Tracheal Injury Complicating Mitral Valve Repair

Intraoperative Management of Tracheal Cautery Injury in a Post-Bypass Cardiac Surgery Patient

We present the case of a tracheal injury that occurred during a Maze procedure performed via sternotomy that was not initially detected by ventilator air leak, but rather by the visual presence of gas bubbles escaping the trachea during chest irrigation. Careful investigation and machine check did reveal a subsequent air leak that would have otherwise been overlooked. Furthermore, the use of intraoperative bronchoscopy was essential in guiding and confirming surgical repair. This case underscores the need for ongoing vigilance and suggests the utility of chest irrigation with Valsalva maneuvers after procedures performed in the vicinity of the trachea to exclude injury.
