User:It's gonna be awesome/abdominal murmurs

Abdominal murmur aka abdominal vascular sounds,  abdominal bruits , abdominal auscultation, systolic murmur heard over abdominal aorta. is serviceable in aiding in the detection of an abdominal aneurysm and useful for the detection of bowel sounds and sometimes an enlarged spleen gives rise to a blowing murmur. Previously, aortic aneurysm, venous hums and arteriovenous fistulas were assumed to be the only sources of vascular murmurs. The knowledge that a murmur can be produced by an enlarged spleen has been resurrected. This is a soft, long, but never continuous, systolic murmur. A study showed by phonocardiographic tracings that the murmur is not transmitted from the heart. In his view, the murmur occurs in the enlarged splenic sinuses. They are wider than the incoming artery and efferent vein, thereby causing a turbulence similar to a small aneurysm. The diagnostic signiflcance of this sign is small, since it occurs only in greatly enlarged and easily palpable spleens and does not add new information.

It can be a warning sign of renal artery disease in Hypertension.
