Case report: video-assisted thoracoscopic repair of right main bronchus transection after blunt chest injury.

Background: Traumatic tracheobronchial injury is a rare manifestation after blunt chest injury. The current standard treatment has wide spectrum from conservative treatment to open thoracotomy with repair airway regarding to severity of the disease. However, to the best of our knowledge, no one has reported airway repair in trauma using video-assisted thoracoscopic surgery (VATS) before. Hence, we describe the successful management and repair of a transected right main bronchus using VATS. Case Description: A 43-year-old male patient presented with chest tightness after a traumatic blunt chest injury; a chest computed tomography revealed multiple rib fractures and suspected right main bronchus injury with large pneumomediastinum and subcutaneous emphysema. Although the current standard treatment is to perform open thoracotomy with tracheal repair, we performed VATS repair of right main bronchus in purpose to reduce the stress from tissue trauma and minimally invasive fashion. Emergency surgery was scheduled for injury repair, and the transected right main stem bronchus and mediastinum hematoma were intraoperatively identified. The right main bronchus was repaired using polypropylene 4-0 interrupted sutures under uniportal VATS and covered with pericardial fat pad tissue. After the surgery, the patient had no air leak from chest tube drainage and recovered well. The patient was performed diagnostic bronchoscopy to confirm the patent airway at day 3 then discharged 7 days after surgery and was doing well at a 1-month follow-up. Conclusions: VATS repair is safe and feasible as an alternative approach to conventional thoracotomy approach in the treatment of traumatic tracheobronchial injury.
