The objective was to investigate the prevalence of abdominal aortic aneurysms (AAAs) and the diameters of the aorta and common iliac arteries (CIAs) in a Korean cohort and secondly to analyze the differences in aortic diameter by comparison with a European cohort. The Korean cohort included participants ≥ 50 years who consented to AAA screening and data were analysed retrospectively. Aortic and common iliac diameters were measured using the outer-to-outer diameter method and prevalence rates were calculated. Common risk factors such as smoking, body mass index, pulmonary disease, hypertension, diabetes, hyperlipidaemia, ischaemic heart disease, and cerebrovascular disease were reported in association with AAA occurrence and AAA development. The aortic diameters were then compared with those in a Belgian cohort of 2487 participants identified in the Liège AAA Screening Program. An aortic size index (ASI) was also calculated to account for the potential size differences in the Belgian and Korean populations. A total of 3124 Korean participants were examined using ultrasound. The prevalence of AAAs in this cohort was 0.7%. The combined prevalence of subaneurysmal dilatation and AAA was 1.5%. The prevalence in male smokers older than 65 years was 2.7% (19/715). The mean infrarenal aortic diameter was 17.3 ± 3.1 mm in men and 15.7 ± 2.7 mm in women; the corresponding values in Belgian participants were 19.4 ± 3.0 mm in men and 17.9 ± 2.4 mm in women. The median aortic size index was 0.99 (interquartile range 0.88-1.12). The mean infrarenal aortic diameter was significantly smaller in the Korean cohort than in the Belgian cohort. Considering the observed prevalence of AAAs in different age groups, the age groups which would contribute to most cases was male persons above 66 years in both cohorts.
目的是调查韩国队列中腹主动脉瘤（AAA）的患病率以及主动脉和髂总动脉（CIA）的直径，其次是通过与欧洲队列比较分析主动脉直径的差异。韩国队列包括同意进行AAA筛查的≥50岁参与者，并对数据进行回顾性分析。使用外径法测量主动脉和髂总动脉直径并计算患病率。报告了吸烟、体重指数、肺部疾病、高血压、糖尿病、高脂血症、缺血性心脏病和脑血管疾病等常见风险因素与AAA发生和发展的关系。然后将主动脉直径与列日AAA筛查项目中确定的2487名比利时参与者队列中的直径进行比较。还计算了主动脉大小指数（ASI），以考虑比利时和韩国人群中潜在的大小差异。共有3124名韩国参与者接受了超声检查。该队列中AAA的患病率为0.7%。亚动脉瘤样扩张和AAA的合并患病率为1.5%。65岁以上男性吸烟者中的患病率为2.7%（19/715）。男性肾下腹主动脉平均直径为17.3±3.1mm，女性为15.7±2.7mm；比利时参与者的相应值为男性19.4±3.0mm，女性17.9±2.4mm。主动脉大小指数中位数为0.99（四分位间距0.88 - 1.12）。韩国队列中的肾下腹主动脉平均直径明显小于比利时队列。考虑到不同年龄组中观察到的AAA患病率，两个队列中导致大多数病例的年龄组均为66岁以上男性。
