The aim of this study was to establish normal diameters for the suprarenal and infrarenal abdominal aorta measured at T12 and L3 vertebral levels in the Indian population and to study the variation in aortic diameters with age, sex, height, weight, body mass index (BMI), and body surface area (BSA).
One hundred and forty-two patients who underwent helical contrast-enhanced computed tomography (CT) scans of the abdomen for non-cardiovascular reasons were recruited.. The mean internal diameters of the suprarenal and infrarenal abdominal aorta (maximum anteroposterior and transverse diameter) were measured at T12 and L3 vertebral levels and tabulated according to various age groups for both men and women. Pearson correlation coefficient was used to evaluate the correlation between aortic diameters, height, weight, BSA, and BMI.
The mean diameters of the suprarenal and infrarenal abdominal aorta measured at T12 and L3 vertebral levels, in men were 19.0 ± 2.3 and 13.8 ± 1.9 mm and in women 17.1 ± 2.3 and 12.0 ± 1.6 mm, respectively. The aortic diameter progressively increased in caliber with increasing age of the patients and was smaller in women than men. A significant positive correlation was found in men between the suprarenal and infrarenal aortic diameters and weight, BSA, and BMI. In women, this correlation was significant in the infrarenal aorta but not in the suprarenal aorta.
We obtained a set of normal values for the abdominal aorta in the Indian population. The aortic diameters correlated with age, gender, and body size of the patients as seen with previously published data in the Western population. A brief comparison of data between Indian and Western population showed that the values obtained were less than published elsewhere and hence, this should be considered while formulating intervention protocols.
本研究的目的是确定印度人群中在T12和L3椎体水平测量的肾上腺上方和肾下腹主动脉的正常直径，并研究主动脉直径随年龄、性别、身高、体重、体重指数（BMI）和体表面积（BSA）的变化。
招募了142例因非心血管原因接受腹部螺旋增强计算机断层扫描（CT）的患者。在T12和L3椎体水平测量肾上腺上方和肾下腹主动脉的平均内径（最大前后径和横径），并按不同年龄组对男性和女性进行列表。采用Pearson相关系数评估主动脉直径、身高、体重、BSA和BMI之间的相关性。
在T12和L3椎体水平测量的肾上腺上方和肾下腹主动脉的平均直径，男性分别为19.0±2.3和13.8±1.9mm，女性分别为17.1±2.3和12.0±1.6mm。主动脉直径随着患者年龄的增加而逐渐增大，女性的直径小于男性。在男性中，肾上腺上方和肾下腹主动脉直径与体重、BSA和BMI之间存在显著正相关。在女性中，这种相关性在肾下腹主动脉中显著，但在肾上腺上方主动脉中不显著。
我们获得了印度人群腹主动脉的一组正常值。如西方人群先前发表的数据所示，主动脉直径与患者的年龄、性别和体型相关。印度和西方人群数据的简要比较表明，获得的值低于其他地方发表的值，因此，在制定干预方案时应考虑这一点。
