Treatment of stent occlusion requires the removal of a large amount of fresh or organized thrombus from stents with a diameter of 12\u201320 mm. The feasibility of large-bore rotational thrombectomy in combination with angioplasty to treat thrombosed venous iliofemoral or inferior vena cava stents has not been investigated yet. Patients and methods: Between May 2023 and June 2024, 12 patients (15 limbs) with symptomatic venous stent occlusions were treated at our institution with the 10-French Rotarex\u2122 thrombectomy device and completed 3-month follow-up by Duplex ultrasound. The primary outcome was primary patency at 90 days after thrombectomy of stent occlusion. Safety outcomes included device-related complications, bleeding, and death. Results: Median age was 41 years, 75% were women. At the index procedure, 10 (83%) patients presented with PTS and two (17%) with acute DVT. Median time from index procedure to re-intervention was 1125 (Q1\u2013Q3: 897\u20132297) days and from symptom onset to re-intervention 39 (Q1\u2013Q3: 8\u2013186) days. Technical success of re-intervention was achieved in all cases, and bail-out stent-in-stent placement was not required in 5 (33%) limbs. The primary patency rate at 90 days was 86.7% (95% CI: 71.0\u2013100.0). Two (17%) patients experienced recurrent stent thrombosis and were managed conservatively. Peri-interventional minor bleeding occurred in two (17%) patients. There were no device-related complications, major bleeding, or deaths. Conclusions: Large-bore rotational thrombectomy appears to be a feasible strategy to treat iliofemoral and inferior vena cava stent thrombosis, achieving acceptable short-term patency without major adverse events.<\/jats:p>","DOI":"10.1024\/0301-1526\/a001176","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T03:02:16Z","timestamp":1737342136000},"page":"400-405","source":"Crossref","is-referenced-by-count":2,"title":["Large-bore rotational thrombectomy and balloon angioplasty for thrombus fragmentation and removal from occluded iliofemoral or inferior vena cava stents"],"prefix":"10.1024","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0810-750X","authenticated-orcid":true,"given":"Gabor","family":"Forgo","sequence":"first","affiliation":[{"name":"Department of Angiology, University Hospital Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6794-1986","authenticated-orcid":true,"given":"Riccardo","family":"Fumagalli","sequence":"additional","affiliation":[{"name":"Department of Angiology, University Hospital Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9567-4865","authenticated-orcid":true,"given":"Silvia","family":"Cardi","sequence":"additional","affiliation":[{"name":"Department of Angiology, University Hospital Zurich, Switzerland"},{"name":"Department of Biomedical Sciences, Humanitas University, Pieve Emanuele, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2618-347X","authenticated-orcid":true,"given":"Stefano","family":"Barco","sequence":"additional","affiliation":[{"name":"Department of Angiology, University Hospital Zurich, Switzerland"},{"name":"Centre for Thrombosis and Hemostasis, University Medical Centre Mainz, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nils","family":"Kucher","sequence":"additional","affiliation":[{"name":"Department of Angiology, University Hospital Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0446-2862","authenticated-orcid":true,"given":"Tim","family":"Sebastian","sequence":"additional","affiliation":[{"name":"Department of Angiology, University Hospital Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"101","reference":[{"key":"c1","doi-asserted-by":"publisher","DOI":"10.1016\/S2352-3026(19)30209-1"},{"key":"c2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(11)61753-4"},{"key":"c3","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22638"},{"key":"c4","doi-asserted-by":"publisher","DOI":"10.23736\/S0392-9590.21.04659-9"},{"key":"c5","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2021.12.024"},{"key":"c6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvsv.2021.06.009"},{"key":"c7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvsv.2021.10.011"},{"key":"c8","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.115.002772"},{"key":"c9","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.120.009673"},{"key":"c10","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-021-02975-2"},{"key":"c11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2024.02.025"},{"key":"c12","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2024.01.030"},{"key":"c13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvsv.2018.07.013"},{"key":"c14","doi-asserted-by":"publisher","DOI":"10.1016\/j.carrev.2013.08.005"},{"key":"c15","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2009.04.034"},{"key":"c16","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2020.05.011"},{"key":"c17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1538-7836.2005.01204.x"},{"key":"c18","doi-asserted-by":"publisher","DOI":"10.1177\/1526602819857240"}],"container-title":["Vasa"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0301-1526\/a001176","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T07:05:42Z","timestamp":1762153542000},"score":1,"resource":{"primary":{"URL":"https:\/\/econtent.hogrefe.com\/doi\/10.1024\/0301-1526\/a001176"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11]]},"references-count":18,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2025,11]]}},"alternative-id":["10.1024\/0301-1526\/a001176"],"URL":"https:\/\/doi.org\/10.1024\/0301-1526\/a001176","relation":{},"ISSN":["0301-1526","1664-2872"],"issn-type":[{"type":"print","value":"0301-1526"},{"type":"electronic","value":"1664-2872"}],"subject":[],"published":{"date-parts":[[2025,11]]}}}
