First successful combination of extracorporeal membrane oxygenation (ECMO) with video-assisted thoracic surgery (VATS) of pulmonary bullae resection in the management of refractory pneumothorax in a critically ill patient with H7N9 pneumonia and acute respiratory distress syndrome: A case report.

Abstract

Rationale:At present, data regarding refractory pneumothorax treated with video-assisted thoracic surgery (VATS) in combination with extracorporeal membrane oxygenation (ECMO) in critically ill patients with H7N9 pneumonia have never been reported.Patient concerns:A laboratory-confirmed case of human infection with avian influenza A (H7N9) virus was treated in our hospital. Acute respiratory distress syndrome (ARDS) developed and the patient was oxygenated via veno-venous ECMO due to the failure of mechanical ventilation. Unfortunately, a right refractory pneumothorax occurred. Despite treatment with pleural drainage and select bronchial occlusion, the patient still failed to improve.Diagnosis:Fatal H7N9 pneumonia complicated with severe ARDS, pulmonary bullae, and refractory pneumothorax.Interventions:Successful combination of ECMO with VATS of pulmonary bullae resection was performed and pneumothorax was cured.Outcomes:One week after the operation, ECMO was removed. However, the patient finally developed multiorgan failure (MOF) complicated by refractory hypoxemia due to progressive lung fibrosis and died 36 days after admission.Lessons:Although the patient died of MOF triggered by severe lung fibrosis at last, the successful treatment of refractory pneumothorax by combination of ECMO with VATS is encouraging. Thus, when refractory pneumothorax in a patient with severe pulmonary dysfunction fails to improve through routine therapy, the treatment of pneumothorax by VATS based on ECMO support can be considered as a feasible selection.
