Severe scoliosis with an impaired pulmonary allograft function after pediatric unilateral lung transplantation

Left‐unilateral single‐lobe lung transplantation from a living donor was performed in a 4-year-old boy who suffered from severe respiratory failure caused by bronchiolitis obliterans (BO) as a result of graft versus host disease (GVHD) after peripheral blood stem cell transplantation (PBSCT). The patient grew well during his early childhood years, with an excellent lung allograft function. However, severe thoracic scoliosis occurred 7 years after lung transplantation, which ultimately resulted in compression of the lung allograft followed by severe respiratory dysfunction, and the patient became dependent on mechanical ventilation support. Posterior spinal fusion of Th2‐L3 with instrumentation and bone grafting was performed to correct scoliosis in the hope of recovering his thoracic capacity. The left thoracic volume was dramatically improved immediately after spinal fusion surgery, and the patient was ultimately weaned off of mechanical ventilation after a year of pulmonary rehabilitation.
