Living-donor lobar lung transplantation (LDLLT) is indicated for rapidly deteriorating patients, and the total volume of two lower lobe grafts must be sufficient for the recipient. To rescue patients with small lobar grafts, we performed five LDLLTs sparing native upper lobes. This strategy was used when upper lobes or segments were preoperatively less impaired. There were no hospital deaths. Extracorporeal circulation time and operative time were similar to those of conventional LDLLTs. The length of intensive care unit stay was also similar. Late complications attributed to the spared lungs were airway infection in one recipient and pneumothorax in two but they were successfully managed. All recipients were discharged without supplemental oxygen. The spared lung volumes measured by volumetry did not change after LDLLT. Lung perfusion scintigraphy performed at 1 year showed remaining perfusion in the spared lungs, although much less than in the grafts. These results suggested that the spared lobes kept adequate space in the thoracic cavity and kept functioning to a limited extent. The new lobar-sparing strategy appears feasible and effective in LDLLT using small grafts for selected patients when the upper lobes or segments are less impaired.
