Chest X-ray revealed scoliosis (Figure 1), and laryngoscopy showed neither supraglottic stenosis nor edema.
Chest computed tomography. Computed tomogram before the operation shows extrinsic compression of the trachea by the innominate artery. (A) Superior vena cava; (B) manubrium; (C) innominate artery; (D) trachea.

Chest computed tomography (CT) revealed tracheal stenosis caused by compression by the innominate artery (Figure 2).
Bronchoscopy. Bronchoscopy shows narrowing of the trachea by a pulsatile compression on the anterior tracheal wall (white arrow).

fig3
Bronchoscopy demonstrated narrowing of the trachea by external compression of its anterior wall as well as tracheomalacia (Figure 3) involving the middle trachea to the tracheal bifurcation.
3D CT. Three-dimensional CT shows the innominate artery (white arrow) crossing the trachea from left to right just cranial to the manubrium.

Willis with no occlusion of the internal carotid or innominate arteries. 3D CT demonstrated that the innominate artery crossed the trachea from left to right just cranial to the manubrium (Figure 4). We planned prophylactic ligation of the innominate artery to prevent the formation of TIF.
Intraoperative view. The innominate artery (white arrow) was isolated and taped proximally and distally.

The innominate artery was exposed anterior to the trachea (Figure 5).
