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.
