Extracorporeal membrane oxygenation and toilet bronchoscopy as a bridge to pneumonectomy in severe community-acquired methicillin-resistant Staphylococcus aureus pneumonia.

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) pneumonia is associated with very high mortality. Though surgical evacuation of necrotic tissue is desirable in patients unresponsive to antimicrobial therapy, most patients are acutely ill precluding surgical intervention. We utilized a combination of extracorporeal membrane oxygenation (ECMO) with frequent toilet bronchoscopies to salvage an unaffected right lung from spillage of necrotic pus from left lung cavitary CA-MRSA pneumonia in a 22-year-old patient. Our patient while on ECMO and after decannulation was positioned with the right lung up at all times with 1-2 toilet bronchoscopies every day for almost 30 days. This time was utilized for ventilator weaning and optimizing the nutritional status prior to extrapleural left pneumonectomy. Prevention of soilage of the unaffected right lung and mitigating volutrauma with ECMO support combined with the subsequent surgical evacuation of necrotic left lung tissue led to a favorable outcome in this case. This strategy could be of value in similar presentations of unilateral suppurative pneumonia, where the progressive disease occurs despite optimal medical therapy.
