noted ?

Delta CSA measures the diameter of the same jugular vein when lying down and sitting up. Normally the vein is larger lying down. One of the five criteria is that the vein is larger sitting up than when lying down.
...
There are only five findings. So unless TCD and delta CSA are done, your chances of having two of the five signs (consistent with CCSVI) are maredly reduced

what is venous thrombosis ?

what I dont understand is what veins both right ?

What is the cross sectional area ?

Some people post that there veins are 70% 80% 90% closed how do you come up with that number

this would mean what dr. resulting in a negative delta (positive result). B mode abnormality noted ?

Clotted blood in a vein.

Reflux may be present even in the absence of a stenosis, e.g. due to malformed valves, septa etc.

Assuming the vein is a cylindrical tube CSA is π*r*r

(Normal CSA, i.e above or below the stenosis – CSA where the narrowing is )/ Normal CSA

An IJV narrowing may cause reflux or a disturbance in the blood flow. B mode abnormality is suggestive of a problem in the vertebral plexus or in the azygos vein, i.e. the main drainage canal in the sitting position.

So your saying there might also be a problem in my Azygos vein and I should have it checked as well

You as patients have an obligation to yourselves to seek out BEST practice. However that is not what is going on. You are seeking out AVAILABLE practice.

i am not sure that a tidal wave is a healthy thing. I am deeply concerned when a patient is told that there catheter venogram shows a normal right IJV and an occlusion of the left IJV but I see an abnormal right IJV and a catheter venogram of the vertebral vein is called an occluded IJV. Some neurologists are smirking about this stuff

You will be happy to hear that the first CCSVI Symposium, put together just a few weeks ago is getting a fair amount of interest, thanks in part to your efforts. Yesterday a CCSVI treating physician from Bulgaria reserved to come to the meeting in Brooklyn! Keep up the good work. You will accomplish much by encouraging doctors to be involved in the educational process.

Hello Dr.,
I sent you a PM, but wasnt sure if you would check that. I have had a venogram and angiogram (both catheter) and no stenosis was found. Should I have someone else looked at the films.. or should I have another test done?
I would love to hear from you.

Thanks again. One final question (I promise.) If it does turn out to be the problem and venoplasty isn't an option would an operation be possible to fix the problem?

I think that I shall get in touch with my cardiologist.

Thanks again for taking the time for us, it is so very good of you.

CeCe,
I hate to sound stupid, but I don't know what veins were checked! I just know they went in both sides of the groin and up through the neck and head. The IR who did it had read up on Zamboni's research; however, he did tell me that he had done the procedure on one other person and had found no stenosis on them as well.

Dr. S

Well dr I got my results from the Doppler and was wondering if I post what it says can you please help me try to understand it. I know that I have CCSVI But dont understand in what way

Findings Right Jugular
The cerebral venous outflow appears patent with no evidence on venous thrombosis. Venous Insufficiency was evident with reflux in the internal Jugular vein at 0 and 90 degrees. The cross sectional areas of the internal jugular vein at 90 degrees is larger than the cross sectional area at 0 degrees resulting in a negative delta (positive result). B mode abnormality noted


Findings left Jugular
The cerebral venous outflow appears patent with no evidence on venous thrombosis. Venous Insufficiency was evident with reflux in the internal Jugular vein at 0 and 90 degrees. The cross sectional areas of the internal jugular vein at 90 degrees is larger than the cross sectional area at 0 degrees resulting in a negative delta (positive result). B mode abnormality noted

CONCLUSION
Venous reflux/insufficiency is noted in the internal jugular veins on the right and left at 0 and 90 degrees. positive values for cross sectional area of the internal jugular veins on the right and left B mode abnormalities noted bilaterally.
Criteria met for CCSVI:3/5

Any help would be appreciated Dr.

thanks a head of time

the vein is clotted and has no blood flow


I do not understand this question. try again


the vein is seen end on and looks like something like a circle. a measurement is made of the area of the circle.



you measure the diameter or the cross sectional area of the narrowed area and divide it by the diameter or cross sectional area of the normal vein




normally subtracting the cross sectional area of the vein standing up from the cross sectional area of the vein lying down equals a positive number.
The zamboni criteria is present if the cross sectional area sitting up is greater than when lying down. That gives a negative delta



This means that something abnormal is seen on the views of the vein, like a stenosis, a valve, a septum, a web.



my pleasure. hope you understand

possibly. but i would get a second opinion from someone.
too many misses

send me the images and i will look at it

it helps me stay in the game
