[Bronchoplasty without lung resection for the complete transection of the left main bronchus due to blunt trauma]

Blunt bronchial injury is rare but crucial injury. A 17-year-old female was admitted due to traumatic injury. She was diagnosed with bilateral lung contusion, multiple rib fractures, spleen damage and the suspicion about the complete transection of the left main bronchus on X-ray and computed tomography (CT). She was brought to our hospital at 30 hours later from injury. Bronchoscopy revealed the complete transection and the edema of the left main bronchus. She underwent a resection of the disrupted portion and end-to-end anastomosis of left main bronchus without lung resection. We should be an immediate and accurate diagnosis of tracheobronchial disruption by X-ray, CT and bronchoscopy whenever we evaluate patients with blunt chest trauma.
