AbstractUnilateral lung transplantation has become a successful method for the treatment of end-stage pulmonary disease, whereas double-lung transplantation has provided benefit to patients with nonfibrotic lung disease such as emphysema and cystic fibrosis. In the past 5 years, 16 single-lung and 13 double-lung transplantations have been performed by the Toronto Lung Transplant Group in patients with end-stage lung disease. Seven perioperative and two late deaths have been recorded so far. Since the introduction of heart-lung transplantation at Stanford in 1981 and at Pittsburgh in 1982 for the treatment of Eisenmenger's syndrome and terminal pulmonary vascular disease, more than 350 combined heart-lung transplantations have been carried out throughout the world. Presently, the 2-year actuarial survival is about 62%. The long-term results have not yet reached the same level of success as those of cardiac transplantation alone. Although several factors have played a role in this difference, a prominent cause has been the lack of a reliable and simple method for pulmonary protection against prolonged ischemia. Most of the techniques proposed against ischemia can be classified as normothermic or static hypothermic cardiopulmonary preservation. The use of the normothermic method has not always been successful. For this reason, interest has now been directed toward the potential for hypothermic preservation of the heart-lung bloc and the use of free-radical scavenger therapy in the reduction of reperfusion injury.
