However, injury to the thoracic aorta during pedicle screw insertion is rare, delayed presentation secondary to pseudoaneurysm is even rarer, the pseudoaneurysm formation caused by a series of malpositioned pedicle screws has perhaps not been reported so far.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case presentation<\/jats:title><jats:p>In this paper, we report here a case in which inadvertent injury to the thoracic aorta resulted in pseudoaneurysm, its manifestation was initially vague, resulting in a delayed diagnosis. Delayed aortic pseudoaneurysm or injury can be asymptomatic for a long time. Patients with renewed or continued back pain should alert orthopaedic surgeons regarding the possibility of pseudoaneurysms, regardless of the period that has elapsed after pedicle screw implantation.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.12793","type":"journal-article","created":{"date-parts":[[2021,1,10]],"date-time":"2021-01-10T10:50:39Z","timestamp":1610275839000},"page":"338-341","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Delayed Presentation of Thoracic Aortic Pseudoaneurysm Following Pedicle Screw Implantation: A Case Report"],"prefix":"10.1111","volume":"13","author":[{"given":"Li\u2010di","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Spine Surgery The First Hospital of Jilin University  Changchun China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery Japan Union Hospital of Jilin University  Changchun China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiang\u2010bi","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery The First Hospital of Jilin University  Changchun China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6119-9998","authenticated-orcid":false,"given":"Shao\u2010kun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery The First Hospital of Jilin University  Changchun China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,1,6]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-200101000-00029"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2007.11.005"},{"key":"e_1_2_5_4_1","first-page":"631","article-title":"Spontaneous abdominal aortic rupture from erosion by a lumbar spine fixation device: a case report","volume":"99","author":"Jendrisak MD","year":"1986","journal-title":"Surgery"},{"key":"e_1_2_5_5_1","first-page":"253","article-title":"Delayed aortic rupture caused by an implanted anterior spinal device.
