RESUMEN
Este proyecto presenta una metodología basada en Dinámica de Fluidos Computacional, para el análisis del riesgo de rotura en aneurismas aórticos abdominales. Los métodos convencionales basados en características físicas del aneurisma pueden ser insuficientes para determ inar con precisión la ubicación de la ruptura en casos específicos. Por ello, es necesario adoptar enfoques más avanzados, para comprender las complejas dinámicas biomecánicas y hemodinámicas que afectan la estabilidad de la pared arterial. Se desarrolló un modelo tridimensional de la aorta abdominal, configurando parámetros geométricos y de flujo. Se evaluaron distintas etapas del crecimiento del aneurisma, desde una condición saludable hasta alcanzar un diámetro de 60 mm. El proceso incluyó simulaciones del comportamiento del flujo sanguíneo y de las tensiones mecánicas en las paredes arteriales. Los resultados mostraron que el incremento en el diámetro del aneurisma intensifica notablemente las tensiones mecánicas y los gradientes de presión. En estapas avanzadas se identificaron patrones de flujo turbulento que aumentan el riesgo de formación de trombos y la posible ruptura de la pared arterial.

ABSTRACT
This project presents a methodology based on Computational Fluid Dynamics (CFD) for analyzing the rupture risk in abdominal aortic aneurysms (AAAs). Conventional methods that rely solely on geometric and physical characteristics of the aneurysm may be insufficient for accurately predicting rupture in specific cases. Therefore, more advanced approaches are required to better understand the complex biomechanical and hemodynamic interactions that influence arterial wall stability. A three-dimensional model of the abdominal aorta was developed, incorporating geometric and flow-related parameters. Various stages of aneurysm progression were analyzed, ranging from a healthy condition to a maximum diameter of 60 mm. The study involved simulations of blood flow behavior and mechanical stress distribution on the arterial walls. Results demonstrated that as the aneurysm diameter increases, mechanical wall stresses and pressure gradients intensify significantly. In advanced stages, turbulent flow patterns were identified, which elevate the risk of thrombus formation and potential arterial wall rupture.
