Sorry if I missed it, so everyone feel free to send me back to do my homework.
As far as I have seen, you are the only Dr that specifically uses the IVUS. From my quick research (ie the Wiki) I can see how significant a difference it would make with stenosis caused by fatty deposits etc.
Have you found any explicit lesions that you only treated because of the IVUS, that looked perfectly OK by catheter? Most lesions / stenosis discussed in my reading have been physical "deformities" and/or blockages of the veins themselves, and not due to a build-up on the vein wall.
I can certainly see how the IVUS would be invaluable to review a previously placed stent.
PS: who taught you to touch type!
you have been prolific.
it is somewhere in the prior 100 pages
ivus simply bounces sound off the wall of the interior of the veins and records the reflections of sound.
its main indication to date is in assessing coronary artery plaque. Those patients have atherosclerosis. . this does not mean that the test is good only for atherosclerosis
My use is not yet described. Getting shut down prevented me from having the number of cases that I felt i needed in order to publish.
Funny, after all the years of competition, i just posted my ideas before publicatoin....
it is extremely useful in
1. detecting particlly duplicated IJV
2. documenting stiff or fused valve leaflets
3. measuring stenosis is most accurate
4. proving that narrowings in the mid and upper jubular veins are physiologic not stenotic
