Bruit
Bruit (/bruːt/; from French, meaning "noise") is a term used in medicine to describe a sound, usually abnormal, heard through a stethoscope.
Pronunciation
The word is pronounced as "broo-EE", with a silent 't'.
Etymology
The term 'bruit' is derived from the French word for 'noise'. It was first used in the medical context in the 19th century to describe the abnormal sound heard in the arteries due to turbulent blood flow.
Definition
A bruit is an audible vascular sound associated with turbulent blood flow. Although bruits can be heard in normal individuals, they are often associated with vascular disease, such as atherosclerosis or aneurysm.
Types of Bruit
There are several types of bruits, including carotid bruit, renal bruit, and abdominal bruit. Each of these is named for the location in the body where the sound is heard.
Carotid Bruit
A carotid bruit is a sound heard over the carotid artery in the neck that may indicate narrowing or blockage of the artery.
Renal Bruit
A renal bruit is a sound heard over the renal artery that may indicate narrowing or blockage of the artery.
Abdominal Bruit
An abdominal bruit is a sound heard over the abdominal aorta that may indicate an abdominal aortic aneurysm.
