What does a thoracotomy involve?

A thoracotomy specifically involves making an incision into the chest. This surgical procedure is typically performed to provide access to the organs within the thoracic cavity, such as the lungs, heart, and major blood vessels. It is often utilized in various medical situations, including lung resections, treatment of trauma, or any condition requiring intervention in that area of the body.

The other options do not accurately describe a thoracotomy. An incision into the abdomen pertains to a laparotomy, while an incision into the heart or lungs would involve more specific procedures—cardiotomy for the heart and potentially a thoracostomy or pulmonary surgery for the lungs. Understanding the precise definition and scope of each surgical term is essential for anyone in the medical field.
