It is known in patients with type B aortic dissection, WSS(Wall Shear Stress) is generally higher in the true lumen than in the false lumen, and aortic WSS is significantly higher in patients with a rapidly expanding false lumen. This study aimed to predict hemodynamic changes in the false lumen after primary entry closure by thoracic endovascular aortic repair. They performed a blood flow simulation with computational fluid dynamics (CFD). The result shows that high wall shear stress was seen at the expanded site in the false-lumen.
