Many carotid bruits are discovered incidentally in an otherwise asymptomatic patient. FMD within the extremities may cause claudication or may be detectable by bruits. Less common symptoms are artery sounds (bruits), or ringing in the ears (tinnitus). Auscultation can be performed upon the skull to check for intracranial bruits. Bruits heard in the epigastrium that are confined to systole are considered normal. Bruits can be present in case of renal or visceral arterial stenosis.
