Abstract
Objective: In this study, the effect of tracheal diverticula (TD) on chest anthropometry and its relation with chronic obstructive pulmonary disease (COPD) was evaluated. Method: Between January 2019 and March 2020, 995 patients who underwent chest CT were retrospectively analyzed and TD was detected in 31 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 vertical diameter at the T4 and T9 levels. Conclusion: We observed that COPD effect TD location and also TD had opposite effect on anteroposteriorly increasing chest parameters in COPD. Precence of TD is essential on COPD patients about thorax anthropometry. Keywords: Tracheal diverticulum; antropometry; radiology; COPD; chest diameter
