Methods: A single-center retrospective analysis was conducted involving 7 patients (mean age 61 years, range 49\u201372; 5 women) with 9 RAOs treated with endovascular revascularization between December 2014 and March 2017. Three patients had a solitary kidney with chronic renal insufficiency; 1 patient had bilateral occlusions as the acute event. Initial aortic surgery included 5 branched and 1 fenestrated EVAR as well as 1 open visceral debranching operation. Revascularization of the RAO was performed using aspiration thrombectomy, local lysis therapy, and stent-graft relining. The median time between initial aortic surgery and RAO was 10 months (range 0.5\u201317). Results: Median renal ischemic time to revascularization was 24 hours (range 7\u2013168). Technical success was 100%, with 1 procedure-related access complication. Temporary dialysis dependency occurred in 4 patients. Mean in-hospital stay was 17 days (range 7\u201332) with 1 postoperative death at day 10 due to cardiac arrest of unknown cause. Mean follow-up was 10.3 months (range 1.5\u201327) in 5 of 6 discharged patients. During follow-up, 1 reintervention for recurrent occlusion was performed. At follow-up imaging, all renal arteries were patent. No permanent dialysis dependency occurred. Conclusion: Renal function can be salvaged by delayed revascularization for RAO with prolonged renal ischemia. The endovascular approach with aspiration thrombectomy, local lysis, and stent-graft relining is a feasible technique for revascularization after RAO in patients with fenestrated-branched EVAR or open visceral debranching.<\/jats:p>","DOI":"10.1177\/1526602818783506","type":"journal-article","created":{"date-parts":[[2018,6,29]],"date-time":"2018-06-29T06:19:27Z","timestamp":1530253167000},"page":"466-473","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Renal Function Salvage After Delayed Endovascular Revascularization of Acute Renal Artery Occlusion in Patients With Fenestrated-Branched Endovascular Aneurysm Repair or Visceral Debranching"],"prefix":"10.1177","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8291-4831","authenticated-orcid":false,"given":"Franziska","family":"Heidemann","sequence":"first","affiliation":[{"name":"German Aortic Center Hamburg, Department of Vascular Medicine, University Heart Center, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9962-0204","authenticated-orcid":false,"given":"Tilo","family":"K\u00f6lbel","sequence":"additional","affiliation":[{"name":"German Aortic Center Hamburg, Department of Vascular Medicine, University Heart Center, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
