Bruit ( or, from French, 'noise'), also called vascular murmur, is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.
In the medical field of cardiology, a stethoscope is used to detect heart sounds and bruits, which are due to turbulent blood flow. In normal individuals, heart sounds are a product of turbulent flow as heart valves close. However, in some conditions turbulent flow can be audible due to other reasons, some of them pathological. For example, in advanced atherosclerosis, bruits (and therefore turbulent flow) can be heard in some vessels that have been narrowed by the disease process.

Carotid artery stenosis

Stroke, carotid artery stenosis
Less common symptoms are artery sounds (bruits), or ringing in the ears (tinnitus).

Aortic aneurysm

A bruit may be heard from the turbulent flow in the aneurysm.

Median arcuate ligament syndrome

Median arcuate ligament syndrome, celiac artery stenosis – external compression
The abdominal pain may be related to meals, may be accompanied by weight loss, and may be associated with an abdominal bruit heard by a clinician.

Tinnitus

Tinnitus – a symptom which may be caused by a cranial artery bruit
Pulsatile tinnitus can be a symptom of intracranial vascular abnormalities and should be evaluated for irregular noises of blood flow (bruits).

Fibromuscular dysplasia

Fibromuscular dysplasia
The main symptoms associated with renal FMD are secondary hypertension and bruits that can be heard with a stethoscope over the abdomen or flanks.

A carotid bruit is a vascular murmur sound (bruit) heard over the carotid artery area on auscultation during systole.

Souffle
It is particularly used to describe vascular murmurs or transmitter heart sounds which occur during pregnancy, either from the uterus and breasts of the mother, or from the fetus.

Auscultation

The bruit may be heard ("auscultated") by securely placing the head of a stethoscope to the skin over the turbulent flow, and listening.

The bruit may be heard ("auscultated") by securely placing the head of a stethoscope to the skin over the turbulent flow, and listening.

Systole

systolicsystolic pressureventricular systole
Most bruits occur only in systole, so the bruit is intermittent and its frequency dependent on the heart rate.

Fever

Anything increasing the blood flow velocity such as fever, anemia, hyperthyroidism, or physical exertion, can increase the amplitude of the bruit.

Anemia
