Abstract

Candidates for pulmonary transplantation have been limited because of extreme susceptibility to lung infections and pulmonary edema in the brain-dead donor. To ameliorate the donor shortage, two possibilities for expanding the donor source have been presented. i.e. xenotransplantation and transplantation from cardiac-dead donors. The present study was conducted to evaluate the possibility of lung transplantation from a non-heart-beating donor following brain death, using a canine model. Six mongrel dogs were put into a state of brain death by elevating intracranial pressure with a balloon catheter. Following the intravenous administration of methylprednisolone and heparin used for 6-hour management following brain death mechanical ventilation was discontinued leading to cardiac arrest with in a few minutes. Excision of the left lung was scheduled for twenty minutes after cardiac arrest, followed by washing out the pulmonary vasculature with cold Ep4 solution, and orthotopic transplantation into the recipient animal. Immunosuppresion was achieved with methylprednisolone and azathioprine. A right pulmonary arterial occlusion test (RPAO) was performed to assess graft function immediately and 7 days postoperatively. All but one animal survived and three animals had an uneventful postoperative course, with the transplants alone according to immediate and 7 day postoperative, respectively, RPAO results. These outcomes indicate the possible feasability of lung transplantation from non-heart-beating donors following brain death.
