Figure legends
Fig 1. (A) 3D-CT revealed an open false with an enlarged false lumen, leading to total arch replacement with FET. (B) 3D CT (C) contrast-enhanced CT showed blood flow in the previously thrombosed false lumen and an enlargement of the false lumen diameter (Fig. 1(B)(C)).
Fig2 4D Flow MRI revealed accelerated flow from the true lumen to the false lumen at the distal end of the Frozen Elephant Trunk (A)axial image (B))3D-view, (C) An increase in wall shear stress at the site where the flow from the true lumen to the false lumen is reached.
Fig, 3 (A) (B) Aortic angiography showed high-velocity blood flow from the true lumen to the false lumen at the distal end of the stent graft. (C) TEVAR was performed for dSINE, resulting in the disappearance of blood flow into the false lumen, and the surgery was concluded (D) Postoperative CT showed thrombosis of the false lumen and a reduction in its diameter (Fig. 3D).
