The evolution of surgical techniques has rendering possible for thoracic surgery to be performed efficiently and safely, with less aggressive approaches. Being less traumatic, minimally invasive surgery allows a faster post-operative recovery, less complications and reduces in patient days and morbidity. The authors consider as minimally invasive approaches the video-assisted thoracic surgery, as well as the minithoractomy and the ministernotomy. The present paper reviews thoracic surgeries performed for the last 15 years in a cardiothoracic surgical unit using a minimally invasive surgical approach.
