From the Guidelines
Lung transplant surgery is a complex and high-risk procedure that involves replacing a diseased lung with a healthy one from a donor.
Basics of Lung Transplant Surgery
The basics of lung transplant surgery include:
- Pre-operative preparation: Patients undergo thorough evaluation, including blood tests, imaging studies, and pulmonary function tests to assess their suitability for the procedure 1.
- Surgery: The procedure is typically performed under general anesthesia and involves making an incision in the chest to access the lungs. The diseased lung is removed, and the donor lung is implanted and connected to the airways and blood vessels.
- Immunosuppression: To prevent rejection of the transplanted lung, patients are given immunosuppressive medications, such as tacrolimus and prednisone, which are typically continued for the lifetime of the patient.
- Post-operative care: Patients are closely monitored in the intensive care unit (ICU) for several days after surgery and may require mechanical ventilation to support breathing. They are also given pain management medications and antibiotics to prevent infection.
- Follow-up care: After discharge from the hospital, patients require regular follow-up appointments with their transplant team to monitor their condition and adjust their medications as needed.
Key Considerations
Some key considerations for lung transplant surgery include:
- Type of transplant: Single lung transplantation is currently the preferred surgical operation, but bilateral lung transplantation may be a better option for some patients, particularly those with severe functional impairment 1.
- Patient selection: Patients with severe functional impairment, oxygen dependency, and a deteriorating course should be listed for lung transplantation, but relative contraindications such as unstable or inadequate psychosocial profile/stability, or significant extrapulmonary disorders, should be carefully evaluated 1.
- Survival rates: The 5-year survival rate after lung transplantation is approximately 50-60%, with graft failure, infection, and heart failure being the most common causes of early mortality, and bronchiolitis obliterans, infection, and malignancy being responsible for most late mortality 1.
It's essential to note that lung transplant surgery is a high-risk procedure, and patients should carefully discuss the potential benefits and risks with their healthcare provider before making a decision 1.
From the Research
Overview of Pulmonary Transplant Surgery
- Lung transplantation is a life-saving treatment for several end-stage lung diseases, offering improved quality of life and longer survival 2
- The optimal procedure for lung transplantation in non-septic lung conditions remains debatable, with some studies suggesting superiority of bilateral lung transplantation over single lung transplantation 3
Surgical Procedures
- The surgical procedure for lung transplantation involves several steps, including donor pneumonectomy, back bench preparation, recipient approach, pneumonectomy, and anastomoses of the bronchial, pulmonary artery, and pulmonary venous vessels 4
- A standardized technique is considered important for the success of a lung transplant program, with minimal variations over the years 5
Types of Lung Transplantation
- Single and bilateral lung transplantation are two types of procedures, with the choice of procedure often individualized based on the patient's condition and the availability of organs 3
- Bilateral lung transplantation has been favored by many lung transplantation centers for certain conditions, such as pulmonary fibrosis and COPD, due to suggested superiority in long-term survival 3
Post-Transplant Complications
- Lung transplantation recipients are at risk of numerous post-transplant complications, including surgical complications, primary graft dysfunction, acute rejection, opportunistic infection, and chronic lung allograft dysfunction (CLAD) 6
- Advances in pre- and post-transplant management have led to improved outcomes, including sound guidelines for candidate selection, improved surgical techniques, and effective therapies for treating infectious complications 6
