Bronchiolitis obliterans syndrome after allogeneic haematopoietic stem cell transplantation has aroused clinical concern. We describe a case of a 39-year-old female patient diagnosed as bronchiolitis obliterans syndrome and concomitant pectus excavatum with a Haller index of 3.32. The patient received bilateral lung transplantation and simultaneously underwent Nuss surgery via bilateral anterolateral thoracotomies with veno-arterial extracorporeal membrane oxygenation support. The bar was removed 2 years after transplantation, and the patient has been stable in the past 4 years with haematological remission and satisfactory lung function.
