Abstract
Aims and Objectives: COVID‑19 can lead to long‑term pulmonary sequelae, particularly in patients who experience severe disease requiring intensive care unit (ICU) admission. This study aimed to evaluate new and residual lung computed tomography (CT) scan abnormalities in COVID‑19 ICU survivors at least six months after discharge and to identify demographic factors associated with these chronic radiological findings. Methods: This cross‑sectional study included 51 adult COVID‑19 survivors with a history of ICU admission at Valiasr Hospital in Zanjan, Iran, during 2021. Participants were evaluated at least six months after discharge. Demographic and clinical data were collected from medical records. High‑resolution CT (HRCT) scans were obtained to assess parenchymal, airway, and pleural abnormalities, which were interpreted by a pulmonologist. Statistical analyses included Chi‑square, Fisher’s exact test, independent t‑test, Mann–Whitney U, ANOVA, and Kruskal–Wallis tests, with a significance level of P-value < 0.05. Results: Ground‑glass opacity (GGO) was the most frequent abnormality (94.1%), followed by pleural thickening (82.4%), bronchiectasis (52.9%), emphysema (49%), and interlobular septal thickening (33.3%).
