Tracheobronchial rupture is a rare but life-threatening injury encountered after blunt chest traumas. It is especially seen in pediatric patients because of the complete conduction of traumatic kinetic energy and the direct exposure to the airway, due to the increased elasticity of the chest wall and other anatomical structures. We report the case of an eight-yearold boy, who presented with right-sided pneumothorax, following blunt chest trauma. He deteriorated despite a thoracic drain and, during the emergency thoracotomy was finally diagnosed with a main bronchial rupture, and was treated with isolated end-toend bronchial anastomosis. The repair of right main bronchial rupture was performed with complete preservation of the right lung; the boy was discharged from the hospital on postoperative day 10, and was followed up asymptomatically for the following 32 months. This rare thoracic surgery case of pediatric patients is discussed in light of recent literature for diagnosis and surgical management.
