Lung transplant

In 1990, the first transplant operation of a lung from a live donor to a recipient is performed by Dr. Vaughn A. Starnes, Stanford University Medical Center, Stanford, California. A mother was the living donor to her 12-year-old daughter. Dr Starnes is a world-renowned pediatric cardiothoracic surgeons who has performed several transplantation "firsts," including transplanting a heart and lung into a four-month old baby - the youngest ever. Lung transplantation was first attempted in 1963, and heart-lung transplantation in 1968. The first successful heart-lung transplant, by Dr. Bruce Reitz, was at Stanford in 1981. The world's first successful lung transplants were at Toronto General Hospital, Ont. (Single lung, 1983; double,1986).
