The primary outcome measure was the loss of primary patency after DCB. The secondary outcome measures were the factors associated with early (<90\u2009days) and late (\u2a7e90\u2009days) losses of primary patency after DCB.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The primary patency rates 6 and 12\u2009months after DCB were 72.5%\u2009\u00b1\u20092.3% and 40.1%\u2009\u00b1\u20092.7%, respectively. The factors associated with the early loss of primary patency were de novo lesions (adjusted hazard ratio [HR], 7.91; [95% confidence interval (CI), 1.90\u201332.97];\n p<\/jats:italic>\n \u2009=\u20090.005), endovascular treatment (EVT) history within the previous 90\u2009days (adjusted HR, 9.29; [95% CI, 3.09\u201327.92];\n p<\/jats:italic>\n \u2009<\u20090.001) and juxta-anastomotic stenosis (adjusted HR, 0.30; [95% CI, 0.13\u20130.70];\n p<\/jats:italic>\n \u2009=\u20090.005). The factors associated with a late loss of primary patency included EVT history within the previous 90\u2009days (adjusted HR, 2.52; [95% CI, 1.89\u20133.38];\n p<\/jats:italic>\n \u2009<\u20090.001) and pre-dilation balloon size (adjusted HR, 1.99; [95% CI, 1.50\u20132.64];\n p<\/jats:italic>\n \u2009<\u20090.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n DCB is an effective device to prolong the patency of dysfunctional AVFs in most cases. De novo lesions and their locations were associated with an early loss of primary patency, whereas the vessel preparation balloon size was associated with a late loss of primary patency. EVT history within the previous 90\u2009days was associated with early and late losses of primary patency.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/11297298251314065","type":"journal-article","created":{"date-parts":[[2025,1,29]],"date-time":"2025-01-29T11:33:38Z","timestamp":1738150418000},"page":"1970-1978","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Factors associated with early and late losses of primary patency following drug-coated balloon for dysfunctional arteriovenous fistula"],"prefix":"10.1177","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4251-5315","authenticated-orcid":false,"given":"Kotaro","family":"Suemitsu","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Division of Kidney and Dialysis, Kansai Rosai Hospital, Amagasaki, Japan"},{"name":"Department of Nephrology, Osaka Police Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osamu","family":"Iida","sequence":"additional","affiliation":[{"name":"Cardiovascular Division, Osaka Police Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Sato","sequence":"additional","affiliation":[{"name":"Yokohama Daiichi Hospital Vascular Access Center, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahito","family":"Miyamoto","sequence":"additional","affiliation":[{"name":"Yokohama Daiichi Hospital Vascular Access Center, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2294-194X","authenticated-orcid":false,"given":"Masaaki","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Shizuoka General Hospital, Shizuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taku","family":"Toyoshima","sequence":"additional","affiliation":[{"name":"Cardiovascular Division, Osaka Police Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaaki","family":"Izumi","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Division of Kidney and Dialysis, Kansai Rosai Hospital, Amagasaki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,1,29]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2013.08.023"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamasurg.2021.4527"},{"key":"e_1_3_3_4_2","article-title":"KDOQI clinical practice guidelines and clinical practice recommendations for 2006 updates: hemodialysis adequacy, peritoneal dialysis adequacy, and vascular access","volume":"48","author":"National Kidney Foundation","year":"2006","unstructured":"National Kidney Foundation.
