Our purpose was to assess the prevalence of early splenic CVI seen on admission CT in patients with splenic trauma admitted to a single level 1 trauma center in 2013\u20132021, and its detection in different CT protocols. A retrospective, single-center longitudinal cohort study. Nine-year data (2013\u20132021) of all patients with suspected or manifest abdominal trauma were retrieved. All patients,\u2009&gt;\u200915\u00a0years with an ICD code for splenic trauma (S36.0XX) were included. CT and angiographic examinations were identified. Reports and images were reviewed. Splenic CVI CT criterion was a focal collection of vascular contrast that decreases in attenuation with delayed imaging. Number of CVIs and treatment was based on medical records and\/or available angioembolization data. Of 2805 patients with abdominal trauma, 313 patients (313\/2805; 11.2%) fulfilled the study entry criteria. 256 patients (256\/313; 81.8%) had a CT examination. Sixteen patients had splenectomy before CT, and the final study group included 240 patients (240\/313; 76.7%). Median New Injury Severity Score (NISS) was 27 and 87.5% of patients had NISS\u2009&gt;\u200915. Splenic CVI was found in 20 patients, which yields a prevalence of 8.3% (20\/240; 95% CI 5.2\u201312.6%). In those cases with both late arterial and venous phase images available, CVI was seen in 14.5% of cases (18\/124, 95% CI 8.6\u201322.0%). None of the patients with CVI died within 30\u00a0days of the injury. The prevalence of early splenic CVI in patients with a splenic trauma was 8.3\u201314.5% (95% CI 5.2\u201322.0%). Our data suggests that both arterial and venous phase are needed for CT diagnosis. The 30-day outcome in terms of mortality was good.<\/jats:p>","DOI":"10.1038\/s41598-024-58626-2","type":"journal-article","created":{"date-parts":[[2024,4,4]],"date-time":"2024-04-04T06:01:52Z","timestamp":1712210512000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["The prevalence of early contained vascular injury of spleen"],"prefix":"10.1038","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9406-7676","authenticated-orcid":false,"given":"Seppo K.","family":"Koskinen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Z.","family":"Alagic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Enocson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Kistner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,4,4]]},"reference":[{"key":"58626_CR1","doi-asserted-by":"publisher","first-page":"413","DOI":"10.1016\/j.amjsurg.2005.10.046","volume":"191","author":"S Bjerke","year":"2006","unstructured":"Bjerke, S., Pohlman, T., Saywell, R.
