Vascular ultrasound evaluation of the abdominal aorta is a simple and efficient technique for assessing the morphology and size of the abdominal aorta, as well as for identifying infrarenal aortic aneurysms, a potential condition with significant mortality.
This study aims to evaluate the diameter and morphology of abdominal aorta in a community-based population using vascular ultrasound and to determine the prevalence of infrarenal aortic aneurysms.
A randomized sample of individuals aged 60 years and above was recruited from several provinces. Abdominal aortic diameters were measured using vascular ultrasound according to established international guidelines.
810 individuals were enrolled in the study, of whom 40.2% were male, with a mean age of 70.9 ± 7.56 years. The mean infrarenal abdominal aortic diameter was 18.2 ± 2.93 mm in men and 16.3 ± 1.87 mm in women (p < 0.001). A significant increase in aortic diameter was observed with advancing age. Age, male sex, body surface area, and current smoking status were significant predictors of infrarenal aortic diameter.
In this population-based survey, the mean infrarenal abdominal aortic diameter was 18.2 ± 2.93 mm in men and 16.3 ± 1.87 mm in women, with an infrarenal aortic aneurysm prevalence of 0.12%. Further population-based studies with a bigger sample and extended follow-up are necessary to investigate further the aortic morphologies predisposing to later aneurysm.
腹主动脉的血管超声评估是一种简单有效的技术，可用于评估腹主动脉的形态和大小，以及识别肾下腹主动脉瘤，这是一种具有较高死亡率的潜在疾病。
本研究旨在使用血管超声评估社区人群腹主动脉的直径和形态，并确定肾下腹主动脉瘤的患病率。
从几个省份招募了60岁及以上的随机样本个体。根据既定的国际指南，使用血管超声测量腹主动脉直径。
810人参与了该研究，其中40.2%为男性，平均年龄为70.9±7.56岁。男性肾下腹主动脉平均直径为18.2±2.93mm，女性为16.3±1.87mm（p<0.001）。随着年龄的增长，主动脉直径显著增加。年龄、男性性别、体表面积和当前吸烟状况是肾下腹主动脉直径的重要预测因素。
在这项基于人群的调查中，男性肾下腹主动脉平均直径为18.2±2.93mm，女性为16.3±1.87mm，肾下腹主动脉瘤患病率为0.12%。有必要进行更大样本量和更长随访期的进一步基于人群的研究，以进一步调查易患后期动脉瘤的主动脉形态。
