Recently, our cardiothoracic surgery department successfully performed a bronchial rupture anastomosis for a patient with a severe chest trauma resulting in a complete rupture of the left main bronchus, and the patient has successfully recovered and was transferred to the orthopedic department for treatment of scaphoid fracture. The patient, a 48-year-old male, was admitted to the hospital on April 10 as an emergency with “chest pain, chest tightness and shortness of breath caused by heavy object pressure for more than 6 hours”. After admission, he was found to have pneumoperitoneum and blood in the mediastinum, bilateral multiple rib fractures, bilateral hemopneumothorax, contusions of both lungs, comminuted fractures of both scapulae, and contusions of the jaw and face by chest CT examination. The chief of cardiothoracic surgery, Dr. Zhao Guofang, highly suspected the possibility of bronchial rupture and performed emergency fiberoptic bronchoscopy, which revealed that the left main bronchus was completely ruptured and the rupture was about 3 cm from the tracheal bulge. It is reported that blunt injury bronchial rupture is usually seen in severe chest trauma, with a morbidity rate of 0.28-2.2% and a mortality rate of 30%. Complete ruptures are much less common clinically. Because patients often present with severe injuries, they are very likely to be missed. Prompt diagnosis and surgery can significantly improve the success rate of resuscitation.
