We aimed to evaluate the association between body mass index (BMI) and VA patency.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n We retrospectively analyzed 396 patients who underwent arteriovenous fistula (AVF) or arteriovenous graft (AVG) creation (2021\u20132024), stratifying them by BMI (cutoff of 30 kg\/m\u00b2). Primary outcomes included primary patency and assisted primary patency, secondary patency, and patient survival.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n We analyzed 396 patients (mean age 66.0 \u00b1 14.2 years; 62.1% male). Comorbidities were frequent: hypertension 94.2%, diabetes 54.8%, coronary artery disease 35.6%, peripheral arterial disease 21.7%, cerebrovascular disease 23.0%, and cancer 25.0%. Prior kidney transplantation and renal replacement therapy were present in 12.6% and 69.9% of patients, respectively. Left-sided access and autologous access was predominated (89.9% and 68.2% each), while secondary vascular access at presentation was uncommon (6.6%). The average follow up period was 8.36 \u00b1 9.27 months. Patients with obesity (BMI \u2a7e30) had significantly lower primary patency than those without obesity (25.0% vs 48.0%,\n p<\/jats:italic>\n = 0.024), with comparable assisted patency and long-term outcomes. BMI \u2a7e30 was an independent predictor of primary patency loss (hazard ratio (HR) 1.707,\n p<\/jats:italic>\n = 0.038). AVG formation was a risk factor for assisted patency failure (HR 8.983,\n p<\/jats:italic>\n < 0.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Obesity was associated with early access failure; not with long-term outcomes. Durable VA outcomes can be achieved in patients with obesity through surveillance and timely interventions.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/11297298251397289","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T06:09:52Z","timestamp":1765174192000},"page":"1294-1302","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Obesity is an independent risk factor for primary patency loss in 12 months: A 3-year retrospective study of vascular access outcomes"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1391-048X","authenticated-orcid":false,"given":"Young Jin","family":"Yoo","sequence":"first","affiliation":[{"name":"Department of Surgery, Yonsei University College of Medicine, Seoul, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0250-2229","authenticated-orcid":false,"given":"Seon-Hee","family":"Heo","sequence":"additional","affiliation":[{"name":"Department of Surgery, Yonsei University College of Medicine, Seoul, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,12,7]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41581-020-0333-2"},{"key":"e_1_3_3_3_2","article-title":"The society for vascular surgery: clinical practice guidelines for the surgical placement and maintenance of arteriovenous hemodialysis access","volume":"48","author":"Sidawy AN","year":"2008","unstructured":"Sidawy AN, Spergel LM, Besarab A, et al.
