Overview

An abdominal bruit is a murmur heard when the diaphragm of stethoscope is placed over the spleen, renal arteries, or abdominal aorta. It is often indicative of partial occlusion of a vessel, as can be observed in renal artery stenosis or atherosclerosis of the abdominal vasculature.

Diagnosis

Physical Examination =

Abdomen

  • May have palpable thrill in addition to the murmur.

Laboratory Findings

MRI and CT

  • CT of abdomen may be helpful in evaluating underlying pathology.

Echocardiography or Ultrasound

Other Imaging Findings

Angiography

Other Diagnostic Studies

  • IV urography or radionuclide nephrograms will show differences in kidney perfusion with stenotic artery
