Abstract
INTRODUCTION: COVID-19 Patients may be at risk for involving with spontaneous pneumothorax. However, clinical data are lacking in this regard. In this study, we aimed to investigate the demographic, clinical, and radiological characteristics and survival predictors in COVID-19 patients with pneumothorax. METHODS: This is a retrospectivestudy conducted on COVID-19 patients with pneumothorax that had been hospitalized at hospital. l from December 2021 to March 2022. The chest computed tomography (CT) scan of all patients was reviewed by an experienced pulmonologist in search of pulmonary pneumothorax. Survival analysis was conducted to identify the predictors of survival in patients with COVID-19 and pneumothorax. RESULTS: A total of 67 patients with COVID-19 and pneumothorax were identified. Of these, 40.7% were located in the left lung, 40.7% were in the right lung, and 18.6% were found bilaterally. The most common symptoms in the patient with pneumothorax were dyspnea (65.7%), increased cough severity (53.7%), chest pain (25.4%), and hemoptysis (16.4%). The frequency of pulmonary left and right bullae, pleural effusion, andfungus ball were 22.4%, 22.4%, 22.4%, and 7.5%, respectively. Pneumothorax was managed with chest drain (80.6%), chest drain and surgery (6%), and conservatively (13.4%). The 50-day mortality rate was 52.2% (35 patients). The average survival time for deceased patients was 10.06 (2.17) days. CONCLUSIONS: Our results demonstrated that those with pleural effusion or pulmonary bullae have a lower survival rate. Further studies are required to investigate the incidence and causality relation between COVID-19 and pneumothorax.
