Beyond detailed patient history and physical examination, duplex ultrasound (DU) evaluation is essential in preoperative vascular mapping. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> A retrospective descriptive nonrandomized study was performed and included 108 end-stage kidney disease patients referred from eight HD centers to be assessed for creation of an arteriovenous (AV) access (AV fistula or AV graft). We assessed primary failure, primary unassisted patency (PP) and primary assisted patency (PAP) rates and cumulative survival of AV accesses at 6 and 12 months. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> We created 86 AV accesses of which 79 (91.9%) were AV fistulas (AVFs) (29 distal AVFs, 49 proximal AVFs and 1 femorofemoral AVF) and 7 (8.1%) arteriovenous grafts (AVGs). Fifteen percent (15%) (n = 12) of primary failure occurred in the AVF group. Any case of primary failure was observed between AVGs. In the AVF group, PP at 6 months was 63.8% and at 12 months was 48.3%, PAP was 80.7% at 6 and 12 months. PP excluding primary failures was 73.0% and 55.3% at 6 and 12 months, respectively. The cumulative survival at 6 and 12 months was 80.7%. In the AVG group, PP at 6 months and 12 months was 66.7%, PAP and cumulative survival at 6 and 12 months were of 100%. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> This study demonstrates that preoperative vascular mapping with a patient-centered approach may be critical to achieve good outcomes allowing the increase in AVF access. <\/jats:p><\/jats:sec>","DOI":"10.5301\/jva.5000559","type":"journal-article","created":{"date-parts":[[2016,6,22]],"date-time":"2016-06-22T10:22:16Z","timestamp":1466590936000},"page":"320-327","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Preoperative Vessel Mapping in Chronic Kidney Disease Patients - a Center Experience"],"prefix":"10.1177","volume":"17","author":[{"given":"Patr\u00edcia","family":"Barreto","sequence":"first","affiliation":[{"name":"Nephrology Department, Centro Hospitalar de Vila Nova de Gaia, Vila Nova de Gaia - Portugal"},{"name":"Nephrology Department, Centro Hospitalar do Porto, Porto - Portugal"}]},{"given":"Paulo","family":"Almeida","sequence":"additional","affiliation":[{"name":"Vascular Surgery Department, Centro Hospitalar do Porto, Porto - Portugal"},{"name":"Vascular Access Centre, NephroCare Portugal, Porto - Portugal"},{"name":"Grupo de Estudos Vasculares (GEV), Porto - Portugal"}]},{"given":"Norton","family":"de Matos","sequence":"additional","affiliation":[{"name":"Vascular Surgery Department, Centro Hospitalar do Porto, Porto - Portugal"},{"name":"Vascular Access Centre, NephroCare Portugal, Porto - Portugal"},{"name":"Grupo de Estudos Vasculares (GEV), Porto - Portugal"}]},{"given":"Jos\u00e9 Alexandre","family":"Queir\u00f3s","sequence":"additional","affiliation":[{"name":"Nephrology Department, Centro Hospitalar do Porto, Porto - Portugal"},{"name":"Vascular Access Centre, NephroCare Portugal, Porto - Portugal"}]},{"given":"Joaquim","family":"Pinheiro","sequence":"additional","affiliation":[{"name":"Vascular Access Centre, NephroCare Portugal, Porto - Portugal"}]},{"given":"Fernanda","family":"Silva","sequence":"additional","affiliation":[{"name":"Nephrology Department, Centro Hospitalar do Porto, Porto - Portugal"}]},{"given":"Telmo","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Vascular Access Centre, NephroCare Portugal, Porto - Portugal"}]},{"given":"Rui","family":"Almeida","sequence":"additional","affiliation":[{"name":"Vascular Surgery Department, Centro Hospitalar do Porto, Porto - Portugal"}]},{"given":"Ant\u00f3nio","family":"Cabrita","sequence":"additional","affiliation":[{"name":"Nephrology Department, Centro Hospitalar do Porto, Porto - Portugal"}]}],"member":"179","published-online":{"date-parts":[[2016,5,31]]},"reference":[{"key":"bibr1-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1177\/112972980800900101"},{"key":"bibr2-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfn001"},{"key":"bibr3-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2013.08.023"},{"key":"bibr4-jva.5000559","doi-asserted-by":"publisher","DOI":"10.5301\/jva.5000163"},{"key":"bibr5-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(98)70360-X"},{"key":"bibr6-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1755.2001.00031.x"},{"key":"bibr7-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfh244"},{"key":"bibr8-jva.5000559","doi-asserted-by":"publisher","DOI":"10.2215\/CJN.03480807"},{"key":"bibr9-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-139X.2003.16069.x"},{"key":"bibr10-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfi340"},{"key":"bibr11-jva.5000559","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2006.25.12.1541"},{"key":"bibr12-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-139X.2003.16069.x"},{"key":"bibr13-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1053\/ajkd.2002.33394"},{"key":"bibr14-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2006.01.033"},{"key":"bibr15-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2011.05.014"},{"key":"bibr16-jva.5000559","doi-asserted-by":"publisher","DOI":"10.5301\/jva.5000163"},{"key":"bibr17-jva.5000559","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.211.2.r99ma08579"},{"key":"bibr18-jva.5000559","unstructured":"NKF-K\/DOQI.
