Numerical modeling and simulations of type B aortic dissection treated by stent‐grafts with different oversizing ratios

Retrograde type A dissection after thoracic endovascular aortic repair has been a major drawback of endovascular treatment. This study investigated the biomechanical mechanism of stent‐graft‐induced new lesions after implantation and analyzed the relationship between radial force and spring‐back force of the stent‐graft when it was implanted virtually under different oversizing ratios. Based on the computed tomography angiography images, a...
