Living-donor, single-lobe lung transplantation and simultaneous contralateral pneumonectomy in a child.

An 8-year-old girl became ventilator-dependent due to severe bronchiolitis obliterans/interstitial pneumonia caused by cord-blood cell transplantation for neuroblastoma. Her mother's right lower lobe was twice as large as her right chest cavity. She successfully underwent living-donor, right, single-lobe lung transplantation and simultaneous left pneumonectomy under conditions of cardiopulmonary bypass. At 18 months after transplantation, the patient returned to school life and is currently able to carry out daily activities without supplemental oxygen.
