title: Outcomes from paired single-lung transplants from the same donor.
abstract: METHODS
  Simultaneous, paired single-lung transplants from a single organ donor is one way to maximize lung transplant opportunities. Paired transplants allow comparison between left and right single-lung transplants and also provide insight into the relevance of donor vs recipient factors in rejection outcomes.
  
  
  RESULTS
  Of 76 paired transplants (38 pairs) performed at the Alfred Hospital, 68 patients have survived >30 days. We observed no significant differences between left and right single-lung transplants in ICU stay (median, 3.1 vs 3.0 days; range, 0.5 to 83 vs 0.5 to 76 days), hospital stay (median, 19.5 vs 24.0 days; range, 1 to 118 vs 11 to 144 days), airway complications (5 vs 3), and 5-year survival (60% vs 50%). The 6 month, and 1- and 2-year survivals were lower in left single-lung transplant recipients, primarily related to increased mortality from airway complications. In 28 pairs, both recipients survived 90 days, and the incidence, frequency, and time of onset of acute rejection and chronic rejection (bronchiolitis obliterans syndrome [BOS]) were not significantly different. When sequentially performed lung transplants were separately analyzed, the incidence of acute rejection was not related to graft ischemic time.
  
  
  CONCLUSIONS
  The general outcomes of right and left transplants are similar, although we observed increased 6-month to 2-year mortality associated with left lung transplantation. The lack of correlation between the incidence of acute rejection episodes or the severity of BOS in paired allograft recipients suggests that "donor factors" are not the dominant cause.
