Video Assisted Thoracic Surgery

(video assisted thoracoscopic surgery). A surgical procedure by which small incisions are made in the chest during surgery. A small camera is placed in one of these incisions and surgical instruments are used in the other incisions in order to retrieve tissue.

This technique uses a camera to guide surgical tools into the lungs and is less invasive than traditional surgery.
