The article focuses on the importance of phonoangiography for the evaluation of arterial stenosis. Stenosis increasing uniformly and in conical shape from proximal to distal, discontinuing suddenly in the periphery, need not cause any murmurs. At the point where possible thrombotic deposits end, however, change of flow rate and pressure with the stethoscope usually produce sounds. Brief systolic, but also systolodiastolic, sounds of very different intensity are typical for arterial aneurisms, while aneurisma dissecans produces almost exclusively systolic sounds. If sounds are heard over an artery with the stethoscope without any compression, graphic reconting of this sound is recommended. Graphic recording of decrescent sounds that are audible only during part of the systole does not reveal any evidence of vascular wall changes. Holosystolic sounds recorded without compression by microphone suggest the presence of stenosis.
