Dr. Alon Gitig
Cardiology 21 years experience
A sound blood makes: Bruit refers to a sound, heard via a stethoscope, of blood when it flows through a narrowed opening. As blood flows through a narrow diameter within a vessel, the velocity of flow increases and also becomes more turbulent. The importance of this sound is that, if your doctor hears it, it can signify underlying atherosclerosis--i.e. Build-up of plaque--narrowing an artery.
Dr. Otto Placik
Surgery - Plastics 35 years experience
Constructed flow: A bruit is the sound blood makes when it passes through a narrowing not unlike a wind passing through a narrow canyon. Although it may occur nearly anywhere in the body, it is typically used to refer to a narrowing of the carotid or neck arteries and implies there may be a narrowing which may be predictive if an impending stroke. When it is accompanied by a vibration, we call it a thrill.
