The Effect of Tracheal Diverticulum and Chronic Ostructive Lung Disease on Chest Anthropometry

Abstract

Aim: In this study, we aimed to evaluate the effect of tracheal diverticula (TD) on chest anthropometry and its relationship with chronic obstructive pulmonary disease (COPD). Material and Method: Between January 2019 and March 2020, 995 patients who underwent chest CT were retrospectively analyzed and TD was detected in 62 cases. Group 1 is only TD, Group 2 is TD + COPD, Group 3 is only COPD, Group 4 is defined as control group. We measured the localization, size, the distance to carina and vocal cord of TDs. In all groups chest diameters at T4 and T9 levels were measured as transverse and vertical plans. Results: TDs detected mostly at the T2 and T3 levels. In Group 1 and Group 2, there was a statistically significant difference the distance to TD of vocal chords. A statistically significant difference was found between Group 1 and Group 3 only in the anteroposterior diameter at the T4 and T9 levels.Conclusion: The fact that TDs, which we do not know clearly whether they are acquired or congenital, have different TD levels in COPD patients made us think that TDs may be acquired. We also observed that COPD affects TD localization and TD has the opposite effect in increasing anteroposterior chest parameters in COPD. Precence of TD is essential on COPD patients about thorax anthropometry.
