[The treatment of the tracheobronchial stenosis by extracorporeal circulation].

Six children with tracheobronchial stenosis secondary to cardiovascular ring were operated with extracorporeal surgery. Three of them with pulmonary sling had a tracheobroncoplasty with costal cartilage, one with xiphoides appendix and another with pericardio. One girl 2 years old was operated resecting three tracheal rings and anastomosis end to end. The child that was operated with pericardio died with infection and sepsis three months after the operation. The other five are well five, four and two years after plasty.
