ABSTRACT

Objective: Identify pulmonary fibrosis by tomography in patients with a history of COVID-19 and evaluate their pulmonary evolution in one year in search of this finding. Methods: Cross-sectional, descriptive, retrospective, and observational study. Sample size 115 patients. Results: The present study included 124 patients, with an age range of 21 to 83 years, and an average of 50.1 years. There was a slight predominance of females (51%) over males (49%). The CORADS 5 category was the most frequent in 96.8% of the patients in the basal chest tomography, with predominant pattern type A in 63.7% of the cases, with a maximum of 25 points and a minimum of 2. At the 6-month tomographic control, 58.9% of the patients presented a normal tomography; in 25% of the patients, subpleural bands were observed as the most frequent fibrocicatricial finding. Conclusion: It was demonstrated that there is no significant correlation between the predominant pattern and the initial chest CT score with respect to fibrocystic changes; at 1 month, the predominant pattern of the initial study persisted, and at 6 months, most of the patients had a CT within normal parameters.
