摘要
目的利用CT血管造影测量胸主动脉分支血管，为胸主动脉腔内修复技术提供相关的血管解剖指导。方法收集2008年1月－2012年2月在广州军区武汉总医院进行胸主动脉CT血管造影检查的739例患者资料，测量升主动脉、主动脉弓、弓上分支的直径和长度，并进行统计、分析。结果主动脉弓分为标准型和变异型，其中标准型最常见，占总例数的91．1％，变异型占8．9％。主动脉弓标准型患者的冠状动脉开口处升主动脉直径为（35．7±4．3）mm，头臂干开口处升主动脉直径为（33．6±4．2）mm，头臂十与左颈总动脉之间的主动脉弓直径为（29．4±5．7）mm，左颈总动脉与左锁饲’下动脉之间的主动脉弓直径为（27．6±4．2）mm，左锁骨下动脉开口处降主动脉直径为（25．4±4．5）mm，头臂干存主动脉弓分支处的直径为（12．9±0．9）mm，左颈总动脉在主动脉弓分支处的直径为（8．5±0．7）mm，左锁骨下动脉在主动脉弓分支处的直径为（10．4±1．1）mm，冠状动脉与又臂十之间的管壁长度为（53．3±12．5）mm，头臂千与左颈总动脉之间的管壁长度为（4．7±1．5）mm，左颈总动脉与左锁骨下动脉之间的管壁长度为（7．9±2．6）mm，头臂干起始处至有锁骨下动脉开口处长度为（41．1±8．2）mm，左锁骨下动脉起始处至柞动脉开口处管腔长度为（38．5±5．7）mm，头臂干与左颈总动脉间距的平面与矢状面之间的夹角为（71．2±7．2）°，左颈总动脉与左锁’目’下动脉间距的平面与矢状面之间的夹角为（31．1±2．9）°。结论CT测量所得的胸主动脉数据可以为血管支架的生产提供支持，还能为腔内修复术中支架的定位释放提供指导。
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 length 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 ot： coronary artery （CA） was （35.7 ± 4.3 ） ram, 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） ram, the diameter of aortic arch between the LCCA and the left subclavian artery （LSA） was （27.6 ±4.2） ram, the diameter of descending aortic at the opening of the LSA was （25.4 ± 4.5 ） ram, 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. l ）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） ram, the length between the opening of BCT and the right subclavian artery （RSA） was （41.1 ± 8.2） ram, 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.
