Lung transplant
Definition:
Lung transplant is surgery to replace one or both diseased lungs with healthy lungs from a human donor.

Alternative Names:
Lung graft; Lung transplantation

Description:

A lung transplant is 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: Lung transplant is not recommended for patients with serious illnesses, such as reduced kidney or liver function, or other serious diseases.
Risks:
Risks for any anesthesia are:Risks for any surgery are:Additional risks of transplant includes:
Expectations after surgery:
Lung transplant is an extreme measure for patients with life-threatening lung disease or damage. Current survival rates are as high as 80% at 1 year following transplantation and 60% at 4 years.

Fighting rejection is an ongoing process. The body's immune system considers the transplanted organ as an invader (much like an infection) and may attack it. To prevent rejection, organ transplant patients must take anti-rejection (immunosuppression) drugs (such as cyclosporine and corticosteroids) that suppress the body's immune response and reduce the chance of rejection. As a result, however, these drugs also reduce the body's natural ability to fight off various infections.
Convalescence:
An extended hospital stay should be expected. The recovery period is about 6 months. Frequent check-ups with blood tests and X-ray tests will be necessary for years.
