Thoracotomy is the process of making of an incision (cut) into the chest wall.


A physician gains access to the chest cavity (called the thorax) by cutting through the chest wall. Reasons for the entry are varied. Thoracotomy allows for study of the condition of the lungs; removal of a lung or part of a lung; removal of a rib; and examination, treatment, or removal of any organs in the chest cavity. Thoracotomy also provides access to the heart, esophagus, diaphragm, and the portion of the aorta that passes through the chest cavity.

Lung cancer is the most common cancer requiring a thoracotomy. Tumors and metastatic growths can be removed through the incision (a procedure called resection). A biopsy, or tissue sample, can also be taken through the incision, and examined under a microscope for evidence of abnormal cells.

A resuscitative or emergency thoracotomy may be performed to resuscitate a patient who is near death as a result of a chest injury. An emergency thoracotomy provides access to the chest cavity to control injury-related bleeding from the heart, cardiac compressions to restore a normal heart rhythm, or to relieve pressure on the heart caused by cardiac tamponade (accumulation of fluid in the space between the heart's muscle and outer lining).

The rich supply of blood vessels to the lungs makes hemorrhage a risk; a blood transfusion may become necessary during surgery. General anesthesia carries such risks as nausea, vomiting, headache, blood pressure issues, or allergic reaction. After a thoracotomy, there may be drainage from the incision. There is also the risk of infection; the patient must learn how to keep the incision clean and dry as it heals.

After the chest tube is removed, the patient is vulnerable to pneumothorax. Physicians strive to reduce the risk of collapse by timing the removal of the tube. Doing so at the end of inspiration (breathing in) or the end of expiration (breathing out) poses less risk. Deep breathing exercises and coughing should be emphasized as an important way that patients can improve healing and prevent pneumonia.
