ABSTRACT: To investigate the selection of recipients, operative technique, and perioperative management of lung transplantation for silicosis. Lung transplantations (LTx) were performed for five end-stage silicosis in our hospital who were diagnosed in accordance with recommendations of the local Prophylactic Therapeutic Institution for Occupational Diseases. The chest roentgenogram and high resolution CT showed somewhat pulmonary interstitial fibrosis, pulmonary emphysema and massive opacities. The mean pulmonary artery pressure (mPAP) was > 30mmHg, NYHA III or IV. Two patients received thoracic surgery prior to LTx, one patient was ventilator-dependent. One patient received bilateral sequence lung transplantation (BSLT) under extracorporeal membrane oxygenation (ECMO) support. Four patients received single lung transplantation (SLT), 3 under ECMO support. Patient five died of multiple organ failure on postoperative day 8, the remaining four patients were discharged from hospital. During follow up, patient three died of severe infection 7 month postoperatively, the remaining three patients were alive for 5 years, 3 years and 2 years respectively, and lived good quality of life, especially with lower mPAP and improved lung function. Although our patients suffered low-grade chronic rejection with the manifestation of bronchiolitis obliterative syndrome (BOS). Lung transplantation is a viable option for patients with end-stage silicosis, providing acceptable quality of life and survival. Both SLT and BSLT are satisfactory approach for end-stage silicosis,and long-term survival requires further investigations.Zhonghua lao dong wei sheng zhi ye bing za zhi = Zhonghua laodong weisheng zhiyebing zazhi = Chinese journal of industrial hygiene and occupational diseases 07/2011; 29(7):502-5.
