Questions About Lung Transplantation


Why is Lung Transplantation Performed?

Lung transplantation is a complex medical procedure that involves the removal of a damaged or diseased lung and replacing it with a healthy lung from a donor. It is often performed as a last resort for patients with end-stage lung disease who have exhausted all other treatment options. In this article, we will discuss why lung transplantation is performed, how it is performed, what happens after the surgery, and the risks involved in the procedure.

Reasons for Lung Transplantation

There are several reasons why a patient may require a lung transplantation, some of which include:

End-Stage Lung Disease

Lung transplantation is often performed for patients with end-stage lung disease, which refers to severe and irreversible lung damage or dysfunction that cannot be treated with conventional therapy. Common end-stage lung diseases include chronic obstructive pulmonary disease (COPD), cystic fibrosis, pulmonary fibrosis, and pulmonary hypertension.

Lung Cancer

In some cases, lung transplantation may be recommended for patients with early-stage lung cancer that cannot be treated with other methods such as surgery, radiation therapy, or chemotherapy.

Congenital Lung Defects

Lung transplantation may be performed for patients with congenital lung defects, such as pulmonary hypoplasia or bronchopulmonary dysplasia, which can lead to severe respiratory problems.

How is Lung Transplantation Performed?

Lung transplantation is a major surgical procedure that requires careful preparation, coordination, and a team of highly skilled medical professionals. The procedure typically involves the following steps:

Donor Lung Procurement

The first step in the lung transplantation process is to identify a suitable donor lung. This may involve a search for a suitable donor on a national or international donor registry, or a family member or friend of the patient may donate the lung.

Preoperative Preparation

Before the surgery, the patient will undergo several tests and evaluations to ensure that they are healthy enough to undergo the procedure. This may include blood tests, imaging tests, pulmonary function tests, and psychological evaluations.

Anesthesia and Incision

Once the patient is prepared for surgery, they will be given general anesthesia to ensure that they are unconscious and do not feel any pain during the procedure. The surgeon will then make an incision in the chest to gain access to the lungs.

Donor Lung Implantation

The surgeon will then carefully remove the damaged or diseased lung and replace it with the healthy donor lung. The new lung is connected to the patient’s airways, blood vessels, and nerves, and the incision is closed.

What Happens After Lung Transplantation?

After the surgery, the patient will be closely monitored in the intensive care unit (ICU) for several days to ensure that they are stable and recovering well. They will be given medications to prevent rejection of the new lung and to manage any pain or discomfort.

Recovery and Rehabilitation

Once the patient is stable enough to leave the ICU, they will be transferred to a regular hospital room for further recovery and rehabilitation. They will undergo physical therapy, breathing exercises, and other therapies to help them regain their strength and mobility.

Long-Term Care

After being discharged from the hospital, the patient will require ongoing monitoring and care to ensure that the new lung is functioning properly and to prevent complications. They will need to take medications to prevent rejection of the new lung for the rest of their life and undergo regular follow-up appointments with their medical team.

What are the Risks of Lung Transplantation?

Like any major surgery, lung transplantation carries several risks and potential complications, some of which include:


The most significant risk of lung transplantation is rejection of the new lung by the patient’s immune system. This occurs when the immune system recognizes the new lung as foreign and attacks it, leading to lung failure. To prevent rejection, the patient will need to take immunosuppressive medications for the rest of their life, which can increase their risk of infections and other health problems.


Because the patient’s immune system is suppressed to prevent rejection, they may be more susceptible to infections. This can be especially dangerous in the first few months after the surgery, when the patient’s immune system is most vulnerable.

Complications from Surgery

Lung transplantation is a complex surgery that can involve several potential complications, including bleeding, infection, and damage to surrounding organs and tissues.

Other Risks

Other risks of lung transplantation may include complications related to anesthesia, side effects from medications, and the development of new health problems, such as diabetes or kidney disease.

Overall, lung transplantation is a major medical procedure that is often performed as a last resort for patients with end-stage lung disease. While it can be life-saving, it carries significant risks and requires ongoing care and monitoring to ensure the patient’s health and wellbeing. If you or a loved one is considering lung transplantation, it is important to discuss the risks and benefits with your medical team and make an informed decision based on your individual needs and circumstances.


  1. How long does the lung transplantation surgery take?

The surgery typically takes several hours to complete, depending on the complexity of the case and any potential complications.

  1. How long does it take to recover from lung transplantation?

Recovery can vary depending on the individual patient and their specific case, but it typically takes several weeks to several months to fully recover from the surgery.

  1. Can the body reject a lung transplant?

Yes, rejection is a significant risk of lung transplantation. Patients will need to take immunosuppressive medications for the rest of their life to prevent rejection.

  1. How long can a transplanted lung last?

The lifespan of a transplanted lung can vary, but on average, a lung transplant can last for 5 to 10 years or more.

  1. What are some alternatives to lung transplantation?

Alternative treatments for end-stage lung disease may include oxygen therapy, pulmonary rehabilitation, and medications to manage symptoms. In some cases, lung volume reduction surgery may also be an option.
