Two authors reviewed the CT images to determine the presence or absence of 30 injury profile variables and quantified selected variables. The CT characteristics in patients with and without arterial injuries were compared using univariate analysis, multivariate analysis, and receiver operating characteristic (ROC) curve analysis to determine the respective risk factors, independent predictors, and optimal threshold values for the continuous variables.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Fifty-five patients were eligible for study inclusion. The risk factors for an intracranial arterial injury on univariate analysis were an entry wound over the frontobasal-temporal regions, a bihemispheric wound trajectory, a wound trajectory in proximity to the circle of Willis (COW), a subarachnoid hemorrhage (SAH), a higher SAH score, an intraventricular hemorrhage (IVH), and a higher IVH score. A trajectory in proximity to the COW was the best predictor of injury (OR 6.8 and p = 0.005 for all penetrating brain injuries [PBIs]; OR 13.3 and p = 0.001 for gunshot wounds [GSWs]). Significant quantitative variables were higher SAH and IVH scores. An SAH score of 3 (area under the ROC curve [AUC] for all PBIs 0.72; AUC for GSWs 0.71) and an IVH score of 3 (AUC for all PBIs 0.65; AUC for GSWs 0.65) could be used as threshold values to suggest an arterial injury.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>The risk factors identified may help radiologists suggest the possibility of arterial injury and prioritize neurointerventional consultation and potential DSA studies.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2014.9.jns14679","type":"journal-article","created":{"date-parts":[[2014,10,31]],"date-time":"2014-10-31T14:03:24Z","timestamp":1414764204000},"page":"219-226","source":"Crossref","is-referenced-by-count":41,"title":["Arterial injuries after penetrating brain injury in civilians: risk factors on admission head computed tomography"],"prefix":"10.3171","volume":"122","author":[{"given":"Uttam K.","family":"Bodanapally","sequence":"first","affiliation":[{"name":"Departments of Radiology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nitima","family":"Saksobhavivat","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathirkamanathan","family":"Shanmuganathan","sequence":"additional","affiliation":[{"name":"Departments of Radiology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bizhan","family":"Aarabi","sequence":"additional","affiliation":[{"name":"Neurosurgery, R Adams Cowley Shock Trauma Center, University of Maryland Medical Center, Baltimore, Maryland; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashis K.","family":"Roy","sequence":"additional","affiliation":[{"name":"Departments of Radiology and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns14679","series-title":"Neurosurg Clin N Am","doi-asserted-by":"publisher","first-page":"775","DOI":"10.1016\/S1042-3680(18)30432-7","article-title":"Management of traumatic aneurysms caused by high-velocity missile head wounds","volume":"6","author":"Aarabi","year":"1995"},{"key":"b2-jns14679","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1056","DOI":"10.1227\/00006123-198806010-00014","article-title":"Traumatic aneurysms of brain due to high velocity missile head wounds","volume":"22","author":"Aarabi","year":"1988"},{"issue":"2 Suppl","key":"b3-jns14679","series-title":"J Trauma","doi-asserted-by":"publisher","first-page":"S26","DOI":"10.1097\/00005373-200108001-00007","article-title":"Vascular complications of penetrating brain injury","volume":"51","author":"Aarabi","year":"2001"},{"key":"b4-jns14679","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"769","DOI":"10.3171\/jns.1996.84.5.0769","article-title":"Traumatic aneurysms and arteriovenous fistulas of intracranial vessels associated with penetrating head injuries occurring during war: principles and pitfalls in diagnosis and management.
