Modified schematic diagram of right TB classification (Conacher’s classification) [9]. Types I and II: the right TB is distant (> 2 cm) from the tracheal bifurcation.

Type III: the right TB is close (< 2 cm) to the tracheal bifurcation and appears as a three-branching structure. TB: tracheal bronchus
