The Aneurysm is an expansion or distension of the wall of a blood vessel, however, this study is based on the abdominal aorta, a segment of the aorta that gives rise to the celiac trunk that divides into gastric arteries, liver and spleen. We designed physical model with the software Solidwokes. This software has allowed us to visualize the Abdominal Aortic Aneurysm, we have noticed an increase in the diameter of the aorta where less than 50% aver the normal aorta. The mathematical models of blood flow in the abdominal aorta aneurismed were made based on the exploitation of Navier Stokes equations, for the finite difference method and that of the law of conservation of momentum. These math modes show that in the Abdominal Aortic Aneurysm it has increase the upstream pressure of blood and decrease downstream.

Abstract: (french)
L’Anévrisme est une dilatation ou distension anormale de la paroi d'un vaisseau sanguin. Cependant, la présente étude se base à l’aorte Abdominale, un segment de l’Aorte qui donne naissance au tronc cœliaque qui se divise en artères gastriques, hépatique et splénique. Nous avons conçu son modèle physique avec le logiciel SolidWokes. Ce logiciel nous a permis de visualiser l’Anévrisme de l’Aorte Abdominale, nous avons remarqué une augmentation du diamètre de l’aorte d’au moins 50% par rapport à son diamètre normal. Les modèles mathématiques de l’écoulement sanguin dans l’aorte Abdominale anévrismée ont été réalisés sur base de l’exploitation des équations de Navier Stokes, par la méthode de différences finies et celle de la loi de conservation de l’impulsion. Ces modèles mathématiques ont démontré que dans l’Anévrisme de l’Aorte Abdominale il ya augmentation de la pression sanguine en amont et diminution en aval.
