Therefore, the objective of this study was to evaluate the safety and efficacy of pre-operative venograms in pre-end-stage kidney disease (ESKD) patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We performed a retrospective cohort study (2018\u20132022) of consecutive pre-ESKD patients who underwent staged bilateral venograms for preoperative vein mapping prior to hemodialysis access creation at a tertiary care medical center. Patients were identified through an institutional database and data were extracted with chart review adjudication. The primary safety outcome was a composite of unplanned dialysis initiation within 7\u2009days of venogram or development of contrast-induced AKI. Secondary outcomes included vascular access creation within 1\u2009year of index venogram.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 142 pre-ESKD patients underwent 284 venograms. Mean (SD) age was 67 (14) years; 55% were female; and 65% of patients had stage 5 CKD, whereas 35% had stage 3 or 4 CKD. Rate of the primary safety outcome was 2.5%, which was driven by a 2.5% rate of contrast-induced AKI with no instances of unplanned dialysis initiation within 7\u2009days of either venogram. Ultimately, 120 (85%) vascular accesses were created, of which 96% were autogenous fistulas. Forearm arteriovenous fistulas (AVFs) were the most common configuration (69%) followed by upper arm AVFs (27%); AV grafts were created in 4% of cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In a population of pre-ESKD patients, staged bilateral venograms led to few cases of reversible contrast-induced AKI with no instances of unplanned dialysis initiation. Furthermore, access creation was achieved in 85% of patients with the majority consisting of forearm AVFs. Therefore, preoperative venography for access planning appears safe in pre-ESKD patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11297298241311397","type":"journal-article","created":{"date-parts":[[2025,1,16]],"date-time":"2025-01-16T06:10:25Z","timestamp":1737007825000},"page":"1908-1913","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Safety of pre-operative venogram for hemodialysis access planning in pre-end-stage kidney disease patients"],"prefix":"10.1177","volume":"26","author":[{"given":"Lucinda R","family":"Holden-Wingate","sequence":"first","affiliation":[{"name":"University of California, Los Angeles, Los Angeles, CA, USA"},{"name":"Division of Vascular and Endovascular Surgery, Brigham and Women\u2019s Hospital, Boston, MA, USA"},{"name":"Center for Surgery and Public Health, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James J","family":"Fitzgibbon","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Brigham and Women\u2019s Hospital, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abena","family":"Appah-Sampong","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Brigham and Women\u2019s Hospital, Boston, MA, USA"},{"name":"Center for Surgery and Public Health, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar","family":"Rana","sequence":"additional","affiliation":[{"name":"Boston University School of Medicine, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-8709-4399","authenticated-orcid":false,"given":"Christopher","family":"Holden-Wingate","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Brigham and Women\u2019s Hospital, Boston, MA, USA"},{"name":"University of Illinois College of Medicine, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Cruz","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Brigham and Women\u2019s Hospital, Boston, MA, USA"},{"name":"Center for Surgery and Public Health, Boston, MA, USA"},{"name":"University of Texas Rio Grande Valley School of Medicine, Edinburg, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengyuan","family":"Ruan","sequence":"additional","affiliation":[{"name":"Center for Surgery and Public Health, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles Keith","family":"Ozaki","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Brigham and Women\u2019s Hospital, Boston, MA, USA"},{"name":"Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4161-7122","authenticated-orcid":false,"given":"Dirk M","family":"Hentschel","sequence":"additional","affiliation":[{"name":"Harvard Medical School, Boston, MA, USA"},{"name":"Division of Renal Medicine, Brigham and Women\u2019s Hospital, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2471-8167","authenticated-orcid":false,"given":"Mohamad A","family":"Hussain","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Brigham and Women\u2019s Hospital, Boston, MA, USA"},{"name":"Center for Surgery and Public Health, Boston, MA, USA"},{"name":"Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,1,16]]},"reference":[{"key":"e_1_3_2_2_2","unstructured":"USRDS.
