Are there less risks with a Stent in the Azygos vein

adamt · Post by **adamt** » Wed May 12, 2010 2:18 am

... when compared to having stents in the jugular veins?

can the stent migrate to the heart or anywhere dangerous from the azygos vein?

Also, i thought as my MS affects ONLY my lower body :
- mobility - legs strength/balance/stiffness when first standing for 5 secs.
- bladder
My upper movement works fine just like a healthy person.

Is it more likely my Azygos vein is blocked and not my jugulars?

I am due for testing in the next few months.

Just wanted some opinions please

Interesting question..I would like to know too:-)

Any ideas people?

I am no medical professional but Dr Ludyga in Poland reassured me that there will be no worry about stent migration. He is the one that has been developing the stents that are used in the procedure so from what he said there is very little chance of stents migrating and the results fro Poland prove this!!!

thanks for the reply badger.

Does anyone else know?

I think Dr. Zamboni even endorses the use of stents in the Azygos vein, so it must be fairly safe.

Hello Salvatore24
I heard Prof Zamboni on 14 April 2010 say:
Use angioplasty (venoplasty) and repeat it re-stenosis occurs.
You will find the news conference mentioned on this site and can listen for yourself.
Kind regards,

i thought balloon angiolasty was the preffered option with most surgeons but i thought stents would be safe in the azygos vein,

can stents migrate to dangerous places like the heart from the azygos vein?
is there a clear pathway to the heart?

My own feeling is that stents are not to be preferred anywhere, but rather the azy than the IJVs. There is a straight path (pretty much) from the IJVs into the vena cava, and from there to the heart, whereas, the azygos has an arch as it enters the vena cava, and the stent would have to negotiate that bend. I would think also, that the azy. is a much more "protected" location than the IJVs, and less subject to flexing, etc.

however, isn't the azygous also the least likely to re-stenose, making the need for a stent less likely? Or are they seeing a lot of patients failing even the initial round of balloon angio?

Yes with me, Dr Ludyga tried the balloon first of all but it closed over almost immediately, so he placed a stent there and I have no problems with it at all.

I have the video of the procedure and it is obvious that the vein closes over.

I also believe that as is happening in Poland, will eventually replicated around the world. Dr. Zamboni does not want to advocate the use of stents due to the problems that could occur from this, as what happened at Stanford, but in the long term that will be the way to go.

If you look at the results from Poland you will see that Venoplasty is always attempted first of all and if this is unsuccessful then a stent is then used. There is 100% success rate with the use of stents in Poland and if you are booked for an appointment there you will soon be reassured that these Dr's know what they are doing.

I have stent in azygous. On the operating table, he found stenosis. I could see there was hardly any blood flow. He ballooned, it collapsed straight after. He tried again a few times, it would not stay open!
He asked about stent, I said yes. Normal flow was restored.

It is not always a choice to have stents or not to have stents. It is not always that ballooning will work at all.

But I was under the impression that it was a low chance for azygous to restenose, if venoplasty was sucessful. Dr. Petrov in Bulgaria said he had showed my operation to the Italian professor. I assumed it was zamboni he was talking about, I did not ask.

Im kind of against azygous stenting.

angio works 95% of the time there.

its a pretty dangerous place close to the heart for anything else.

But the azygos is not on direct path with the heart; it's parallel to it. In the shown image; the right jugular is the most scary; with a boulevard open right in front to the heart (migration).

thanks for the diagram

i would of thought the azygos vein goes all the way down the spine, not just half way??

My symptons are ONLY lower body:
Mobility - leg strength, stiffness in legs , balance (this is brain tho)
Bladder

As i had a lesion in my lower spine (and some in brain),So surely its likely i have a blocked Azygos right?

No Adamt not at all.

Think of the vascular system as a series of connected hoses carrying water - each hose of different sizes. The jugulars being big veins (hoses). The rest of the body being smaller veins (hoses). Then try to connect them all and make it a closed loop circuit back through a pump (the heart).

Let's say you kink the two big hoses (jugulars). This will put immense pressure on the rest of the system all the way throughout. So an unintended consequence could be veins in other areas being over worked in the central nervous system and as a result of overwork iron/deoxygenated blood is forced through them more regularly ... so a lesion develops. Meanwhile the azygos may be clear ... it's just that it's overworked and can't keep up with what should be flowing through the jugulars.

Long analogy to say not necessarily.
