Abstract

Abdominal Aortic Aneurysm is caused by changes to the blood flow pattern due to the change of the elasticity and shape of the blood vessel. This type of aneurysm had been placed at the 10th highest cause of deaths of white males aged between 65 and 74 in the U.S.A, in the year of 2000.(National Center for Health Statics) Abdominal Aortic Aneurysm is generated due to the unbalance of the enzyme which controls the aortic wall. The continuing expansion of the aortic wall drastically increases due to the mechanical quality change of the vessel. And ruptures occur, ultimately. The cause of aneurysm has not been known exactly yet, but smoking is being given attention as the largest cause. And other causes are hypertension, family history and gender in statistically. This study analyzes blood flow patterns and observed the movement changes according to the diameter of the abdominal aortic aneurysm. It was confirmed that as the expansion part gets larger, the blood flow focuses on the top of the expansion part. And the flow velocity at the bifurcation point which connects to the common iliac artery increases. In this study, we tried to specify the process element of the abdominal aortic aneurysm based on the analysis results, that the increase of the expansion part due to the aneurysm was viewed as change of the blood flow.
