seeing webs on IVUS

On IVUS imaging, a web-like membrane was noted within the lumen of the vessel at the proximal region responsible for the pressure gradient (Fig. ... (C) IVUS image of proximal web after disruption by balloon angioplasty. IVUS, intravascular ultrasound. ... ... 8/abstract

If anyone has access to the full article, do the images of webs look like the bright spots we've been seeing in a few of Dr. Sclafani's images?

It's tricky because the use of the word 'web' isn't standardized, so these authors might not be talking about the same thing as we talk about here.

Applications of Intravascular Ultrasound in the Treatment of Peripheral Occlusive Disease

Jason T. Lee, MD, Tony D. Fang, MD†, Rodney A. White, MD†

Intravascular ultrasound (IVUS) has emerged as a useful and often necessary adjunct in a rising number of catheter-based peripheral interventions. IVUS catheters enable luminal and transmural cross-sectional imaging of peripheral vessels with high dimensional accuracy and provide detailed information about lesion morphology. IVUS is able to guide the optimal choice of appropriate angioplasty technique, guide the delivery of endovascular devices, and assess the immediate outcome of an intervention. In this review we discuss the role of IVUS for peripheral occlusive diseases, specifically the applicaiton of IVUS technology during percutaneous transluminal angioplasty (PTA), intravascular stent placement, crossing total occlusions, and venous obstructive disease. ... 4/abstract

another one...

These came up in a google scholar search on "webs IVUS." So there is probably mention of webs within the articles, where I cannot see it. :(

hmmmm maybe a google image search

A good number of Dr. Sclafani's images turn up there! But other interesting things too.

lol..."IVUS Made Easy"...I doubt it! 128 pages is not nearly enough.

We could use something like this, only with CCSVI IVUS images instead of coronary IVUS images, and full interactive teaching. Oh, and not password-protected!

This is so interesting to me...colorful IVUS, where the different colors show the composition of the vein and if it's fibrotic, lipidic, necrotic, calcified....

What I want to see is this colorful IVUS turned on the area of the vein where the bad valves were, after the valves have been destroyed. I am curious as to what changes have occurred to the vein wall as a result of the turbulent flow and perhaps poor oxygenation at that spot. I am curious how closely it resembles "healthy vein."

I am also curious, if the vein wall is found not to be healthy, if this is reversible. So this would mean looking at the vein with the colorful IVUS again six months or a year later on.

Just thinking out loud. It's a technology with a lot of potential.
