We measured the widest anteroposterior diameters of the thoracic and abdominal aortas of 350 patients without cardiovascular diseases who had undergone computerized tomography of the thorax and/or abdomen. After classifying them according to gender and age group, we calculated the mean diameters and standard deviations, and determined the ratios between the ascendant and descendent thoracic aortic diameters, and of the abdominal aorta, concluding that: both the thoracic and abdominal aortic diameters are reduced from their proximal to their distal portions; the body surface influences the size of the aorta; vessel diameters was observed to gradually increase with age; men were found to have larger diameters than age matched women; the ratio between the ascending and descending aortic diameters varies according to gender and age; the relations between abdominal aortic diameters measured at the level of renal hila and cephalad to the bifurcation areindepend from gender and age; but, the relation between those measured at the level of the superior mesenteric artery and cephalad to the bifurcation are linked to gender, but not to age.
我们测量了350例无心血管疾病且接受过胸部和/或腹部计算机断层扫描患者的胸主动脉和腹主动脉的最大前后径。在根据性别和年龄组对他们进行分类后，我们计算了平均直径和标准差，并确定了升主动脉和降主动脉直径之间以及腹主动脉直径之间的比率，得出以下结论：胸主动脉和腹主动脉直径从近端到远端均逐渐减小；体表影响主动脉大小；观察到血管直径随年龄逐渐增加；发现男性的直径大于年龄匹配的女性；升主动脉和降主动脉直径之间的比率因性别和年龄而异；在肾门水平及分叉上方测量的腹主动脉直径之间的关系与性别和年龄无关；但是，在肠系膜上动脉水平及分叉上方测量的腹主动脉直径之间的关系与性别有关，但与年龄无关。
