Left IJV flow slowed by downstream compression

So due to slow flow or sometimes reversed flow in the left jugular vein which occur secondary to compression of this left innominate vein by the aorta as the vein passes under the sternum, there is artifactual high signal in the left jugular vein.

Hmmm. New target of investigation if flow isn't optimal after PTA?

Are we stenting the innominate vein? Anybody even checking for this compression?

Some pwCCSVI have been ballooned or stented in the innominate vein. I don't think it's high on the radar but it's on there. Since it's usually a compression, ballooning is not expected to be durable (the compression continues to compress). Stent migration is a real concern. If the brachiocephalic artery becomes tortuous (enlarged/convoluted) with age, it can be what it is compressing on the innominate. Another reason to stop with this whole growing older thing and grow younger instead.

I did it again. Cece posted about this years ago. Better info in her thread.

Nahh I love seeing previous research discussed again.

There was a live CCSVI case on youtube (not sure where) from one of the conferences. Probably ISNVD? Anyway the doctor involved who may have been Polish ballooned the jugulars and when flow wasn't good, he ballooned the innominate vein a couple times, although he had not identified a stenosis there. That was part of my introduction to the idea of ballooning a vein as a way to diagnose the vein; an IR can balloon the length of the azygous and discover it is stenosed because a waist or squeezed spot shows up on the balloon. But then it seems this is not the best way to diagnose stenoses because random ballooning can lead to vein injury.

Click on the last link titled "Brachiocephalic compression: should it be treated?" in the section "Related topics" at the bottom of the page; other compression topics are also listed. (posting from hotel room)
