Surgery for Aspergillus Empyema with Refractory Pleural Fistula Following COVID-19 Pneumonia after Temporizing Measure Using Endobronchial Watanabe Spigot: A Case Report
Abstract
ABSTRACT INTRODUCTION Approximately 20% of patients who contract coronavirus disease (COVID-19) pneumonia require oxygen therapy; of these patients, approximately 5% progress to acute respiratory distress syndrome, necessitating mechanical ventilation. The incidence of secondary infections among patients with COVID-19 is relatively low (16% for bacterial infections and 6.3% for fungal infections), but is predominantly observed in those with severe respiratory failure. Microvascular damage in COVID-19 can also lead to thrombus formation, causing infarctions, and in some cases, necrotizing pneumonia with cavity formation. Pulmonary resection may be necessary in patients who develop pneumothorax or empyema. Management options in complicated COVID-19 continue to evolve and should be individualized. Here, we present a case of Aspergillus empyema with refractory pleural fistula following COVID-19 pneumonia. CASE PRESENTATION The patient was hospitalized in the intensive care unit for respiratory failure caused by COVID-19 pneumonia and developed a right pneumothorax 1 month after admission, with a halo sign in the middle lobe on computed tomography. Persistent massive air leakage and hypoxia developed, even with mechanical ventilation. Initially, to reduce the massive air leakage, endobronchial silicone spigot (endobronchial Watanabe spigot: EWS) were placed in the right B2 and middle lobe bronchi to stabilize the severe respiratory failure and septic shock. After EWS placement,…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
