[Bronchial stenosis secondary to severe thoracic contusion. Comment on 2 cases].

Two cases with complete bronchial stenosis of the mainstem bronchus secondary to thoracic blunt trauma are presented. One patient had hemoneumothorax on the left side, the other one had bilateral hemothorax. Both were initially treated with drainage by thoracostomy tube with partial resolution of the thoracic bloody pleural collection. Later, the two patients developed complete atelectasis of the lung, one on the left side and the other one in the right; this later case was subject to lung decortication. The fiberopticbronchoscopy showed a complete occlusion of the mainstem bronchus in both patients. A bronchoplasty with sleeve resection of the stenotic segment was performed; the lumen of the bronchus was preserved by an end-to-end suture with separate stitchs of Vycryl 0000. Both cases remain without bronchopulmonary pathology after 4 years of follow-up of bronchoplasty. In cases of blunt thoracic trauma, it is important to consider the possibility of bronchial rupture. The importance of bronchoscopic diagnosis and surgical treatment is stressed.
