Native lung-sparing lobar transplantation for pulmonary emphysema

The living-donor lobar lung transplantation procedure has been developed clinically as an alternative approach for patients considered too ill to await cadaveric transplantation. With this procedure, 2 lobes are implanted in the recipient in place of whole right and left lungs, respectively. However, the shortage of graft volume can be a problem when compared with full-sized cadaveric grafts. In an attempt to solve this problem, we have developed a native lobe-preserving lobar transplant technique using a large animal model. We report a first successful case of a patient undergoing native lobe-preserving lobar lung transplantation for severe pulmonary emphysema.
