Among the different tests used in the <jats:styled-content style=\"fixed-case\">VA<\/jats:styled-content> domain, color Doppler ultrasound (<jats:styled-content style=\"fixed-case\">CD<\/jats:styled-content>\u2010<jats:styled-content style=\"fixed-case\">US<\/jats:styled-content>) plays a key role in the clinical work\u2010up. At the present time, three are the main fields of <jats:styled-content style=\"fixed-case\">CD<\/jats:styled-content>\u2010<jats:styled-content style=\"fixed-case\">US<\/jats:styled-content> application: (i) evaluation of forearm arteries and veins in surgical planning; (ii) testing of <jats:styled-content style=\"fixed-case\">AVF<\/jats:styled-content> maturation; (iii) <jats:styled-content style=\"fixed-case\">VA<\/jats:styled-content> complications. Specifically, during the <jats:styled-content style=\"fixed-case\">AVF<\/jats:styled-content> maturation, <jats:styled-content style=\"fixed-case\">CD<\/jats:styled-content>\u2010<jats:styled-content style=\"fixed-case\">US<\/jats:styled-content> allows to measure the diameter and flow volume in the brachial artery and calculate the peak systolic velocity (<jats:styled-content style=\"fixed-case\">PSV<\/jats:styled-content>) of the arterial axis, anastomosis and efferent vein, to detect critical stenosis. The borderline stenosis, revealed by the discrepancies between access flow rate and <jats:styled-content style=\"fixed-case\">PSV<\/jats:styled-content>, should be followed up with subsequent tests to detect progression of stenosis; the cases with significant changes in brachial flow should be referred to angiography. In conclusion, clinical monitoring remains the backbone of any <jats:styled-content style=\"fixed-case\">VA<\/jats:styled-content> program. <jats:styled-content style=\"fixed-case\">CD<\/jats:styled-content>\u2010<jats:styled-content style=\"fixed-case\">US<\/jats:styled-content> is of utmost importance in a patient\u2010centered <jats:styled-content style=\"fixed-case\">VA<\/jats:styled-content> evaluation, because it allows the appropriate management of all aspects of <jats:styled-content style=\"fixed-case\">VA<\/jats:styled-content> care. These are the main reasons why we strongly advocate the adoption of a <jats:styled-content style=\"fixed-case\">VA<\/jats:styled-content> surveillance program based on <jats:styled-content style=\"fixed-case\">CD<\/jats:styled-content>\u2010<jats:styled-content style=\"fixed-case\">US<\/jats:styled-content>.<\/jats:p>","DOI":"10.1111\/sdi.12312","type":"journal-article","created":{"date-parts":[[2014,9,29]],"date-time":"2014-09-29T06:22:08Z","timestamp":1411971728000},"page":"211-215","source":"Crossref","is-referenced-by-count":41,"title":["The Key Role of Color Doppler Ultrasound in the Work\u2010up of Hemodialysis Vascular Access"],"prefix":"10.1111","volume":"28","author":[{"given":"Carlo","family":"Lomonte","sequence":"first","affiliation":[{"name":"Nephrology Unit Miulli General Hospital Acquaviva delle Fonti Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Meola","sequence":"additional","affiliation":[{"name":"S.
