In this study, we analyzed epidemiologic characteristics and morphologic differences between Asian and European population in patients with abdominal aorta aneurysm (AAA). Method:We conducted concomitant study in Japan and Europe , in 31 Asian patients (AP) with AAA and 130 control subjects of the same population, and in 30 European patients with AAA and 126 control subjects (EP). We observed various demographic and anthropologic parameters. Aortography was performed in all patients at the same type of CT-scanners using the same examination protocol and postprocessing. For data analysis, various statistical models were used. Results: There are statistically significant differences in multiple epidemiologic and morphologic findings in AAA patients, as well as in comparison with controls in both groups. This is most distinct in terms of anthropologic characteristics and number of risk-factors, and in terms of morphologic findings, in the length of neck of the aneurysm,transverse diameter of abdominal aorta (AA) and common iliac artery (c.i.a), and volumes of c.i.a. We obtained paradoxical results considering diabetes mellitus, which presented itself as a protective factor for AAA. Conclusion: Demographic-epidemiologic analysis accompanied with morphologic measurements using modern imaging modalities enables obtaining new information on pathology of AAA in different races. There are differences in number of risk-factors, and in terms of morphologic findings, in the length neck, angle of the aneurysm, transverse diameters of abdominal aorta (AA) and in the length of common iliac artery (c.i.a), and volume of c.i.a.
