VATS is a type of minimally invasive thoracic surgery of the chest, performed with a thoracoscope (small videoscope) using small incisions and special instruments to minimize trauma. VATS procedure done under general anaesthesia, which means they are asleep during surgery. In VATS your doctor puts a breathing tube down your throat into your trachea to provide oxygen to your lungs.
Then a surgeon makes one main incision 4–6 cm and multiple additional incisions, typically 2–4 cm small incisions in your ribs and inserts specially designed surgical instruments to perform the procedure.
A high magnification scope allows you to view the cancerous lung tissue and effectively transect and remove the tissue.
