The grade of deep venous insufficiency (Grades 1-4) was estimated in a blinded fashion with phlebography and duplex technique. Agreement occurred in 15 of 23 lower extremities. Discrepancies were found particularly in patients with minor degrees of reflux. The patients with reflux below the knee according to phlebography were also identified with ultrasonography. The authors found duplex scanning to be an accurate method of evaluating deep venous valvular function. With duplex\u2014but not with phlebography\u2014it was also possible to diagnose isolated lower extremity valvular insufficiency.<\/jats:p>","DOI":"10.1177\/000331979004100607","type":"journal-article","created":{"date-parts":[[2007,11,26]],"date-time":"2007-11-26T17:46:29Z","timestamp":1196099189000},"page":"463-468","source":"Crossref","is-referenced-by-count":22,"title":["Assessment of Deep Venous Incompetence: A Prospective Study Comparing Duplex Scanning with Descending Phlebography"],"prefix":"10.1177","volume":"41","author":[{"given":"Stefan","family":"Rosfors","sequence":"first","affiliation":[{"name":"From the Department of Clinical Physiology, St. G\u00f6ran's Hospital and the Karolinska Institute, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stellan","family":"Bygdeman","sequence":"additional","affiliation":[{"name":"From the Department of Clinical Physiology, St. G\u00f6ran's Hospital and the Karolinska Institute, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eva","family":"Nordstr\u00f6m","sequence":"additional","affiliation":[{"name":"From the Department of Diagnostic Radiology, St. G\u00f6ran's Hospital, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1990,6,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(86)90381-2"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(86)90192-8"},{"key":"atypb3","first-page":"238","volume":"10","author":"Sandager G.","year":"1986","journal-title":"Bruit"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800750419"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.137.1.7422863"},{"key":"atypb6","unstructured":"Kistner RL: Transvenous repair of the incompetent femoral vein valve.
