Strandness's Duplex Scanning in Vascular Disorders
By R. Eugene Zierler

The supraclavicular subclavian vein can be difficult to image, but a midrange transducer with a small footprint is ideal for visualizing this important segment. This is a common location for a venous stenosis as the subclavian vein curves to join with the internal jugular vein and becomes the innominate vein (see Fig. 18.4). There is often a valve in this segment that can contribute to a stenosis if the valve leaflets become fibrotic over time.

Look at that, it's in the textbook.
This is from 2009, fourth edition, so it predates the CCSVI controversy.

Extremely importantly, what are its symptoms? How is it treated? Short-term and long-term prognosis? Restenosis? How common? Associations with other diseases?

And what are the insurance codes?

[Cece]

Unless I'm reading it wrong? I thought it was talking about the valve in the internal jugular vein but now it reads as if it's the subclavian vein.
Insurance codes would be for central venous stenosis.

Lot's of CCSVI associated information and medical study's have pre-dated Dr.Zamboni's work. Thanks for providing the latest information. Well done.
