Living donor lobar lung transplantation: current status and future directions

Living lobar lung transplantation was developed as a procedure for adult and pediatric patients considered too ill to await cadaveric transplantation. One hundred thirty-eight living lobar transplants have been performed in 133 patients at our institution between January 1993 and September 2004. Actuarial 1-, 3-, and 5-year survival are similar to ISHLT registry data. There has been no donor mortality, and morbidity has been relatively low. Long-term postoperative pulmonary function studies demonstrate the relatively smaller-sized lobes can provide similar pulmonary function and exercise capacity to bilateral cadaveric lung transplants. Living lobar lung transplantation should be considered a viable option in patients with end-stage lung disease deemed unable to await a cadaveric organ and in those patients in which further deterioration would make cadaveric transplantation inappropriate.
