Tracheobronchial rupture due to blunt chest trauma: a follow-up study

Abstract

From 1970 to 1988, 9 patients were treated for tracheobronchial rupture arising from nonpenetrating thoracic trauma. All patients had dyspnea and pneumothorax. Four patients had rupture of the right main bronchus, 3 had rupture of the left main bronchus, 1 had rupture of the right intermediate bronchus, and 1 had rupture of the trachea. Four patients were operated on within 24 hours. Three of them had a massive air leak into the suction drainage and underwent thoracotomy. The fourth patient presented difficulties with endotracheal intubation and required a collar incision. Primary reconstruction was performed in all 4 patients. Five patients had a delay of nine to 89 days before operation. All of them had good primary healing but later developed dyspnea. Bronchoscopy revealed scar obstruction in all 5. The stenosed segment was resected in 4 patients at thoracotomy. The fifth patient, who had an intermediate bronchus rupture, underwent lobectomy. Seven patients were followed from 6 months to 18 years. One of them, who had a nine-day delay in treatment, needed further operation 6 months after the accident because of scar obstruction. The other 6 patients were interviewed, examined, and studied with spirometry, body plethysmography, bronchoscopy, and bronchography. In these 6 patients no stricture was seen, and there was no reduced pulmonary function due to the rupture even when operation was delayed.
