Abstract

Background: Chest radiographs, spirometry and computed tomography scan are mainstay in the evaluation of patients with pulmonary disease. Patients with chronic obstructive pulmonary disease develops saber sheath trachea due to repetitive cartilaginous injury from excessive coughing and elevated intrathoracic pressure causing degeneration and ossification of the tracheal cartilage.6 This study is done to determine the correlation of chest radiograph tracheal index (Coronal tracheal diameter/Sagittal tracheal diameter) with COPD severity using the GOLD staging system.


Method: One-hundred and two patients diagnosed with Chronic Obstructive Pulmonary Disease (COPD) wherein spirometry and, posteroanterior and lateral chest radiograph were done within six months of each other were included in the study. GOLD staging system using spirometry and tracheal index using chest radiographs were determined.


Results: There is low correlation between chest radiograph tracheal index and COPD severity (r=-0.1074).


Conclusion: Among patients with COPD, there is very low correlation of chest radiograph tracheal index and severity of COPD, hence, this index obtained by chest radiograph may not be useful in assessing for severity of COPD.
