Lung transplantation is a surgical operation to replace a diseased lung with a healthy one, often from a donor who has been diagnosed as having brain death. In a transplant from a living donor, not all of the lung is taken, but part of it; in some cases, the lungs are transplanted together with the heart.

Step 1

Indications for lung transplantation are diseases such as emphysema, bronchiectasis, pulmonary fibrosis, if there is no effect from the treatment, and all the possibilities of drug treatment have already been exhausted. However, very big obstacles for such an operation are its high cost and long waiting time for a donor organ. Contraindications for transplantation are severe diabetes mellitus, oncology, mental illness, severe liver and kidney disease, HIV infection.

Step 2

Before the operation, patients must undergo all the necessary laboratory and functional examinations, especially carefully the activity of the heart and lungs is examined. The operation is performed under general anesthesia, during which the patient sleeps and does not feel anything. Breathing is carried out due to artificial ventilation of the lungs using a special apparatus, patients are also connected to a heart-lung machine.

Step 3

After the patient has entered anesthesia, he is laid on his side, a roller is placed under the ribs. The surgeon makes an incision and removes the diseased lung or part of it, and then the bronchi and blood vessels are connected to the donor lung. If there are no complications, the operation to transplant one lung lasts 4-6 hours, after its completion the patient is in the intensive care unit.

Step 4

For several more days the patient breathes with the help of a ventilator until the donor lungs are sufficiently expanded. Drainage tubes are placed in the seam area so that excess fluid flows from the lungs through them. To relieve postoperative pain, pain relievers are administered intravenously. The patient should lie on his side so that the operated lung is on top; it is recommended to start physical activity as early as possible.

Step 5

After the patient has a stable improvement, he is transferred to a hospital, where he stays for an average of 2-3 weeks, antibiotic therapy is prescribed to prevent bacterial complications. To prevent rejection, immunosuppressive therapy (drugs that suppress immunity) is prescribed.

Step 6

After discharge, the patient needs frequent supervision by the surgeon performing the operation. This is done in order to identify and treat complications as early as possible. The doctor also monitors the new lungs and evaluates their function. Subsequently, a person with a transplanted lung should lead a healthy lifestyle, smoking is prohibited, and alcohol should be limited. Physical therapy and spa treatment are of great importance in rehabilitation.
