A lung transplant is usually the last resort treatment for lung failure. The new lung or lungs are donated by someone who has been declared brain-dead but remains on life-support. The donor tissue must be matched as closely as possible to that of the recipient to reduce the odds that the transplanted tissue will be rejected.

While the recipient is unconscious and pain-free (general anesthesia), an incision is made in the chest. Tubes are used to re-route blood to a heart-lung bypass machine to provide oxygen and circulation during the surgery.

One or both of the patient's lungs are removed, and the donor lung or lungs are stitched (sutured) into place. Chest tubes are inserted to drain air, fluid, and blood out of the chest for several days to allow the lungs to fully re-expand.

Sometimes heart and lung transplantation are performed at the same time (heart-lung transplant), if the patient's heart is also diseased.

Indications:

Lung transplants may be recommended for patients with any severe lung disease. Some examples of disease that may require lung transplant are:

• permanent enlargement of air sacs (alveoli) with loss of ability to completely exhale (emphysema)
• hereditary lung blockages (cystic fibrosis)
• long-term (chronic) inflammation (sarcoidosis)
• permanent scarring and thickening of lung tissue (idiopathic pulmonary fibrosis)
