Currently there is no standardized method for characterization of traumatic aneurysms. For the carotid and vertebral injury study (CAVIS), a prospective study of traumatic cerebrovascular injury, we established a method for aneurysm characterization and tested its reliability. Saccular aneurysm size was defined as the greatest linear distance between the expected location of the normal artery wall and the outer edge of the aneurysm lumen (\u201cdepth\u201d). Fusiform aneurysm size was defined as the \u201cdepth\u201d and longitudinal distance (\u201clength\u201d) paralleling the normal artery. The size of the aneurysm relative to the normal artery was also assessed. Reliability measurements were made using four raters who independently reviewed 15 computed tomographic angiograms (CTAs) and 13 digital subtraction angiograms (DSAs) demonstrating a traumatic aneurysm of the internal carotid artery. Raters categorized the aneurysms as either \u201csaccular\u201d or \u201cfusiform\u201d and made measurements. Five scans of each imaging modality were repeated to evaluate intra-rater reliability. Fleiss\u2019s free-marginal multi-rater kappa (\u03ba), Cohen\u2019s kappa (\u03ba), and interclass correlation coefficient (ICC) determined inter- and intra-rater reliability. Inter-rater agreement as to the aneurysm \u201cshape\u201d was almost perfect for CTA (\u03ba\u2009=\u20090.82) and DSA (\u03ba\u2009=\u20090.897). Agreements on aneurysm \u201cdepth,\u201d \u201clength,\u201d \u201caneurysm plus parent artery,\u201d and \u201cparent artery\u201d for CTA and DSA were excellent (ICC\u2009&gt;\u20090.75). Intra-rater agreement as to aneurysm \u201cshape\u201d was substantial to almost perfect (\u03ba\u2009&gt;\u20090.60). The CAVIS method of traumatic aneurysm characterization has remarkable inter- and intra-rater reliability and will facilitate further studies of the natural history and management of extracranial cerebrovascular traumatic aneurysms.<\/jats:p>","DOI":"10.1177\/1591019915582165","type":"journal-article","created":{"date-parts":[[2015,5,5]],"date-time":"2015-05-05T21:21:52Z","timestamp":1430860912000},"page":"255-262","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Carotid and vertebral injury study (CAVIS) technique for characterization of blunt traumatic aneurysms with reliability assessment"],"prefix":"10.1177","volume":"21","author":[{"given":"Christoph J","family":"Griessenauer","sequence":"first","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University of Alabama at Birmingham, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Foreman","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University of Alabama at Birmingham, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammadali M","family":"Shoja","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University of Alabama at Birmingham, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimberly P","family":"Kicielinski","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University of Alabama at Birmingham, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John P","family":"Deveikis","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University of Alabama at Birmingham, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beverly C","family":"Walters","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University of Alabama at Birmingham, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark R","family":"Harrigan","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University of Alabama at Birmingham, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,5,5]]},"reference":[{"key":"bibr1-1591019915582165","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-199911000-00004"},{"key":"bibr2-1591019915582165","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0b013e318142d146"},{"key":"bibr3-1591019915582165","doi-asserted-by":"publisher","DOI":"10.3171\/2012.11.JNS121038"},{"key":"bibr4-1591019915582165","doi-asserted-by":"publisher","DOI":"10.1227\/NEU.0b013e318209ce03"},{"key":"bibr5-1591019915582165","doi-asserted-by":"crossref","unstructured":"Harrigan MR, Weinberg JA, Peaks YS, et\u00a0al.
