Therefore, this study aimed to analyze the anatomy of the IJV across various patients and to relate the differences in anatomy to basic patient characteristics. Materials and Methods: This retrospective study included a total of 313 patients who underwent contrast-enhanced neck computed tomography between January 2017 and December 2018. The circumferences of the right and left IJVs were measured at three locations (hyoid bone, cricoid cartilage, and first thoracic vertebra) and parameters affecting the size of the IJV were analyzed. Results: The right IJV was significantly larger than the left IJV at each position (p &lt; 0.001), and the area of the lumen was the largest at the cricoid cartilage level (p &lt; 0.001). After dividing the right IJV data into two groups (above and below the median area), multivariate logistic regression analysis showed that age (odds ratio (OR) 1.040; 95% confidence interval (CI) 1.022\u20131.058, p &lt; 0.001) and body mass index (BMI, OR 1.080; 95% CI 1.011\u20131.154, p = 0.0.23) affected size. Conclusions: The right IJV is larger than the left and has a rhomboid morphology. Age and BMI are significant factors affecting the IJV size.<\/jats:p>","DOI":"10.3390\/medicina56030135","type":"journal-article","created":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T03:54:14Z","timestamp":1584590054000},"page":"135","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Anatomical Morphology Analysis of Internal Jugular Veins and Factors Affecting Internal Jugular Vein Size"],"prefix":"10.3390","volume":"56","author":[{"given":"Jae Cheon","family":"Jeon","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Dongsan Medical Center, Keimyung University School of Medicine, Daegu 42601, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Woo Ik","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Dongsan Medical Center, Keimyung University School of Medicine, Daegu 42601, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5562-0720","authenticated-orcid":false,"given":"Jae Ho","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Keimyung University School of Medicine, Daegu 42601, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4303-7375","authenticated-orcid":false,"given":"Sang Hun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Dongsan Medical Center, Keimyung University School of Medicine, Daegu 42601, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"138","DOI":"10.1016\/j.aenj.2015.12.003","article-title":"Peripheral intravenous catheter insertion in the Emergency Department","volume":"19","author":"Decker","year":"2016","journal-title":"Australas Emerg.
