It may be a result of\u00a0in situ\u00a0thrombosis instead of dislodged deep vein thrombosis. Case description:\u00a0We present a 24-year-old patient involved in a motorcycle and car collision with blunt chest trauma, mild desaturation and a right clavicle fracture. A thorax computed tomography scan seven hours post-trauma revealed bilateral main pulmonary arteries thrombosis extending to the proximal segmental branches with no evidence of deep vein thrombosis or major thoracic injury. The patient was treated with low molecular weight heparin and discharged home after five days with a one-year follow-up. Discussion:\u00a0This could be related to an inflammatory cascade secondary to the trauma which led to endothelial damage and formation of a de novo thrombus in the pulmonary vessels. Conclusion: This case highlights the occurrence of immediate pulmonary embolism after minor blunt chest trauma in the absence of classical risk factors and has been treated successfully by low molecular weight heparin.<\/jats:p>","DOI":"10.12890\/2026_006150","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T13:54:52Z","timestamp":1769435692000},"source":"Crossref","is-referenced-by-count":1,"title":["Immediate pulmonary embolism or pulmonary artery thrombosis following blunt chest injury?"],"prefix":"10.12890","volume":"13","author":[{"given":"Tariq","family":"Siddiqui","sequence":"first","affiliation":[{"name":"Department of Surgery Trauma Surgery, Hamad General Hospital, Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khair","family":"Muhammad","sequence":"first","affiliation":[{"name":"Department of Radiology, Hamad General Hospital, Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2584-953X","authenticated-orcid":false,"given":"Ayman","family":"El-Menyar","sequence":"first","affiliation":[{"name":"Department of Surgery Trauma Surgery Clinical Research, Hamad General Hospital, Doha, Qatar; Department of Clinical Medicine, Weill Cornell Medicine, Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sajid","family":"Atique","sequence":"first","affiliation":[{"name":"Department of Surgery Trauma Surgery, Hamad General Hospital, Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalid","family":"Ahmed","sequence":"first","affiliation":[{"name":"Department of Surgery Trauma Surgery, Hamad General Hospital, Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandro","family":"Rizoli","sequence":"first","affiliation":[{"name":"Department of Surgery Trauma Surgery, Hamad General Hospital, Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hassan","family":"Al-Thani","sequence":"first","affiliation":[{"name":"Department of Surgery Trauma Surgery, Hamad General Hospital, Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10397","published-online":{"date-parts":[[2026,1,26]]},"reference":[{"key":"10.12890\/2026_006150_ref1","doi-asserted-by":"crossref","unstructured":"Leibowitz D.
