Single lung transplantation (SLT) has become a therapeutic option for the treatment of end-stage obstructive lung disease. Between January 1989 and June 1990, there were 14 patients with end-stage obstructive lung disease who underwent SLT. Eleven of these patients were surviving at 1 year following transplantation. Three of the patients had received left-sided SLT, and eight had received right-sided SLT. In the patients receiving left-sided SLT, the native right lung radiographically appeared to compress the left lung graft. In the patients receiving right-sided SLT, the native left lung did not appear to compress the right lung graft. We hypothesized that right SLT may provide a functional advantage over left SLT for patients with obstructive lung disease. We compared pulmonary function test results before and after transplantation (approximately 3 and 12 months) and compared quantitative ventilation-perfusion lung scan results between the patients with left SLT and those with right SLT. Additionally, we compared graded-exercise test results at 3 and 12 months after transplant between the two groups. Our data revealed no statistical difference in pulmonary function test results or graded-exercise test results between the two groups, although patients undergoing right SLT showed greater increases in FEV1 and forced vital capacity than those undergoing left SLT. Quantitative ventilation and perfusion were greater to the graft in patients receiving right-sided SLT than in patients receiving left-sided SLT, most likely due to the larger size of the right lung. We conclude that there is no functional difference between patients undergoing left or right SLT for end-stage obstructive lung disease.
