The centerline of each Three-dimensional aortic model was calculated using a repulsive force field method. Measurements of the aorta and supra-aortic branches were analyzed using Patran (finite-element software). A three-dimensional statistical aortic arch model was built using principal component analysis.<\/jats:p>\n                  <jats:p>Results: The mean diameters of the ascending and descending aorta, and the origins of the innominate, left common carotid, and left subclavian artery were 39.4\u2009\u00b1\u20096.7, 34.5\u2009\u00b1\u20097.9, 18.0\u2009\u00b1\u20093.8, 12.6\u2009\u00b1\u20092.7, and 14.1\u2009\u00b1\u20092.5\u2009mm, respectively. The length of the ascending aorta, innominate to left common carotid artery, and left common carotid to left subclavian artery were 62.6\u2009\u00b1\u200911.4, 12.0\u2009\u00b1\u20095.6, and 18.7\u2009\u00b1\u20095.6\u2009mm along the centerline. The mean angle of curvature was 103.8\u2009\u00b1\u200925 degrees. Principal component analysis of the three-dimensional centerlines derived 3 main modes of variation, which account for 61% of the overall shape range.<\/jats:p>\n                  <jats:p>Conclusion: Aortic arch anatomical information from an elderly Asian population can be useful for the development of future endovascular devices.<\/jats:p>","DOI":"10.1177\/0218492312449637","type":"journal-article","created":{"date-parts":[[2013,5,6]],"date-time":"2013-05-06T09:37:22Z","timestamp":1367833042000},"page":"151-159","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Anatomical characteristics of the thoracic aortic arch in an Asian population"],"prefix":"10.1177","volume":"21","author":[{"given":"Peixuan","family":"Chiu","sequence":"first","affiliation":[{"name":"Department of Surgery, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heow Pueh","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sudhakar K","family":"Venkatesh","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pei","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Surgery, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2013,4,1]]},"reference":[{"key":"bibr1-0218492312449637","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2007.06.005"},{"key":"bibr2-0218492312449637","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(00)00570-2"},{"key":"bibr3-0218492312449637","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2006.11.009"},{"key":"bibr4-0218492312449637","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.108.835926"},{"key":"bibr5-0218492312449637","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2006.11.019"},{"key":"bibr6-0218492312449637","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2009.09.043"},{"key":"bibr7-0218492312449637","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2010.07.001"},{"key":"bibr8-0218492312449637","doi-asserted-by":"crossref","unstructured":"Cornea ND, Silver D, Yuan X, Balasubramanian R.
