A major problem in clinical lung transplantation is the shortage of donor lungs. Only about 20% of donor lungs are accepted
for transplantation. We have recently reported the results of the first six double lung transplantations performed with donor
that had been deemed unsuitable for transplantation by the Scandiatransplant, Eurotransplant, and
UK Transplant organizations because the arterial oxygen pressure was less than 40 kPa. The three-month survival of patients
undergoing transplant with these lungs was 100%. One patient died due to sepsis after 95 days, and one due to rejection after 9
months. Four recipients are still alive and well 24 months after transplantation, with no signs of bronchiolitis obliterans syndrome.
The donor lungs were reconditioned
in an extracorporeal membrane oxygenation circuit using STEEN Solution
mixed with erythrocytes, to dehydrate edematous lung tissue. Functional evaluation was performed with deoxygenated perfusate
at different inspired fractions of oxygen. The arterial oxygen pressure was significantly improved in this model.
evaluation model is thus a valuable addition to the armamentarium in increasing the number of acceptable lungs
in a donor population with inferior arterial oxygen pressure values, thereby increasing the lung donor pool for transplantation.
evaluation model has also shown to be of great value in evaluate donor lungs from donor lungs from uncontrolled
none-heart beating donors also called donation after cardiac death Maastricht classification II.
