tracheal stenosis

Säbelscheidentrachea
bei COPD: Die Trachea ist in der coronaren Ebene ggü. dem sagittalen Durchmesser deutlich verschmälert. Der extrathorakale Anteil wieder normal weit.

A case of
tracheal obstruction presenting as COPD. Transverse thoracic CT demonstrating a significant reduction in tracheal luminal diameter with the absence of any focal lung lesions, suggestive of a primary tumour. The oesophagus appears compressed. Mediastinal lymph nodes are not seen.

chronic stridor. Axial CT with contrast of the chest shows the left pulmonary artery arising from the right pulmonary artery and then coursing posterior to the trachea and anterior to the esophagus, causing focal narrowing of the trachea at this level.The diagnosis was pulmonary sling causing tracheal stenosis.

was difficult to intubate. Coronal CT without contrast of the chest shows the trachea to be narrowed over a length of 2 cm from the thoracic inlet downward. At its narrowest, the trachea measured only 2 mm in diameter. There was also narrowing of the proximal right mainstem bronchus at its origin.The diagnosis was tracheal stenosis.

Tracheal stenosis is usually acquired following intubation or tracheostomy. It can also arise as part of the spectrum of tracheobronchial stenosis.

Pathology

Inflammation and pressure necrosis of the tracheal mucosa most commonly occur at either the tracheostomy stoma or at the level of the tube balloon. Acute post-intubation stenosis results from mucosal edema or granulation tissue.

The stenosis is typically 1.5-2.5 cm in length. In patients with chronic stricture, tracheomalacia may result from weakness of tracheal cartilage and can be a cause of dyspnea.

Radiographic features

CT

Eccentric or concentric soft tissue thickening internal to normal-appearing tracheal cartilage may be visible. The outer tracheal wall has a normal appearance without evidence of deformity or narrowing. Expiratory CT shows little change in tracheal diameter.
