Minimally invasive video thoracoscopic correction of pectus excavatum

Pectus excavatum, the most common congenital deformity of the chest wall, has esthetic, psychological and social repercussions as well as a slight impact on pulmonary function. Treatment is surgical and is carried out for esthetic purposes in most cases. The most commonly applied surgical technique is based on the one originally described by Ravitch: sub-perichondrial, bilateral chondrectomy and sternal osteotomy. In 1997, however. Nuss described a minimally invasive approach to correction by means of a support bar. Our objective was to perform minimally invasive correction of pectus excavatum using a substernal extrapleural approach guided by video-assisted thoracoscopy. We treated three patients over 15 years of age without surgical complications. In all three cases, the minimally invasive technique corrected the pectus excavatum with excellent esthetic results. Both the path of insertion and duration were shorter with the described approach than with traditional surgery. Video images facilitated extrapleural insertion of the bar and minimized complications.
