Does graft have bruit and thrill?

What’s the difference between a bruit and a thrill?
A bruit is the auscultated equivalent of the thrill and has the same significance. A thrill felt at the carotid artery may signify aortic stenosis, as the vibration is transmitted through the tissue from the second intercostal space. (Bickley et al., 2021).
What is the sound of a bruit?
