RUPTURE of a bronchus is not an uncommon complication following severe chest trauma. However, rarely is an antemortem diagnosis made. Most of these patients do not survive the original severe injury to the related vital organs. Hence, the opportunity for surgical repair of bronchial rupture is rarely reported. In 1949, Griffith1made the first report of a successful repair of ruptured bronchi. Subsequently, about 200 cases of both primary and delayed repair of the bronchus have been reported in Western European languages.2-9 In 1965, a primary repair of the left main bronchus of a 9-year-old boy was done four weeks following complete rupture of the bronchus. Report of Case A 9-year-old boy was admitted to Severance Hospital, Yonsei University College of Medicine on May 25, 1965, three days after he received trauma to the head and chest when he was struck by a car while riding a bicycle.
