Infected pulmonary aneurysm following pulmonary artery banding

Area of Science:

• Pediatric Cardiology
• Infectious Diseases
• Surgical Innovation

Background:

• A 1-month-old infant presented with a common atrioventricular canal, moderate atrioventricular valvular regurgitation, and pulmonary hypertension.
• Pulmonary artery banding was performed to manage pulmonary hypertension.

Observation:

• Postoperatively, the patient developed a methicillin-resistant Staphylococcus aureus (MRSA) wound infection, treated with antibiotics.
• One month later, an infected pulmonary aneurysm ruptured, necessitating emergency surgery.

Findings:

• The infected pulmonary aneurysm was resected, and the pulmonary artery banding tape was removed.
• Pulmonary angioplasty was performed to create pulmonary stenosis without foreign materials, with MRSA cultured from resected tissues and banding tape.
• The patient recovered after antibiotic treatment and underwent successful corrective surgery at 1 year of age.

Implications:

• This case highlights the potential complications of pulmonary artery banding, including infectious aneurysms.
• It demonstrates the successful management of a complex MRSA infection and surgical complication using material removal and angioplasty.
• The findings suggest that avoiding foreign material during revision procedures may be beneficial in managing such infections.
