A pneumonectomy is the surgical removal of a lung.
Pneumonectomy is usually done as a treatment for cancer. It can be done in one of two ways:
Traditional pneumonectomy — Only the diseased lung is removed.
Extrapleural pneumonectomy — The diseased lung is removed, together with:
A portion of the membrane covering the heart (pericardium)
Part of the diaphragm
The membrane lining the chest cavity on the same side of the chest
Pneumonectomy removes half of a person's breathing capacity. For this reason, surgeons usually choose a less extreme form of lung surgery if possible.
However, a pneumonectomy is probably the best option when a tumor:
Is located in the middle of the lung
Involves a significant portion of the pulmonary artery or veins
