Editorial

Acute respiratory distress syndrome (ARDS), the most common and severe complication in COVID-19 patients requires ventilation and oxygen therapies.1 A previous study from China indicated that invasive mechanical ventilation (IMV) was required between 9.8 and 15.2 % of the patients.2 Median duration of mechanical ventilation of 17 days and high frequent re-intubation were found in COVID-19 patients.3,4 Several previous studies lastly revealed the association between obesity (a proven risk factor for benign subglottic/tracheal stenosis (SG/TS) and required-IMV-COVID-19 patients.5 Approximately, 10-22 % of non-COVID-19 patients were reported of SG/TS.6 Currently, experiences in SG/TS in COVID-19 scenario are still not demonstrated.1 Hypothetically, after extubation, a SG/T cicatricial concentric stenosis (Figure 1)1 in a number of these patients, including long-COVID-19 will be developed and differential diagnosis of SG/TS with other pulmonary or tracheobronchial diseases could be significantly played by high-resolution-computed tomography (HRCT) (Figure 2).6,7 Consensus about the best therapy strategy for SG/TS is still not developed.1

Conclusion

In conclusion, in recovered COVID-19 patients with breathing difficulties after mechanical ventilation weaning should be highlighted suspecting tracheal stenosis (SG/TS), whereas the management is similar to general tracheal stenosis.
