That white dot (yellow arrows) is still awfully mysterious. It's hard to know if or how much a web affects flow. It is present throughout the vein.
I looked. I was mystified too, as I am very baffled by IVUS images (while being a big fan of those who can read them). Something that small might have a large surface area if it were long. Might it affect shear? Flow volume?
I can't reconcile these:

verterbral system is just as important as the internal jugular system.
Why would we not have insufficiencies there too? If there is one congenital malformation causing trouble,, as Dr. Zamboni speculated re the leg veins, why not there?

Or maybe upgrade your pay? Again with the reflux. Why can some people see it, others not, still others think it doesn't matter? Sorry Dr. S., for rhetoric and being so off-topic. You see it in most patients, don't you? Is it unusual? Why don't the valves keep it out? How can flow be bidirectional with working valves?
