Lung Transplant
A lung transplant is a surgical procedure in which one or both diseased lungs are replaced with healthy lungs from a deceased donor. It is considered when a patient has end-stage lung disease and no other treatment options offer relief or survival.
Who Needs a Lung Transplant?
Lung transplants are reserved for patients with severe, irreversible lung conditions, including:
- Idiopathic Pulmonary Fibrosis (IPF)
- Chronic Obstructive Pulmonary Disease (COPD)
- Cystic Fibrosis
- Pulmonary Hypertension
- Bronchiectasis
- Sarcoidosis
- Post-tubercular destroyed lungs (in some cases)
Patients are considered only when all other treatments have failed and their life expectancy is significantly reduced.
Types of Lung Transplants
- Single Lung Transplant Only one lung is replaced. Often done for diseases that affect one side or progress slowly.
- Double Lung Transplant Both lungs are replaced. Preferred in conditions like cystic fibrosis or severe COPD.
- Heart-Lung Transplant Performed when both the heart and lungs are failing, though this is rare.
Eligibility Criteria
To qualify for a lung transplant, a patient must:
- Have advanced lung disease that limits quality of life
- Be free from active infections or cancer
- Have strong heart, liver, and kidney function
- Be physically fit for surgery and rehabilitation
- Commit to lifelong medication and follow-up care
- Have strong social and psychological support
Pre-Transplant Evaluation
A thorough evaluation includes:
- Blood tests
- Imaging (CT scan, X-ray)
- Pulmonary function tests (PFTs)
- Cardiac evaluation
- Psychosocial assessment
- Nutritional and physical therapy consultation
If approved, the patient is placed on the transplant waiting list.
The Transplant Procedure
- General anesthesia is administered.
- A surgical team removes the diseased lungs.
- The donor lung is transplanted and connected to airways and blood vessels.
- A ventilator supports breathing post-surgery.
- Surgery may take 6–12 hours, depending on the type.
Recovery After Lung Transplant
- ICU stay for close monitoring
- Hospital stay of 2–4 weeks
- Physical therapy begins early to regain strength
- Regular spirometry to track lung function
- Lifelong medications to prevent rejection
Post-Transplant Medications
Immunosuppressants:
- Tacrolimus
- Mycophenolate mofetil
- Prednisone
These help prevent rejection but increase infection risk, so close monitoring is essential.
Common Complications
- Organ rejection (acute or chronic)
- Infections due to immune suppression
- Kidney problems from medication side effects
- Diabetes and high blood pressure
- Airway narrowing or leaks
- Osteoporosis
Regular follow-ups and strict medication schedules reduce these risks.
Life After Lung Transplant
- Most patients breathe easier and return to normal activities
- Avoid smoking, alcohol, and crowded places
- Regular exercise and healthy diet are crucial
- Monitor for warning signs like cough, fever, or fatigue
Average survival is 5–7 years post-transplant, with many living over 10 years with good care.
