Can you diagnose abdominal aortic aneurysm with a stethoscope?

Not typically: Abdominal aortic aneurysms, when large enough, can sometimes be felt by pressing on the abdomen. This feels like a very prominent pulse in the abdomen, which cannot be typically felt in most people (unless you're really thin). Sometimes an aortic aneurysm may produce a sound that can be picked up by a stethoscope, but this is unlikely and not typical at all. Consult a vascular surgeon.

No: You may hear a noise- bruit. With the scope held on the abdomen, it may bounce and with additional palpating you may detect the pulsatille mass- aneurysm. Some by exam, but since we are an obese society these days, more are found on ultrasound or ct scan.
