Dr. Sclafani,

Concerning left IJV only.

What if little to no flow in the left IJV is noted via MRV (left side drainage primarily a facial vein & vertebral plexus), the doppler shows a septum and stenosis in the left IJV....what are the possible treatment scenarios in this case?

It's a paradigm shift

With periodic dilation, if you could possibly continue to increase the size of the vein, do you have a size in mind as a goal? With this vein, did you get close to that size?

Is there any rationale behind the 2-3 week interval in arteriovenous fistula maturation? Why not shorter (1 week?) or longer (2 months? 6 months?). If it could be done at a different interval, it might be more of an option for some of your travelling patients, if the benefit seemed to be there.

Fantastic images. What an opportunity for us, and any lurking MDs, to learn and see.

all good possibilities.

as always the next step is a doppler.
tell me, was ultrasound done before each angioplasty

i have recently had sent to me some images that i was told looked pretty normal. however my read was stenosis bilaterally in the jugulars and inconclusive imaging in the azygos.

unfortunately the person who sent them to me did not tell me history, just sent the images

so it is hard to answer from what you describe.

so first off the ultrasound suite for a check of the hemodynamimcs

nunzio
i am in total agreement with you on all considerations. Firstly the high pressure balloons have a long nose and it is pretty difficult to get them to go through the jugular foramen. on the other hand, the jugular vein is always smaller at the skull base than it is near the confluens.
Secondly i am terrified of dilating this segment because of the risk benefit ratio is not so obviously in favor of taking the risk.
thirdly, the dural sinus anatomy ifs highly variable and i am not sure what exactly is pathological.

my group of neuroradiologists at the hospital will soon begin a retrospective analysis of the deep cerebral veins on cta performed for stroke in non MS stroke patients. more than jugular vein anatomay, dural sinus anatomy is quite variable.

if such a procedure were justified, i would hand off to my neuro-interventional radiologist to take care of IN THE HOSPITAL with neurosurgical backup....call me chicken

put up catheter in, inflate balloon

seriously, one cannot make a strategy based upon your description. firstly mrv is not my cup of tea

secondly mostly we see hemdynamics on ultrasound rather than the anatomical derangements that i treat.

i would say that venography is first, then IVUS, then treatment depending on what these two tests show

female 18

give or take a couple of millimeters.


recuperation, elastic recoil, healing of intima?

i dont know, i will ask my colleagues



i remember my first case. i had seen about six venographic images so it was quite challenging to know what was abnormal, how significant narrowings could be, etc.
to any lurking physicians out there, welcome to the lecture hall

Who's the guy in front of you

Now that is a picture that might have a story behind it!

Unless that is your lawn...I can't quite make out the bus stop....
I liked this response.

I checked google scholar, I didn't find anything easily.

In thinking it over, if this is usually a time-pressing situation where the patients need to get onto dialysis (if it's the AVF maturation), that might be why they wouldn't do the procedures further apart in time (but perhaps it's perfectly fine to do so, in CCSVI).

The first ultrasound revealed abnormal flow in both jugulars, the following angiogram only an azygos occlusion; fixed. The second ultrasound found a stenosis on the left. Confirmed by the angiogram; fixed. Then the right, the same way. The fourth ultrasound was ok, the angiogram as well.

To be noted, the deep cerebral veins were checked only on first ultrasound.

What a GREAT pic, Dr. Sclafani!! Thanks for the smiles and Merry Christmas to you and your friends.

I would advise her to repeat the procedure. The risks of angioplasty are comparatively low and you already know that the benefits could be great. I'm no doctor so perhaps my advice is not so valuable but it sounds as though it has to be done.

It makes me very glad to hear that there were benefits in the past and that there is a good chance that the loss of benefit, probably due to restenosis, will be reversed. With ALS. Incredible. Yes, I am very pleased for your sister and I hope that she gets the benefits back.

Thanks a lot "L"
I hope that my sister get another chance, the results of previous experience was fantastic, especially swallowing ..

sara-sama, I agree with L too. If we look at CCSVI as a separate condition from MS or from ALS, it warrants treatment in its own right IMO. Your sister has been diagnosed with two disorders.

My only caution is that for whatever reason sometimes people are not getting the same results after their second procedure that they experienced after their first. I don't understand why that would be. And sometimes, they get the exact same results or better. Your sister has all of our best wishes, I hope you will keep us updated.

Thanks Cece,
I hope she can travel and repeat the catheter without risk ..
