Tracheobronchial ruptures: Classification and management [Tracheobronchiale verletzungen: Klassifikation und therapiestrategie]

Background. Tracheobronchial ruptures are rare surgical emergencies with significant mortality. We present management and outcome of such ruptures treated at the University of Leipzig in Germany and propose a novel therapeutic algorithm-a new classification system for stratifying treatment of patients with tracheobronchial ruptures. Methods. We retrospectively studied 24 patients 19 to 88 years old who were treated in our institution for tracheobronchial injury. Results. Eighty-seven percent of the injuries were caused iatrogenically. Fifty-four percent were type I injuries (isolated tracheal lesions), 38% type II (involvement of carina or main stem bronchi), and 8% type III (distal lesions of lobar or segmental bronchi). Seventy-five percent of the patients were operated via right-sided dorsolateral thoracotomy. In four (22%), insufficiency of the tracheal closure occurred, with mediastinitis possibly being a significant risk factor for this event (P<0.001). In surgically treated patients, rupture-related and overall mortality were 5.5% and 28%, respectively, whereas in medically treated patients, mortality was 33%. Conclusion. The proposed classification of tracheobronchial injuries enables stratifying the treatment of patients with tracheobronchial ruptures. Type I lesions can be surgically closed either by a right-sided thoracotomy or transcervical- transtracheal approach. In contrast, surgical management of type II and III injuries always requires thoracotomy. © Springer Medizin Verlag 2005.
