Figure 1
Figure 1 Preoperative chest computed tomography scanning at the local hospital. Space occupying and calcification within the lumen of the thoracic aorta were observed.
Figure 2
Figure 2 Preoperative computed tomography angiography. A: The thrombus originated from the lesser curve of the aortic arch, and its distal part was floating; B: Calcified plaques and hematoma (arrow a) located at the aortic wall, and some calcified plaques were within the floating thrombus; and C: A pedicle (arrow b) connected the floating thrombus to the adjacent aortic wall.
Figure 3
Figure 3 The three dimensional printed model of the aorta and floating thrombus. A: The thrombus and adjacent aortic wall were linked along the long axis; B: A longitudinal flap (arrow a) linked the floating thrombus and the adjacent aortic wall; and C: The three dimensional-printed model revealed a defect in the adjacent aortic wall (arrow b).
