    Abstract:
    This article presents the case of a 62-year-old patient with cancer in the left upper pulmonary lobe who underwent lobe resection with postoperative respiratory insufficiency. The right upper lobe had already been resected 5 years earlier because of an adenocarcinoma. Prior to the present surgery a computed tomography scan detected a narrow stenosis at the former resection site; however, both pulmonary lobes beyond this stenosis appeared to be sufficiently ventilated. After resection of the left upper lobe attempted extubation was unsuccessful due to insufficient global gas exchange as the stenosis prevented ventilation of the right lung. Bronchoscopy provided evidence of a normal diameter of the bronchus behind the stenosis so both lobes were to be recruited after possible correction of this section. A veno-venous extracorporeal membrane oxygenation device (ECMO) was established as bridging therapy to attain normal gas exchange. As the patient showed no muscle weakness and was cooperative, extubation was performed and spontaneous breathing occurred without any support while still under ECMO treatment. The stenosis was reduced by bronchoscopic laser resection within seven consecutive sessions. Each of these surgeries was conducted with the patient under general anesthesia with oral intubation and jet ventilation in combination with the ECMO. The patient was extubated after each treatment session and weaned from ECMO after the final resection within 2 days. This case demonstrates the use of ECMO in combination with surgical procedures in a spontaneously breathing patient as a causal therapy and option for selected patients to prevent complications from long-term ventilation.
