To generate reference values of the normal areas of the abdominal aorta at various levels among Chinese people and to explore the factors that may promote the expansion of the abdominal aorta.
The areas of normal abdominal aortas were gauged at various levels based on inner-to-inner measurements in 1,066 Chinese adult patients (>18 years) without the abdominal aortic disease. The areas of subphrenic abdominal, suprarenal abdominal, infrarenal abdominal, and distal abdominal aortas were measured. The demographic and clinical characteristics were collected into a specifically designed electronic database. Multivariable linear regression was used to analyze the potential risk factors promoting the expansion of the abdominal aorta.
In males, the median areas of the subphrenic abdominal aorta, suprarenal abdominal aorta, infrarenal abdominal aorta, and distal abdominal aorta were 412.1, 308.0, 242.2, and 202.2 mm, respectively. In females, the median areas of the subphrenic abdominal aorta, suprarenal abdominal aorta, infrarenal abdominal aorta, and distal abdominal aorta were 327.7, 243.4, 185.4, and 159.6 mm, respectively. The areas of the abdominal aorta at different levels were larger in males than in females and increased with age. Multiple linear stepwise regression analysis showed that the subphrenic abdominal aortic area was significantly related to age (β = 0.544, < 0.001), sex (β = 0.359, < 0.001), and hypertension (β = 0.107, < 0.001). Suprarenal abdominal aortic area was related to age (β = 0.398, < 0.001), sex (β = 0.383, < 0.001), history of smoking (β = 0.074, = 0.005), and hypertension (β = 0.111, < 0.001). The infrarenal abdominal aortic area was correlated with age (β = 0.420, < 0.001), sex (β = 0.407, < 0.001), and history of smoking (β = 0.055, = 0.036). The distal abdominal aortic area was correlated with age (β = 0.463, < 0.001), sex (β = 0.253, < 0.001), and hypertension (β = 0.073, = 0.013).
The abdominal aortic areas at different levels were larger in males than in females. Aging, hypertension, and smoking prompt the expansion of abdominal aorta.
获取中国人腹主动脉不同水平的正常面积参考值，并探讨可能促使腹主动脉扩张的因素。
对1066例无腹主动脉疾病的中国成年患者（>18岁）进行腹主动脉内径测量，以此来测定不同水平正常腹主动脉的面积。测量了膈下腹主动脉、肾上腺上腹主动脉、肾下腹主动脉和腹主动脉远端的面积。将人口统计学和临床特征收集到专门设计的电子数据库中。采用多变量线性回归分析促使腹主动脉扩张的潜在危险因素。
男性膈下腹主动脉、肾上腺上腹主动脉、肾下腹主动脉和腹主动脉远端的中位面积分别为412.1、308.0、242.2和202.2平方毫米。女性膈下腹主动脉、肾上腺上腹主动脉、肾下腹主动脉和腹主动脉远端的中位面积分别为327.7、243.4、185.4和159.6平方毫米。不同水平的腹主动脉面积男性大于女性，且随年龄增长而增加。多元线性逐步回归分析显示，膈下腹主动脉面积与年龄（β = 0.544，<0.001）、性别（β = 0.359，<0.001）和高血压（β = 0.107，<0.001）显著相关。肾上腺上腹主动脉面积与年龄（β = 0.398，<0.001）、性别（β = 0.383，<0.001）、吸烟史（β = 0.074，=0.005）和高血压（β = 0.111，<0.001）有关。肾下腹主动脉面积与年龄（β = 0.420，<0.001）、性别（β = 0.407，<0.001）和吸烟史（β = 0.055，=0.036）相关。腹主动脉远端面积与年龄（β = 0.463，<0.001）、性别（β = 0.253，<0.001）和高血压（β = 0.073，=0.013）相关。
不同水平的腹主动脉面积男性大于女性。衰老、高血压和吸烟会促使腹主动脉扩张
