Outline of Final Research Achievements |
We have analyzed the fragility (rupture risk) of the aortic aneurysm with our original model. Saccular aneurysm is known to have potential risk of rupture, but the definition of “saccular” has not been determined. We put the hypothetical ellipse on the protruded aneurysm from the aorta, and revealed that the horizontally long ellipse and the vertically long with smaller fillet radius are the factors relating to the rupture risk and concluded these are important factors contribute to the definition of “saccular”. Although we used these definition on the thoracic aortic aneurysm cases by using the enlargement rate, we were not able to reveal the clear association clinically. Herein, we collected rupture cases of abdominal aortic aneurysms and analyzed them via propensity matching comparing to the control group in our institutes. Two factors, vertically long and horizontally long with small fillet, showed strong association with the rupture.
