Patency from stent graft placement to 1st target lesion revascularization (TLR), from 1st to 2nd TLR, and from 2nd to 3rd TLR was defined as 1st, 2nd, and 3rd TLPP, respectively. We divided target lesion restenosis into two groups: pattern E (edge), which extended up to 5\u2009mm from the downstream edge of stent graft, and pattern D (downstream), which extended beyond 5\u2009mm distal to the downstream edge of stent graft. TLPP was estimated using Kaplan\u2013Meier analysis, and multivariable Cox proportional hazards regression was performed to identify predictors TLPP. The correlation between the elephant trunk (ET) technique (stent graft diameter\u2009<\u2009outflow vein diameter) and the restenosis pattern was evaluated using Fisher\u2019s exact test.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The 1st TLPP, 2nd TLPP, and 3rd TLPP were 81%, 41%, and 17% at 6\u2009months, respectively. There was no significant difference in the TLPP between the groups with and without ET technique. The second TLPP in the Pattern D group was significantly worse than in the Pattern E group (\n p<\/jats:italic>\n \u2009<\u20090.005). On multivariable analysis, restenosis pattern (HR\u2009=\u20093.23 (1.59\u20136.53),\n p<\/jats:italic>\n \u2009=\u20090.001) and female sex (HR\u2009=\u20092.33 (1.17\u20134.68),\n p<\/jats:italic>\n \u2009=\u20090.017) were significant predictors of 2nd TLPP. Fisher\u2019s exact test revealed a significant positive correlation between the ET technique and pattern E restenosis (\n p<\/jats:italic>\n \u2009=\u20090.014, <0.001, and <0.001, for 1st, 2nd, and 3rd target lesion, respectively).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Time to loss of TLPP was progressively reduced with each successive balloon angioplasty. Pattern D was associated with poorer TLPP. Restenosis pattern E was significantly correlated with ET technique.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/11297298261417906","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T04:27:48Z","timestamp":1773635268000},"page":"1800-1809","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Restenosis patterns and clinical significance following VIABAHN endoprosthesis placement for refractory arteriovenous graft outflow stenosis"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5753-0665","authenticated-orcid":false,"given":"Daihiko","family":"Eguchi","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, Fukuoka City Hospital, Fukuoka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenichi","family":"Honma","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Fukuoka City Hospital, Fukuoka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,3,15]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2018.12.006"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298241286249"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-139X.2003.16066.x"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.RVI.0000094618.61428.58"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/bmt.2012.244"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2016.04.035"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2017.12.062"},{"key":"e_1_3_2_9_2","first-page":"4","article-title":"Undersizing to the outflow vein","volume":"17","author":"Patel DV.","year":"2018","unstructured":"Patel DV.
