Bruits occur in 4% to 20% of healthy persons. Abdominal bruits are more common in those younger than 40 years than in older persons. Characteristically, the abdominal bruit of a healthy individual is systolic, medium- to low-pitched, and audible between the xiphoid process and umbilicus.
What does aortic bruit indicate?
Bruits are blowing vascular sounds resembling heart murmurs that are perceived over partially occluded blood vessels. When detected over the carotid arteries, a bruit may indicate an increased risk of stroke; when produced by the abdomen, it may indicate partial obstruction of the aorta or…
Where do you listen for abdominal aortic bruit?
To auscultate the aorta, place the stethoscope between the xiphoid (epigastrium) and the umbilicus about two-thirds of the way down.
Do you hear a bruit with AAA?
The presence of an abdominal bruit may suggest turbulent flow which may occur with an aneurysm. The presence of pulsatile popliteal masses bilaterally may not diagnose a AAA directly but the presence of bilateral popliteal artery aneurysms may suggest an increased incidence of AAA.
What does it mean when you hear an abdominal bruit?
Bruits are vascular sounds resembling heart murmurs. Sometimes they’re described as blowing sounds. The most frequent cause of abdominal bruits is occlusive arterial disease in the aortoiliac vessels. If bruits are present, you’ll typically hear them over the aorta, renal arteries, iliac arteries, and femoral arteries.
Is bruit sound normal?
These sounds may be normal, innocent findings (i.e., a venous hum in a child) or may point to underlying pathology (i.e., a carotid artery bruit caused by atherosclerotic stenosis in an adult).
How do you Auscultate an abdominal bruit?
Begin in the right lower quadrant (RLQ), and move in sequence up to the right upper quadrant (RUQ), left upper quadrant (LUQ), and finally the left lower quadrant (LLQ). Auscultate for bruits over the aorta, renal arteries, iliac arteries, and femoral arteries.
What does a bruit and thrill sound like?

What is the difference between a bruit and a murmur?
When normal laminar blood flow within the heart is disrupted, an audible sound is created by turbulent blood flow. Outside of the heart, audible turbulence is referred to as a bruit, whereas inside the heart it is called a murmur. A pictorial representation of systolic and diastolic murmurs is below.
How do you examine abdominal aorta?
The aortic pulse can be palpated just above and to the left of the umbilicus. The width of the aorta can then be measured by placing both hands palms down on the patient’s abdomen, with one index finger on either side of the aorta. Each systole should move the fingers apart.
Where do you hear bowel sounds?
The intestines are hollow, so bowel sounds echo through the abdomen much like the sounds heard from water pipes. Most bowel sounds are normal. They simply mean that the gastrointestinal tract is working. A health care provider can check abdominal sounds by listening to the abdomen with a stethoscope (auscultation).
What does an abdominal aortic aneurysm sound like?
Diagnosis of Abdominal Aortic Aneurysms
Doctors may feel a pulsating mass in the center of the abdomen. With a stethoscope placed on the middle of the abdomen, doctors may hear a whooshing sound (bruit) caused by turbulence as blood rushes past the aneurysm.
