A computed-tomography angiography (CTA) revealed extrinsic compression of the inferior vena cava from enlarged osteophytes. Venography and intravascular ultrasound were performed, confirming the diagnosis. A self-expanding venous stent was successfully deployed in the inferior vena cava relieving the extrinsic compression. The edema resolved the following day and was discharged without complications. The second patient is a 61-year-old male that presented to the emergency department with a left iliofemoral deep venous thrombosis. CTA showed left iliac vein compression by a lumbar osteophyte. Percutaneous thrombectomy was successfully achieved and an expanding stent was deployed covering the entire lesion. One month after the procedure the patient died from COVID-19\u2010associated respiratory failure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Osteophytes must be considered when dealing with extrinsic venous compression, especially in elderly people.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17085381221084815","type":"journal-article","created":{"date-parts":[[2022,4,7]],"date-time":"2022-04-07T22:10:19Z","timestamp":1649369419000},"page":"813-817","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Extrinsic venous compression secondary to spine osteophytes"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5101-1541","authenticated-orcid":false,"given":"Mauricio","family":"Gonzalez-Urquijo","sequence":"first","affiliation":[{"name":"Departamento de Cirug\u00eda Vascular y Endovascular, Escuela de Medicina, Pontificia Universidad Cat\u00f3lica de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose","family":"Torrealba","sequence":"additional","affiliation":[{"name":"Departamento de Cirug\u00eda Vascular y Endovascular, Escuela de Medicina, Pontificia Universidad Cat\u00f3lica de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Francisco","family":"Vargas","sequence":"additional","affiliation":[{"name":"Departamento de Cirug\u00eda Vascular y Endovascular, Escuela de Medicina, Pontificia Universidad Cat\u00f3lica de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renato","family":"Mertens","sequence":"additional","affiliation":[{"name":"Departamento de Cirug\u00eda Vascular y Endovascular, Escuela de Medicina, Pontificia Universidad Cat\u00f3lica de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leopoldo","family":"Marin\u00e9","sequence":"additional","affiliation":[{"name":"Departamento de Cirug\u00eda Vascular y Endovascular, Escuela de Medicina, Pontificia Universidad Cat\u00f3lica de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"Vald\u00e9s","sequence":"additional","affiliation":[{"name":"Departamento de Cirug\u00eda Vascular y Endovascular, Escuela de Medicina, Pontificia Universidad Cat\u00f3lica de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,4,7]]},"reference":[{"key":"bibr1-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1007\/s11936-017-0541-7"},{"key":"bibr2-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjmed.2010.01.027"},{"key":"bibr3-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvscit.2019.05.006"},{"key":"bibr4-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1177\/1538574417697208"},{"key":"bibr5-17085381221084815","doi-asserted-by":"publisher","DOI":"10.3171\/2014.6.SPINE13908"},{"key":"bibr6-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/4325830"},{"key":"bibr7-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1038\/scientificamerican08141880-102b"},{"key":"bibr8-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/723182"},{"key":"bibr9-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/709608"},{"key":"bibr10-17085381221084815","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.20130284"}],"container-title":["Vascular"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17085381221084815","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/17085381221084815","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17085381221084815","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:36:47Z","timestamp":1777707407000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/17085381221084815"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,4,7]]},"references-count":10,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2023,8]]}},"alternative-id":["10.1177\/17085381221084815"],"URL":"https:\/\/doi.org\/10.1177\/17085381221084815","relation":{},"ISSN":["1708-5381","1708-539X"],"issn-type":[{"value":"1708-5381","type":"print"},{"value":"1708-539X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,4,7]]}}}
