(A) Anatomic features. (AA = ascending aorta, right arch; DA = descending aorta, right side behind AA; DK = diverticulum of Kommerell; E = esophagus; LA = ligamentum arteriosum; LCC = left common carotid; LS = anomalous left subclavian; PA = pulmonary artery; RCC = right common carotid; RS = right subclavian; T = trachea.) (B) Surgical correction. Aortic arch divided beyond RS; lower suture line on DA at site of excision of DK; alternatively DK excision encompassed with excision of short segment of DA; Gore-Tex sling around AA limb and second rib; LS implanted into LCC; LA divided; Dacron graft from AA to DA below hilum.

4. Fig 3
(A) Chest computed tomography (CT) (axial image) of patient 2 demonstrating markedly compressed and displaced trachea from the aortic arch anomaly. (B) Chest CT (axial image) of patient 2 after operation demonstrating midline trachea of normal diameter. (T = trachea, E = esophagus.)

5. Fig 4
Chest computed tomography (axial image) of patient 4 demonstrating tracheal compression (teardrop configuration) from the aortic arch anomaly and the diverticulum of Kommerell (DK). The “teardrop” is reversed from what is seen bronchoscopically.

Chest computed tomography (axial image) of patient 4 after operation, demonstrating relief of tracheal compression and Gore-Tex sling around the ascending aorta and the second rib. (GS = Gore-Tex sling.)
