[Unilateral lung transplant in a case of terminal pulmonary fibrosis].
Up to 1980, less than 40 lung transplants had been reported worldwide without any success. The factors influencing these poor results were related to complications at the bronchial anastomosis and ineffective immunosuppressive regimens. The development of new immunosuppressive drugs has permitted the reevaluation of lung transplantation as a therapeutic option. The success with heart-lung transplantation stimulated the development of clinical human single-lung and double-lung transplantation. However the world experience is still scarce. In our institution we have developed experimental work leading to the establishment of a lung transplant program. This paper describes our first single lung transplant patient. The patient, a 33 year old man with end-stage pulmonary fibrosis, was totally oxygen dependant, maintaining arterial blood oxygen levels below 40 mmHg without oxygen supplementation and confined to a wheelchair. A single left lung transplant was performed from a young brain-dead donor. The bronchial anastomosis was protected with an omental flap. The immunosuppressive regimen was based on cyclosporin A and azathioprine from the beginning, adding prednisone on the third postoperative week. There has been only one episode suggestive of acute rejection which was managed with methylprednisolone. On the 9th postoperative week the patient developed a bronchial stenoses at the anastomotic site which required dilation and stenting with an endobronchial silastic stent. His clinical course has been uneventful since then. His ventilatory parameters showed an increase of vital capacity from 900 to 2100 mL and his FEV1 from 700 to 1500 mL. His gas exchange has been normal with arterial blood gas oxygen above 60 mmHg and oxygen saturation above 94%.(ABSTRACT TRUNCATED AT 250 WORDS)
