Does the Azygos have a high or low restenosis rate?
Does the Azygos have a high or low restenosis rate?
Ive tried searching the forums but cant find a specific title on this,
I think i read somewhere earlier in the year saying how the Azygos is less prone to restenosis
is this true?
will ballooning alone of the azygos be sufficient for long term dilation?
have there been many cases of azygos restenosis?

The rate of a restenoses in the V. azygos is very low, about 4%. Check out the "Bologna protocol"

I've heard that the azygous is less likely to restenose, and Dr. Zamboni has at least one paper showing this, but I have my doubts. (Sorry, dan, nothing personal ;) ) But why would the azygous vein be different than the other veins? If it's a valve malformation, that's just as likely to pop back out.

Bologna protocol by J. Beal: http://www.facebook.com/note.php?note_i ... 210&ref=mf
Dr. Roberto Galeotti, Azienda Ospedaliero- Universitaria di Ferrara, vascular surgeon speaks as to the results of the endovascular Liberation treatment in an open label CCSVI study.: “….The azygos vein had a 4% rate of restenosis at 18 months- the only case was a retwisting. The jugular veins had a rate of 47% of restenosis at 18 months. The team is considering a redilation of the IJVs using open neck surgery or stents….”
I've read that Dr. Zamboni and Dr. Galeotti found that the azygous was not restenosing, but I don't understand the reasoning for it.
Perhaps they were treating more of the membraneous types of CCSVI in the azygous.
With the azygous being smaller, perhaps their 10 mm balloon size did a better job of breaking the "annular constriction" in the azygous that the 10 mm balloons did in the IJVs.
