The B1 defective type of bifurcated right upper lobe bronchus.

Conclusions: The "defective B1" type of bifurcated right upper lobe (RUL) bronchus is relatively rare. A pre-operative understanding of its anatomical features, especially the vascular variation patterns, may be helpful for completing a satisfactory segmentectomy. 3D-CTBA is a powerful tool, allowing a better understanding of the pulmonary anatomy in each patient before and during surgical procedures.
