Fresh frozen plasma (FFP) administration is often necessary to treat coagulation disorders associated with TBI. This study aimed to determine the relationship between the presence of extravascular leakage on contrast-enhanced head CT, fibrinogen level at admission, and FFP administration in patients with TBI. The medical records of patients with TBI \u226518 years of age referred to our hospital between January 2010 and December 2020 were examined retrospectively. Patients who underwent contrast-enhanced CT immediately after admission were selected, and the presence or absence of extravascular leakage, fibrinogen level at admission, and percentage of patients who required FFP administration within 24\u2009h of admission were examined; 172 patients were included. Multi-variable linear regression analysis was performed to determine the effects of contrast extravasation on fibrinogen levels at admission and was adjusted for age, sex, systolic blood pressure, time from injury to admission, Marshall CT score, Glasgow Coma Scale score at admission, Injury Severity Score, and need for emergency surgery; the regression coefficient was \u221219.8. The effect of extravasation on FFP administration within 24\u2009h of admission was analyzed using logistic regression while adjusting for age, systolic blood pressure, Marshall CT score, need for emergency surgery, and fibrinogen level at admission. The odds ratio of contrast extravasation was 7.08 after adjustment. Extravascular leakage is associated with fibrinogen levels at admission and FFP administration within 24\u2009h of admission.<\/jats:p>","DOI":"10.1089\/neur.2022.0054","type":"journal-article","created":{"date-parts":[[2023,1,3]],"date-time":"2023-01-03T10:19:24Z","timestamp":1672741164000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Association of Extravascular Leakage on Computed Tomography Angiography with Fibrinogen Levels at Admission in Patients with Traumatic Brain Injury"],"prefix":"10.1177","volume":"4","author":[{"given":"Hiroshi","family":"Ito","sequence":"first","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youhei","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Togami","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinya","family":"Onishi","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunichiro","family":"Nakao","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiro","family":"Iba","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Ogura","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Oda","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine, Osaka University Graduate School of Medicine, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,12,26]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12028-020-01151-7"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.TA.0000159249.68363.78"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00701-019-04111-z"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1152\/ajpendo.00137.2005"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0b013e3180cc2e94"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13017-020-00332-1"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-019-2347-3"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00701-019-04010-3"},{"key":"e_1_3_7_10_2","volume":"29","author":"Aubron C","year":"2014","unstructured":"Aubron C, , Reade MC, , Fraser JF, et al.
