Benefits of Lung Transplants
Lung transplants have been shown to improve quality of life and the ability to perform physical activities related to muscle strength. While they do not, as of yet, increase long-term survival in COPD, short-term survival continues to improve. In fact, in a 2005 survey of patients who had single-lung transplants, the National Heart, Lung and Blood Institute reports that:
- More than 82% of patients survive the first year after a transplant
- Approximately 60% survive 3 years after a transplant
- More than 43% survive 5 years after a transplant
As surgical procedures and technology improve, perhaps one day, long-term survival will be possible.
Who Qualifies for a Lung Transplant?
To be referred by your doctor for a possible lung transplant, you should meet the following criteria:
- be less than 65 years of age (although some programs will consider older patients)
- have an FEV1 of less than 20% predicted (although some programs accept an FEV1 that is higher, depending upon the circumstances)
- have chronic hypercapnia and a lowered Pa02 as measured by arterial blood gases
- have secondary pulmonary hypertension
- have a BODE Index score of > 7
- your chances for survival should be greater if you have a lung transplant, than if you don't
What if I've Had Previous Lung Surgery?Having had previous lung surgery such as lung volume reduction surgery (LVRS) or bullectomy does not disqualify you from having a lung transplant. In some patients, prior lung surgery can actually work in their favor.
Complications of Lung Transplant
Apart from the possibility of death during the operation, complications of lung transplants include:
- rejection of the transplanted lung
- bronchiolitis obliterans
- lymphoproliferative disease
Risk Factors for Complications After Lung Transplant
There are many factors that may contribute to a poor outcome in lung transplant surgeries, including smoking, poor baseline health, increased age, obesity and the severity of your disease. Your doctor will review these risk factors with you very carefully, to make sure that the benefits of the surgery outweigh the risks.
