This study was done to investigate the reliability and reproducibility of VAFI as quantitative pattern. Patients and methods: In 43 patients with varicose veins C<jats:sub>4\u20136<\/jats:sub> E<jats:sub>P<\/jats:sub>A<jats:sub>S,D,P<\/jats:sub>P<jats:sub>R<\/jats:sub> (PVV), 40 with postthrombotic syndrome C<jats:sub>4\u20136<\/jats:sub> E<jats:sub>S<\/jats:sub>A<jats:sub>S,D,P<\/jats:sub>P<jats:sub>R,O<\/jats:sub> (PTS) and 48 healthy volunteers volume flow in the common femoral vein (VFV) and artery (VFA) were measured by duplex. Division of VFV by VFA calculated VAFI. VAFI-measurement was repeated 5 times at an interval of ten minutes in 63 subjects (23 PVV, 20 PTS, 20 healthy) and it was performed at three different days in 68 subjects (20 PVV, 20 PTS, 28 healthy). Results: Mean VAFI \u00b1 standard deviation was 1.39 \u00b1 0.26 in PVV, 1.42 \u00b1 0.26 in PTS and 0.93 \u00b1 0.13 in healthy veins (p &lt; 0.001). VAFI remained stable and significantly increased (p &lt; 0.001) in PVV and PTS compared to healthy veins during 40 minutes and also within three different days. Conclusion: The venous-arterial flowindex VAFI is a reproducible pattern of the hemodynamic severity in venous insufficiency. <\/jats:p>","DOI":"10.1024\/0301-1526.32.4.199","type":"journal-article","created":{"date-parts":[[2006,1,31]],"date-time":"2006-01-31T12:26:21Z","timestamp":1138710381000},"page":"199-203","source":"Crossref","is-referenced-by-count":8,"title":["Die Reproduzierbarkeit des veno-arteriellen FlowIndex f\u00fcr die quantitative Erfassung des h\u00e4modynamischen Schweregrads von ven\u00f6sen Erkrankungen"],"prefix":"10.1024","volume":"32","author":[{"family":"Kahle","sequence":"first","affiliation":[{"name":"Division of Phlebology, Dermatological Medical Center, University of Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Hennies","sequence":"additional","affiliation":[{"name":"Division of Phlebology, Dermatological Medical Center, University of Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Bolz","sequence":"additional","affiliation":[{"name":"Division of Phlebology, Dermatological Medical Center, University of Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Pritsch","sequence":"additional","affiliation":[{"name":"Institute of Medical Biometry and Informatics, University of Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"101","container-title":["Vasa"],"original-title":[],"language":"de","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0301-1526.32.4.199","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,8]],"date-time":"2022-05-08T10:01:09Z","timestamp":1652004069000},"score":1,"resource":{"primary":{"URL":"https:\/\/econtent.hogrefe.com\/doi\/10.1024\/0301-1526.32.4.199"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,11,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2003,11,1]]}},"alternative-id":["10.1024\/0301-1526.32.4.199"],"URL":"https:\/\/doi.org\/10.1024\/0301-1526.32.4.199","relation":{},"ISSN":["0301-1526","1664-2872"],"issn-type":[{"value":"0301-1526","type":"print"},{"value":"1664-2872","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,11,1]]}}}
