Good morning! I had hoped you would continue these reports.

This does seem to show quite a bit of information about the valves that may be difficult to get in another fashion. Some discussion about cross sectional areas and ultrasound viewed pathology was also included.
Did the other IRs in the audience seem to share this view?
We have discussed IVUS a great deal here on this forum and I was able to see the patient day version of his IVUS talk on Friday. With the cross sectional areas, he showed the difficulties when trying to measure the vein by flouroscopy, since veins are oval shaped, and you will get a different measurement if you are looking at them straight-on or from a different angle. So some precision is lost if measuring through flouroscopy as compared to IVUS and one question is how important is that precision? How vulnerable are these veins to damage, if the balloon is oversized? Or to undertreatment, if undersized.
He was also going to share what he has been seeing of webs on IVUS, which he has treated in some patients, and you really don't hear much talk about webs but they were discussed in Zamboni's original work as among the intraluminal abnormalities that make up CCSVI.
