Surgery Overview
Lung transplant is an option for a few people who have severe lung
problems that are caused by
cystic fibrosis. The procedure removes the diseased
lungs and replaces them with healthy lungs from a recently deceased
donor.
Sometimes a procedure called a living-donor lobar lung transplant
is performed while a person is waiting for a full lung transplant. In this
procedure, the lower section (lobe) of one lung in each of two living donors
(who may be related or unrelated to the person who has cystic fibrosis) is
transplanted into the person who has cystic fibrosis. Because this complicated
transplant involves two living donors, it is performed less often than other
kinds of lung transplants.
What To Expect After Surgery
After lung transplant surgery, you will be put on a mechanical
ventilator, which is a machine that temporarily takes over the breathing
process. If there are no complications, you will use the ventilator for 1 to 2
days.
Generally, you will need to stay in the hospital for 2 to 3 weeks
after the transplant.
Why It Is Done
Some people who have severe lung damage that was caused by cystic
fibrosis may get a lung transplant. Experts aren't sure if a lung transplant
helps a child with cystic fibrosis live longer.1
People who have mild or moderate disease do not usually get a transplant
because the risks are greater than the benefits.
Several tests can help determine how well a lung transplant or a
living-donor lobar lung transplant might work. These tests include
lung function tests,
arterial blood gas tests, and exercise
capacity.
In order to be accepted for lung transplant, you must have an
evaluation to find out how severe your lung disease is, whether you have any
other diseases, and whether you are able to follow a complex pretransplant and
follow-up regimen.
A person who is age 12 and older is
assigned priority for transplant based on a Lung Allocation Score. The Lung
Allocation Score uses the following measures:
- Waitlist urgency: the expected number of days
lived without a transplant during an additional year on the
waitlist
- Post-transplant survival: the expected number of days
lived during the first year after getting a transplant
- Transplant
benefit: the post-transplant survival measure minus the waitlist urgency
measure.
A child who is age 0 to 11 is assigned
priority for a transplant based upon how long they have been waiting.
In addition to the criteria above, all lung transplant recipients
are chosen based on
blood type, tissue type, size of the organ, medical
urgency, time already spent on the waiting list, and the distance between the
donor and the recipient. More information can be found on the United Network
for Organ Sharing (UNOS) Web site: www.unos.org.
How Well It Works
- About 70 out of 100 people who receive a lung
transplant survive at least 1 year after the procedure. And about 48 out of 100
survive at least 5 years.2
- People with cystic fibrosis have the same survival rate after a
lung transplant as people who have lung transplants for other health
problems.
- Lung transplant is used only for people who have very
severe cystic fibrosis. For people who have mild or moderate cystic fibrosis,
the risks of the procedure are greater than the benefits.
Risks
The main risks of lung transplant are problems during the surgery
and rejection of the donated organs. Infection and rejection of transplanted
organs have similar symptoms, including fever, tiredness, and difficulty
breathing.
After a lung transplant, preventive
antibiotic therapy starts right away.
Immunosuppressant medicines are also given, usually for the rest of your life.
Although immunosuppressant medicines raise the chances that your body will
accept the new lungs, they also make it harder for your body to fight off
infection.
What To Think About
- Lung transplant surgery does not prevent or
improve any problems that cystic fibrosis may be causing in other parts of your
body.
- Lung transplant surgery is generally recommended only for
people who have severe lung damage because the risks can be greater than the
benefits
- If you are a candidate for a lung transplant, you may have
to wait 6 months to 4 years. The United Network for Organ Sharing (UNOS)
regularly updates its guidelines for transplant selection. For more
information, go to

- Having a lung transplant is still a limited option in the United
States and is usually available only in certain major medical centers. You may
have to travel or move to another city to have the operation.
