A Single-Center Experience on the Treatment Outcomes of Patients with COVID-19-Pleural Disorders: Lessons for the Future.

Background: Pleural disorders in novel coronavirus disease 2019 (COVID-19), responsible for the deaths of more than 6.7 million people worldwide, are relatively uncommon and underappreciated findings. The severity of the pleural disease in these patients correlates with the treatment outcome and overall prognosis. Objective: We aim to review our experience with treatment modalities and prognosis in 45 patients with COVID-19, who were treated at our Clinic between April 2020 and October 2021. Methods: We conducted a retrospective, single-center, cross-sectional study. Demographic data, the type of thoracosurgical intervention(s), and treatment outcome for 45 patients included in this study were recorded for every patient. We analyzed the type and number of treatment modalities according to the pleural disorder, and the outcome of the treatment. Results: Pneumothorax was the most common COVID-19-related pleural disorder, followed by the pleural effusion. Tube thoracostomy was the mainstay of treatment, performed in 84.4% of patients with unilateral pleural complications. In total, 20% of our patients were on mechanical ventilation, and all of them had a fatal outcome. We found statistical significance in comparison to the percentage of fatal outcomes between patients treated with and without mechanical ventilation (p=0.000). Conclusion: COVID-19-related pleural disorders are prognostic markers of disease progression. Mechanically ventilated patients who require tube thoracostomy have an unfavorable prognosis.
