Successful Application of Subcutaneous Adipose Tissue With Fibrin Glue in Conservative Treatment of Tracheobronchial Rupture

An 84-year-old woman underwent aortic and mitral valve replacement. After weaning from cardiopulmonary bypass, hemorrhage was observed in the endobronchial tube. The bleeding bronchus was isolated to protect the airway using the blocker cuff of a Univent tube (Fuji Systems Corp, Tokyo, Japan). Computed tomography showed a pulmonary pseudoaneurysm in the left upper lobe. She underwent selective pulmonary angiography and embolization of the pseudoaneurysm. Bronchoscopy revealed a 5-mm bronchial rupture at the left upper lobe bronchus. The laceration was filled with adipose tissue and fibrin glue. Bronchoscopy showed a completely reepithelialized membrane, and she was discharged 38 days postoperatively.
