Fig. 2From: One-lung ventilation and 3D image analysis in a case of tracheal bronchus with steeply angled branching of left main bronchus: a case reportThree-dimensional (3D) image evaluation of the airway. Entry angles from the SLT tip were 111° and 120° when the tip was placed above the TB entry (A) and tracheal bifurcation (B), respectively. Main bronchus angle was 120° (A).
