Abstract

OBJECTIVE

To study the anatomical characteristics about ascending aortic and aortic arch in Chinese population by CT.

METHODS

From September 2006 to September 2007, 388 patients free of current known aortic pathology undergone thoracic aorta CTA. The diameter of ascending aorta, aortic arch, and branch vessels of aortic arch were measured respectively by AW4.2 work station. The data base about all the measurements was set up. The CHISS statistical software was used to analysis data.

RESULTS

The aortic diameter above coronary artery (CA), the level at origin of and brachiocephalic trunk (BCT), the halfway of the ascending aorta, the level at origin of left common carotid artery (LCCA), the level at origin of left subclavian artery (LSA) and the level at distal of origin of LSA respectively were (34 +/- 5) mm, (34 +/- 5) mm, (33 +/- 4) mm, (30 +/- 4) mm, (28 +/- 3) mm and (26 +/- 3) mm. The diameters of two level between the origin of BCT and right subclavian artery (RSA) were (13.1 +/- 1.9) mm and (12.8 +/- 2.3) mm. Diameters of two level at LCCA were (8.7 +/- 1.5) mm and (7.9 +/- 1.0) mm. The diameters of two level between the origin of LSA and left vertebral artery were (10.7 +/- 1.7) mm and (9.3 +/- 1.3) mm. The aortic lumina length between the origin of CA and BCT was (5.3 +/- 1.2) cm, the aortic lumina length between the origin of BCT and LCCA was (1.3 +/- 0.4) cm, the lumen length between origin of BCT and RSA was (4.1 +/- 0.8) cm, the lumen length between origin of LSA and left vertebral artery was (3.8 +/- 0.8) cm. The distance between the wall of BCT and LCCA was (0.4 +/- 0.2) cm, the distance between the wall of LCCA and LSA was (0.7 +/- 0.6) cm.

CONCLUSIONS

Modular branched stent-graft system is fit for most part of the Chinese. The size fit for human could be got on this basic.

摘要

目的

通过CT研究中国人群升主动脉和主动脉弓的解剖学特征。

方法

2006年9月至2007年9月，对388例无已知主动脉病变的患者进行胸主动脉CT血管造影（CTA）。利用AW4.2工作站分别测量升主动脉、主动脉弓及其分支血管的直径，建立所有测量数据的数据库，采用CHISS统计软件进行数据分析。

结果

冠状动脉（CA）上方、头臂干（BCT）起始处、升主动脉中点、左颈总动脉（LCCA）起始处、左锁骨下动脉（LSA）起始处及LSA起始远端水平的主动脉直径分别为（34±5）mm、（34±5）mm、（33±4）mm、（30±4）mm、（28±3）mm和（26±3）mm。BCT起始处与右锁骨下动脉（RSA）之间两个水平的直径分别为（13.1±1.9）mm和（12.8±2.3）mm。LCCA两个水平的直径分别为（8.7±1.5）mm和（7.9±1.0）mm。LSA起始处与左椎动脉之间两个水平的直径分别为（10.7±1.7）mm和（9.3±1.3）mm。CA起始处与BCT之间的主动脉管腔长度为（5.3±1.2）cm，BCT起始处与LCCA之间的主动脉管腔长度为（1.3±0.4）cm，BCT起始处与RSA之间的管腔长度为（4.1±0.8）cm，LSA起始处与左椎动脉之间的管腔长度为（3.8±0.8）cm。BCT与LCCA管壁之间的距离为（0.4±0.2）cm，LCCA与LSA管壁之间的距离为（0.7±0.6）cm。
