Our Summary
This research paper evaluates a procedure called ex vivo lung perfusion (EVLP), which is a method used to prepare lungs for transplantation. The study looked at whether this procedure is performed better at the transplant center itself, or at separate specialized centers (EPCs). The research was conducted using data from the United Network for Organ Sharing Database.
The study found that the use of EPCs was more common in the Southern United States. After comparing the data, the researchers found no significant difference in outcomes between the two groups. This includes complications like stroke, dialysis, problems with the airway, the use of ECMO (a life support machine), usage of a ventilator, or severe issues with the transplanted lung.
The study also looked at 3-year survival rates and found them to be very similar, 68.9% for those treated at the transplant program and 67.6% for the EPC group. Even with more challenging cases (where the lungs had been without blood supply for 14+ hours), there was no significant difference in survival rates, though the patients treated at the transplant center had longer hospital stays.
In conclusion, the research suggests that EVLP can be performed at specialized external centers with similar results to those performed at the transplant center. This means that lung transplant programs that don’t have the resources to perform EVLP could potentially use these external centers.

Doctor’s Tip
A helpful tip a doctor might tell a patient about lung transplant is to follow a strict medication regimen post-transplant to prevent rejection and infection. It is important to attend all follow-up appointments and communicate any changes in symptoms to your healthcare team immediately. Additionally, maintaining a healthy lifestyle with regular exercise and a balanced diet can help support the success of the transplant.
Suitable For
Patients who are typically recommended for lung transplant are those with end-stage lung disease, such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis, cystic fibrosis, and pulmonary hypertension. These patients have severe symptoms that significantly impact their quality of life and have failed to improve with other treatments.
In addition, patients who have a poor prognosis and are not expected to survive more than a year without a transplant may also be recommended for lung transplant. This includes patients who are on supplemental oxygen, have frequent exacerbations, or have severe limitations in their daily activities.
It is important for patients to undergo a thorough evaluation by a multidisciplinary team, including pulmonologists, surgeons, social workers, and psychologists, to determine if they are suitable candidates for lung transplant. Factors such as age, overall health, willingness to adhere to post-transplant care, and support system are also taken into consideration when recommending a patient for lung transplant.
Timeline
Before a lung transplant, a patient typically undergoes a series of evaluations and tests to determine if they are a suitable candidate for the procedure. This includes medical history reviews, physical exams, blood tests, imaging studies, pulmonary function tests, and possibly a psychological evaluation. Once deemed eligible, the patient is placed on the transplant waiting list and must wait for a suitable donor organ to become available.
After receiving a lung transplant, the patient will be closely monitored in the hospital for several weeks to ensure the new organ is functioning properly and to watch for any signs of rejection or complications. They will need to take immunosuppressant medications for the rest of their life to prevent rejection of the new lung. Physical therapy and rehabilitation will also be required to help the patient regain strength and lung function.
Overall, the goal of a lung transplant is to improve the patient’s quality of life and extend their lifespan. With proper care and management, many patients are able to return to a relatively normal lifestyle following a successful lung transplant.
