No data  exist on the quality of bruits as a means for quantifying the degree of stenosis.  We therefore conducted a prospective observational study to investigate the  sensitivity and specificity of femoropopliteal auscultation, differentiated on  the basis of bruit quality, to detect and quantify clinically relevant stenoses  in patients with symptomatic and asymptomatic peripheral arterial disease  (PAD).\n        METHODS:  Patients with known chronic and stable PAD were recruited in the outpatient  clinic. We included patients with known PAD and an ankle-brachial index (ABI)  &lt;0.90 and\/or an ABI \u22650.90 with a history of lower limb revascularisation.  Auscultation was performed independently by three investigators with varied  clinical experience after a 10-minute period of rest. Femoropopliteal lesions  were classified as follows: normal vessel wall or slight wall thickening  (&lt;20%), atherosclerotic plaque with below 50% reduction of the vessel lumen,  prestenotic\/intrastenotic ratio over 2.5 (&lt;70%), over 3.5 (&lt;99%) and  complete occlusion (100%).\n        RESULTS:  Weighted Cohen\u2019s \u03ba coefficients for differentiated auscultation  were low in all vascular regions and did not differ between investigators.  Sensitivity was low in most areas with an increase after exercise. The highest  sensitivity in detecting relevant (&gt;50%) stenosis was found in the common  femoral artery (86%).\n        CONCLUSION:  Vascular auscultation is known to be of great use in routine clinical practice  in recognising arterial abnormalities. Diagnosis of PAD is based on various  diagnostic tools (pulse palpation, ABI measurement) and auscultation can  localise relevant stenosis. However, auscultation alone is of limited  sensitivity and specificity in grading stenosis in femoropopliteal arteries.  Where PAD is clinically suspected further diagnostic tools, especially colour-coded  duplex ultrasound, should be employed to quantify the underlying lesion.<\/jats:p>","DOI":"10.4414\/smw.2013.13761","type":"journal-article","created":{"date-parts":[[2013,4,17]],"date-time":"2013-04-17T06:29:02Z","timestamp":1366180142000},"page":"w13761","source":"Crossref","is-referenced-by-count":1,"title":["Predictive  value of auscultation of femoropopliteal arteries"],"prefix":"10.57187","volume":"143","author":[{"given":"Carla","family":"Kaufmann","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincenzo","family":"Jacomella","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ludmila","family":"Kovacicova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Husmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert\u00a0K.","family":"Clemens","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph","family":"Thalhammer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatrice\u00a0R.","family":"Amann-Vesti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"36756","published-online":{"date-parts":[[2013,2,24]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1654\/2186","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1654\/2187","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1654\/2186","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T04:21:51Z","timestamp":1755231711000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/1654"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,2,24]]},"references-count":0,"journal-issue":{"issue":"0910","published-online":{"date-parts":[[2013,2,25]]}},"URL":"https:\/\/doi.org\/10.4414\/smw.2013.13761","relation":{},"ISSN":["1424-3997"],"issn-type":[{"type":"electronic","value":"1424-3997"}],"subject":[],"published":{"date-parts":[[2013,2,24]]}}}
