Flow structures and wall shear stress patterns in the thoracic aorta
Wednesday, June 5, 2013 - 9:00am - 9:45am
Thoracic endovascular aortic repair (TEVAR) has become widely accepted as an important option for treatment of thoracic aortic diseases. Many studies have proven the safety and efficacy of TEVAR with satisfactory short-term to mid-term outcomes. Nevertheless, even if the initial TEVAR treatment technically succeeds, some patients show recurrence and progression of disease many years after treatment. Based on long-term follow-up examinations, it has been inferred that such long-term morphological changes and hemodynamics interact with positive feedbacks. The wall shear stresses show different patterns depending on the original aorta morphologies. In this talk, the relationship between them will be discussed using patient-specific models of the thoracic aorta as constructed from CT scans.
