This wouldn't give you volume. For that you need length x area or n*π*r². In addition, cross sectional area is used for the comparison instead of something like the radius or diameter since the veins are often not perfect circles.

Hope this helps, NHE

I think the 1eye misunderstanding come from the fact that n represent the greek letter Pi or 3.14 which look like an eglish alphabet "n" or TT, therefore r*r*Pi is the area of a circle.

thank you for clarifying that for everyone. I was as confused by oneeye as others were. I was going to instruct that the formula made no sense as we are concerned with area, not volume, but you did it for me.

Some of the ultrasound units automatically calculate the area from the measurements. Often it is quite clear that the area of the vein is larger or smaller comparing upright and supine by simply eyeballing it, a pun both of you can relate to

sorry to bother you with this question but I have tried to get an answer from my gp who didnt have a clue about 'sticky blood syndrome' tested me for facor V and told me I had no problem.

You had advised me sometime ago to have my blood tested for this condition before I would attend for the ccsvi treatment as my brother suffers from this. I got the results about five weeks ago orderd by my work/college gp who thinks there is an issue with it and to bring the result to my next appointment with my neuro which is not until end of august...

I havent got a clue what kind of test they are only that they are for coagulation. They were ran in a lab in a university hospital in Ireland.

Antithrombin 120.0 u/dl (79 - 131)
Protein C 120 u/dl (64 - 128)
Free Protein S 146.0 u/dl (65 - 124) H
APC resistance 2.9 (2.1- 4.0)
Lupus Inhibitor Negative

What do you think. I suppose I am ever hopeful as I have not got a proper diagnosis and I know that sitcky blood can mimic ms. Although my brother has sticky blood and a missing or undeveloped vein into his kidney and both conditions contrived to cause dvts in both legs. (he was diagnosed in London)

Thank you so much for your time.
Regards

your lab results are listed first, followed by the normal values of the lab that did your testing in parentheses. I don't see any lab results of a deficiency that would lead to a "sticky blood" disorder.

Looks like time to look into a Doppler ultrasound to screen for CCSVI and if positive to find someplace to do a catheter venogram.

I also faxed over the meeting January 26th to Dr. Sarah, (the IR who read the first MRV) who said they needed time to investigate CCSVI before they use the contrast dye. Friday I learned she will be out of the country INCLUDING NEXT WEEK! Perhaps it will be the chairman of the diagostic imaging department at the Hospital who needed extra time.

The question is: My PCP ordered the tests at my request, so should I talk with the IR (who will be reading them) to see if he will do Catheter Venogram GOLD STANDARD next no matter what he finds? My PC appreciates my help and will prescribe it if/when I find someone to do it. I also appreciate your intervention!

Inverted valves is all they think I have so far, but I don't trust them with stents in the veins. The more I know, the more I learn what I don't know! I'm afraid they won't listen when I ask that during the CV they use the LEFT femoral vein. I don't want to be the first unsuccessful liberation because they don't know what they're doing!

I am finding it more and more difficult to make sense or give opinions about the testing that people are describing on this site.

The more I see the results of all the testing being sent to me, the more i realize that we are moving into unchartered, unvalidated utilization of MRv and crappy ultrasound exams. Can someone point to a paper that shows that MRV correlates with catheter venograms? while many experts are trying, I am not aware of this test being validated. It seems that many patients and doctors are RELYING on an unproven expensive screening test instead of a VALIDATED inexpensive screening test like Doppler ultrasound. Worse still, many of the Ultrasound exams that people are sending me are incomplete, and do not have TCD, do not have transverse imaging, do not show the vertebral veins, do not have B-mode imaging.

I fear that we are going to validate Big Pharm's and some neurologists' objections if we don't start validating and standardizing these tests.

YES!! That's exactly what we're all hoping for - a life where our MS symptoms are not the focus.

I'm so happy for you!


I am glad for all who have shown improvements. Wonderful.

But going on with your life should include surveillance to assure that restenosis does not result in recurrence.

So can you tell me, how you are being tested for this

doppler? MRV? clinical examinations?

how often?

Who is following your progression?

Are you compliant with followup advice?

Thanks

I "stole" my question from another thread. Another feature of DrSclafani ASKS some questions.

As this is the larger thread, I wanted to ask those who have had liberation the above question.

s

Speaking for myself, i had a follow up doppler 2 weeks ago and two and a half months out of treatment. The radiologist told me my veins are actually visible this time while my collaterals are still flowing also.
He will check me on the 6 month mark again.

Having said that, i think that i will need more than that down the road as new vascular problems are constantly being found and even people who have stents placed in their jugs are being told that flow is again absent one year after...

http://www.thisisms.com/ftopict-12796.html

All in all, i am far from feeling comfortable with the follow up care available.

Hope that gives you an idea of where some of us stand.
I also hope that the research will progress quickly cause having the angio is one thing. Keep the blood flowing after that is another...

Better ivus should do the trick...

Hi Doctor S.

I've been looking through the internet and can't find a consistent answer for these:

What are the normal average diameter sizes of the external and internal jugular vein?

Is there an average or minimum amount of blood that should be going through one's noggin?

Thanks!

about 9-15 mm in diameter. The vein is really variable in size

Is there an average or minimum amount of blood that should be going through one's noggin?

Thanks!

A/C

about 1/2 ml/min per gram of brain tissue weight. This euates to about 50 ml of blood per minute per 100 grams of brain or about 750 milliliters of blood per minute.

Go Michelle!!!

Dr. Sclafani,

My MRV to be REDONE with contrast dye Tuesday but the DOPPLER should be redone? quoting you: "Worse still, many of the Ultrasound exams that people are sending me are incomplete, and do not have TCD, do not have transverse imaging, do not show the vertebral veins, do not have B-mode imaging."

All the doppler found was inverted valves ("possibly an artifact") and they didn't do it right? All I provided was Dr. Zamboni's protocol for the doppler and the MRV. My PCP prescribed a "transcranial doppler" (pat him on the back for that), so I will tell him tomorrow that I didn't get what he asked for according to MY ONLINE doctor (you).

***Please save all of us time*** (and yourself) and tell us EXACTLY what the testing prescription MUST include.

I will be contacting the technician tomorrow and will ask if the Doppler included "TCD" (transcranial doppler? right?), "transverse imaging", images of the "vertebral veins", as well as "B-mode imaging". If he says yes, I would like to send you a copy of the CD for your review to see if it's usable down the road when I find someone COMPETENT AND QUALIFIED to do the liberation procedure.

I am scheduled for August 24th (can't wait). The plan is to do Doppler ultrasounds at 3, 6, 12,18 and 24 months in my own location. Is that sufficient?

My follow-ups are at 2 months and a year. Once a year after that unless I have a problem.
MRV, meeting and questionaires. (possibly more since things are changing all of the time)
Dr. Dake and my GP.
I took Coumadin for 2 months, Plavix for 3 months and I will take an aspirin everyday for life. And I've been very compliant
