NUMERICAL SIMULATION OF AORTIC DISSECTION: EVALUATING VIRTUAL SURGICAL INTERVENTIONS FOR IMPROVED HEMODYNAMIC OUTCOMES AND PERSONALIZED TREATMENT PLANNING

Abstract

Aortic dissection is a severe clinical condition that demands a thorough understanding of the interactions between the true and false lumens. In this study, numerical simulations were performed for two patients, generating two preoperative and two postoperative models. The analyses were carried out using the PAKSF solver, a specialized tool for fluid–structure interaction problems. The objective was to evaluate the influence of virtual surgical interventions by examining essential hemodynamic parameters, including shear stress, pressure, and flow velocity in both lumens. The findings indicate that virtual surgical modeling can serve as a valuable tool for surgical planning, providing improved insight into post-intervention hemodynamic alterations. Moreover, this methodology supports patient-specific treatment strategies, contributing to optimized outcomes. Overall, the results highlight the potential of numerical simulations in clinical practice, particularly for the management of complex vascular disorders.
