Aim: The aim of this paper was to find some elements involved in the development of the aortic aneurysms using a morphological and mechanical study of the aortic wall.
Methods: The morphological data obtained from the dissection of 60 not preserved corpses were completed by a histological and a mechanical study for the testing of the strength of the aortic wall with the computerized device “TIRA TEST 2161”. For the study, atheromatous aortas, nonatheromatous aortas and aortic grafts were used.
Results: The results were compared to important clinical statistics and they proved that: there is no connection between normal morphology of the aorta and the location of the aortic aneurysms; the frequency of the aneurysms is closely connected to the increasing number of the atheromas plaques from the origin of the aorta to fork; the atheromatous aortas have a higher degree of strength and the arch is the strongest; the nonatheromatous aortas are less resistant in tearing from the origin to the fork; the atheromatosis does not protect from tearing; the percentage of parietal elongation being the same in both studied categories shows that the parietal stress between the atheroma plaques is exceeding, with its deterioration in time; the junction area: normal aortic wall – atheroma plaque is a “weak zone” with an important part in the expansion mechanism and of the aneurysm tearing
Conclusion: We can state that this area is the beginning point of the aneurysm development.
