ABSTRACT
BACKGROUND: This study was investigated risk factors of abdominal aortic aneurysm that correlation with an aortic diameter and necessity of ultrasonographic screening program through ultrasonographic examination of the aorta, additionally investigated prevalence of abdominal aortic aneurysm. METHODS: We conducted a prospective study of an aorta-proximal part, middle part, distal part with using abdominal ultrasography with 246 subjects more than 65 years old who visited the emergency department of chuncheon sacred hospital without symptoms during the period March 2004-February 2005. Also, examined risk factors (age, sex, smoking, hypertension, vascular disease) and did comparative analysis of relation between an aortic diameter and risk factors. RESULTS: The abdominal aortic diameter of them was 2.08+/-0.37cm in proximal part, 1.78+/-0.31cm in middle part, 1.55+/-0.31cm in distal part. The difference between male and female group was regarded(proximal part 2.20+/-0.35cm vs 1.99+/-0.36cm, the middle part 1.88+/-0.30cm vs 1.69+/-0.31cm, distal part 1.66+/-0.30cm vs 1.48+/-0.29cm). The difference of diameter in distal part was regarded in comparison of young old man and old old man (1.58+/-0.31cm vs 1.91+/-0.27cm). The difference of middle and distal aortic diameter between a smoking and non-smoking group was regarded (1.88+/-0.31cm vs 1.74+/-0.31cm, 1.62+/-0.32cm vs 1.53+/-0.30cm). The difference of distal aortic diameter between a hypertensive and non-hypertensive group(1.58+/-0.36cm vs 1.54+/-0.28cm) and between the groups which had a vascular disease or not(1.78+/-0.36cm vs 1.54+/-0.30cm) was regarded. There was no abdominal aortic aneurysm among them. CONCLUSION: The diameter of distal part increased with more ages, in male, smoker, and person with hypertension and vascular disease. In this study, abdominal aortic aneurysm wasn't found.
