Objective To provide vessel anatomical materials guidance for endovascular aortic repair,the branches artery of thoracic aortic was studied by CT angiography (CTA).Methods From January 2008 to February 2012,739 adult cases' CTA data were collected,all cases performing thoracic CTA in Wuhan General Hospital of Guangzhou Command.We measured the diameter and/or leugth of the ascending aorta,aortic arch and branches artery of aortic arch,and made an analysis.Results The aortic arch includes standard and variant types.Standard type is common,which accounted for 91.1％ of the total number,while variant type accounted for 8.9％.In the standard aortic arch of patients,the diameter of aortic arch above the opening of coronary artery (CA) was (35.7 ±4.3) mm,the diameter of ascending aortic arch at the opening of brachiocephalic trunk (BCT) was (33.6 ±4.2) mm,the diameter of aortic arch between the BCT and the left common carotid artery (LCCA) was (29.4 ± 5.7) mm,the diameter of aortic arch between the LCCA and the left subclavian artery (LSA) was (27.6 ± 4.2) mm,the diameter of descending aortic at the opening of the LSA was (25.4 ± 4.5) mm,the diameter of the head BCT from aortic arch was (12.9 ±0.9) mm,the diameter of the head LCCA from aortic arch was (8.5 ± 0.7) mm,the diameter of the head LSA from aortic arch was (10.4 ± 1.1) mm,the length of aorta between the CA and the BCT was (53.3 ±12.5) mm,the length of aortic between the BCT and the LCCA was (4.7 ± 1.5) mm,the length of aortic between the LCCA and the LSA was (7.9 ± 2.6) mm,the length between the opening of BCT and the right subclavian artery (RSA) was (41.1 ± 8.2) mm,the length between the opening of LSA and the opening of left vertebral artery was (38.5 ±5.7) mm,the angle between the horizontal of BCT and the LCCA and the sagittal plane was (71.2 ± 7.2) °,the angle between the plane of LCCA and the LSA and the plane of sagittal was (31.1 ± 2.9)°.Conclusions The CT data of the thoracic aorta can be used as reference for production of stents and guide releasing the stents in endovascular repair.
