  • Pectus Excavatum Repair During Lung Transplantation in a 5-Year-Old: A Case Report. Interdisciplinary cardiovascular and thoracic surgery Schwab, M. E., Martin, E., Si, X., Chao, S. D. 2025; 40 (11)

    Abstract

    Chest wall deformities are considered a risk factor for lung transplantation. A 5-year-old girl with protein surfactant C deficiency, interstitial lung disease, pulmonary hypertension, and pectus excavatum (Haller 5.9) underwent lung transplantation and Nuss bar placement. Correction of her pectus was necessary to accommodate donor lungs. She was discharged after 18 days. We hope this youngest described child who underwent simultaneous transplant and pectus correction with excellent outcomes will lead others to consider concomitant surgeries.
