A member asked:

Can bruits change their sound as time passes?

5 doctors weighed in across 2 answers

Yes: Bruits can change their sound depending on the degree of blockage. In the carotid arteries, for example, as a blockage is almost complete ( > 90%), the bruit actually goes away! this is why a bruit is not the best way to evaluate someone for carotid disease. An ultrasound is much more accurate!

Dr Brown and 2 doctors agreed
