Extracorporeal membrane oxygenation bridging for chemotherapy in obstructing mediastinal mass after cardiopulmonary arrest

Abstract

Abstract Background In a sedated patient, airway compression by a large mediastinal mass can cause acute fatal cardiopulmonary arrest. Extracorporeal membrane oxygenation (ECMO) has been investigated to protect the airway and provided cardiopulmonary stability. The use of ECMO in the management of mediastinal masses was reported, however, the management complicated by cardiopulmonary arrest is poorly documented. Case presentation 32-year-old female presented with acute onset of left arm swelling and subacute onset of dry cough. Further investigation showed a deep venous thrombosis in left upper extremity as well as a large mediastinal mass. She underwent mediastinoscopy with biopsy of the mass which was complicated by cardiopulmonary arrest secondary to airway obstruction by the mediastinal mass. Venoarterial ECMO was initiated, while concurrently treating with a chemotherapy. The mediastinal mass responded to the chemotherapy and reduced in size during 2 days of ECMO support. She was extubated successfully and decannulated after 2 days of ECMO and discharged later. Conclusions Extracorporeal membrane oxygenation can serve as a viable strategy to facilitate cardiopulmonary support while concurrently treating the tumor with chemotherapy, ultimately allowing for the recovery of cardiopulmonary function, and achieving satisfactory outcomes.
