Successful thoracoscopic treatment of severe bilateral empyema in an infant.

We report a case of rapid progression of bilateral pyothorax exacerbated by viral influenza in an infant. The patient, an 11-month-old girl, was diagnosed with viral influenza, and oseltamivir phosphate was administered. However, after only 4 days the influenza was followed by rapid progression of methicillin-susceptible Staphylococcus aureus (MSSA) pneumonia and pyothorax, resulting in disseminated intravascular coagulation. Because thoracentesis and antibiotics could not control the pyothorax, a serious condition, we performed bilateral video-assisted thoracoscopic decortication on the eighth hospital day. She recovered with excellent lung expansion and was discharged on the 37th hospital day.
