TAA14. A Computational Analysis of Different Methodologies for Revascularization of the Left Subclavian Artery

Overstenting of the left subclavian artery (LSA) in zone 2 thoracic endovascular aortic repair (TEVAR) may cause left arm ischemia and impede cerebral blood flow. To overcome this issue, two surgical options are available: (1) left common carotid artery (LCCA) to LSA bypass and (2) branched endovascular repair with LSA branched stent graft. This work studies the hemodynamic outcomes of both surgical approaches and the role of the circle of Willis anatomy using patient-specific computational fluid dynamics (CFD) analyses.
