Utilizing numerical simulations to prevent stent graft kinking during thoracic endovascular aortic repair

Summary: Thoracic Endovascular Aortic Repair (TEVAR) is a minimally invasive technique for treating thoracic aorta pathologies. Computational models, such as finite element analysis, can be used to predict clinical procedure outcomes or conduct in-silico clinical trials. This study applies a validated TEVAR methodology to a patient-specific case and assesses the overall applicability of the TEVAR modeling using the ASME V&V40 protocol. Validation evidence sources are identified and adopted to demonstrate the reliability and applicability of the numerical procedure.
