case_images: Preoperative computed tomography angiogram of the chest. A: Axial view showing a non-stenotic sub-cricoid trachea (arrow). B: Axial view at the thoracic level showing an annular stenotic distal segment of the trachea (arrow).

case_images: Carefully reviewing his preoperative imaging for TOF correction, a narrowing of the distal trachea seemed apparent (Figure 2A-2B).
case_images: Computed tomography angiogram of the chest. A: Coronal view showing a non-stenotic sub-cricoid trachea with a diameter of approximately 6.6 mm. B: Coronal view showing a stenotic distal segment of the trachea with a diameter of approximately 3.1 mm.

case_images: A subsequent contrast chest CT showed an annular stenotic segment of the trachea (Figure 3A-3B) from the level of the third thoracic vertebra to a T-shaped carina, with a reduction in tracheal diameter of more than 50%.
