Abdominal bruits. Clinical and angiographic correlation
JAMA
|June 23, 1975
Summary
Abdominal auscultation detected bruits in 21% of patients. Epigastric bruits were often linked to celiac artery stenosis, while renal artery stenosis had a lower bruit correlation.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Internal Medicine
Background:
- Abdominal bruits detected during auscultation can indicate underlying vascular pathology.
- Celiac artery stenosis and renal artery stenosis are significant conditions affecting blood flow.
Purpose of the Study:
- To correlate findings from abdominal auscultation with abdominal angiograms.
- To investigate the incidence and causes of abdominal bruits, particularly in relation to celiac and renal artery stenosis.
Main Methods:
- Abdominal auscultation was performed on 503 patients.
- Results were correlated with abdominal angiograms to confirm vascular findings.
- Incidence of bruits was analyzed in relation to specific arterial stenoses.
Main Results:
- Bruits were heard in 106 (21%) of patients.
- The majority of bruits were epigastric, primarily due to celiac artery stenosis (often extrinsic compression).
- 27% of patients with renal artery stenosis/occlusion had bruits, but often with confounding factors like celiac compression.
Conclusions:
- Abdominal auscultation is a useful screening tool for vascular abnormalities.
- Celiac artery stenosis is a common cause of epigastric bruits.
- Bruits in renal artery stenosis are less common and may be multifactorial.

01:15Heart Sounds
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...

01:25Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.

01:25Cardiovascular System Abnormal Findings II: Auscultation
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:22Nursing Assessment of the Genitourinary System III: Percussion and Auscultation
The genitourinary system maintains the body's fluid balance, waste excretion, and overall homeostasis. Proper assessment is essential for early detection of disorders, with percussion and auscultation integral to this evaluation. These methods help identify signs of kidney or bladder issues and provide important diagnostic clues.Percussion for Kidney TendernessPercussion is used to assess tenderness and detect kidney and bladder abnormalities. A common method for determining kidney tenderness...
