Intrathoracic tracheal dimensions and shape changes in chronic obstructive pulmonary disease.

Abstract

Changes in intrathoracic tracheal dimensions and shape in patients with chronic obstructive pulmonary disease (COPD) are commonly noted, but the cause is not clear. This study reveals a significantly larger lateral tracheal diameter (LTD) in patients with COPD. The larger LTD has a significant positive linear correlation with a larger lateral chest diameter… (More)
