Detection of Incidental Tracheal Bronchus in Minimally Invasive Cardiac Surgery Planned for Single Lung Ventilation

The tracheal bronchus is a rare congenital anomaly resulting from an additional tracheal outgrowth in the early stages of embryonic life. It typically arises from the right wall of the trachea above the carina. Generally asymptomatic, it may sometimes lead to lung disease. We present the case of a 70-year-old male scheduled for minimally invasive valve surgery, where an accessory bronchus was incidentally detected during single-lung ventilation.
