Key Points

The case aims to highlight the intraoperative detection and repair of a rare tracheobronchial injury caused by double-lumen tube placement.
Utilized robot-assisted thoracic surgery (RATS) for the intervention.
Identified the left main bronchus injury incidentally during lobectomy.
Reinforced the injury using a free pericardial fat pad.
Successful intraoperative identification of the bronchial injury.
Effective reinforcement with the pericardial fat pad, leading to positive outcomes.

Abstract

INTRODUCTION: Tracheobronchial injury associated with double-lumen tube (DLT) placement is rare and typically diagnosed postoperatively. Intraoperative detection of subtle airway lesions is extremely uncommon. We report a case of DLT-related injury of the left main bronchus that was incidentally detected during robot-assisted thoracic surgery (RATS) and successfully reinforced with a free pericardial fat pad.
