Our study was conducted by consulting angioCT sites made on a CT GE LightSpeed VCT64 Slice CT and a CT GE LightSpeed 16 Slice CT, following the path and relationships of the descending thoracic aorta against the vertebral column, outside diameters thereof at the thoracic vertebrae T4, T7, T12 and posterior intercostal arteries characteristics. The origin of of the descending thoracic aorta we found most commonly on the left flank of the lower edge of the vertebral body T4, but I have encountered cases where it had come above the lower edge of T4 on level of intervertebral disc T4-T5 or even at the upper edge of T5 vertebral body. At thoracic vertebra T4, on a total of 30 cases, the descending thoracic aorta present a diameter of 20.0 to 32.6 mm, values that correspond to male gender and to females diameter ranging from 25.5 to 27, 4 mm. At level of T7 thoracic vertebra, thoracic aorta present a diameter of 19.6 to 29.5 mm, values found in men, in women the diameter being from 21.9 to 25.2 mm. At thoracic vertebra T12, on a total of 27 cases, the descending thoracic aorta present a diameter of 17.6 to 27.7 mm, in males the diameter was from 17.6 to 27.7 mm and females diameter ranging from 21.1 to 25.2. The length of the descending thoracic aorta was from 18.40 to 19.41 cm.

Our study was conducted by the evaluation of angioCT’s performed on a GE LightSpeed VCT64 Slice CT Scanner. The measurements were performed on the aortic arch at the following levels: at the origin of the aorta, the middle part of the ascending aorta, prior to the origin of the brachiocephalic arterial trunk and after the origin of the left subclavian artery. We measured the caliber of the aortic arch arteries and the data are correlated and reported by gender. The diameter of the ascending aorta was between 27 to 28.9 mm in females and in males from 25.8 to 37.6 mm. The diameter of the aorta within the middle segment of the ascending part was between 28-30.2 mm in females and in males from 26.1 to 34.6. The diameter of the aortic arch prior to the origin of the brachiocephalic arterial trunk was between 26.4 to 29.4 mm in females and in males from 25.8 to 37.5 mm. The diameter of the aortic arch after the origin of the left subclavian artery was in a range of 20.4 to 28.4 mm, which corresponds to the limits found in males while in females the aortic diameter was between 21.3 to 24.1 mm. The brachiocephalic trunk diameters were 8.3 to 15.5 mm in females and in males was 9.1 to 14.5 mm. The right common carotid artery had a diameter of 4-8 mm diameter in males and in females ranged from 4.7 to 5.5 mm. The right subclavian artery showed a caliber of 5.7 to 7.5 mm in females and in males from 5.9 to 10.1. The left common carotid artery diameter was 4.6 to 5.7 mm in females and males the diameter was between 5.2 to 7.4 mm. The left subclavian artery had a diameter of 6-10 mm in females and in males ranged from 7.7 to 12.8 mm. We found that the distance between the ascending part of the aorta and the descending segment ranged from 33.3 to 38.5 mm in females and in males from 40 to 68.6 mm. We measured the distance that exists at the crossing of the aortic arch with the left branch of the pulmonary trunk, finding that in females this distance is 3 to 10.3 mm and in males from 3 to 12.5 mm.

Our study was conducted by the examination of angioCT’s, performing external measurements of aortic arch and the exo and endoaortic measurements of its three. The diameter of the thoracic aorta prior to the origin of the brachiocephalic arterial trunk was found with an average of 31.65 mm and below the left subclavian artery origin we found an average diameter of 24.3 mm. The brachiocephalic arterial trunk had an average diameter of 11.575 mm, 6.05 at carotid artery level and 9.05 mm at the level of the left subclavian artery. The endoaortic average diameter of the brachiocephalic arterial trunk: horizontally, 13.0 mm and vertically 11.7 mm; left common carotid artery horizontal diameter was 10.5 mm and 9.7 mm vertically and the left subclavian artery have 14.1 mm horizontally and 10.8 mm vertically.
