Hi ky, I just read your post and wanted to mention that I have a bruit on my right side despite a scalenectomy I had on that side 20 years ago. I'm not sure if that's the same thing as a thrill or not, but this was seven years ago that a Dr. pointed this out to me. So my point is, even after surgery, the bruit is still there. No one ever told me it was dangerous or anything to worry about.
