Infected pulmonary aneurysm following pulmonary artery banding

A 1-month-old girl, diagnosed with a common atrioventricular canal, moderate atrioventricular valvular regurgitation, and pulmonary hypertension, underwent pulmonary artery banding. Postoperatively, methicillin-resistant Staphylococcus aureus wound infection was treated with antibiotics. One month later, emergency surgery was performed for oozing rupture of an infected pulmonary aneurysm. The pulmonary aneurysm was completely resected, the banding tape was removed, and pulmonary angioplasty was performed to create pulmonary stenosis without using foreign material. Methicillin-resistant Staphylococcus aureus was cultured from the resected tissues and banding tape. The patient was discharged after antibiotic administration. Correction was performed at 1 year of age, and she remains well.
