ABSTRACT
Tracheomegaly (TM) is a rare appearance that is radiologically defined as an excessive enlargement of the tracheal diameter. We present a comprehensive analysis of tracheal diameter measurements and TM incidence in patients admitted and treated due to COVID-19 pneumonitis and its association with possible respiratory complications. In this retrospective study, we included 1015 patients divided into three groups 383 patients treated using mechanical ventilation (MV), 132 patients treated using high-flow ventilation (HFV), and 500 randomly selected patients using nasal catheter (NC) oxygenation. The tracheal lumen diameter was measured continuously using a chest X-ray, and the cuff/trachea (C/T) diameter ratio was calculated. We detected TM in 71 patients (18.54%). Regression analysis showed statistical significance in MV patients for the trachea diameter at the level of the cuff, maximal trachea diameter and C/T diameter ratio, and days on MV. Respiratory complications showed a significant association with the C/T diameter ratio. The C/T diameter ratio was shown to be a reliable potential predictor of the occurrence of respiratory complications. The results of the study highlight the importance of the early detection and prevention of TM in COVID-19 patients on MV using a chest X-ray and measurement of the C/T diameter ratio.
