Complex S10+S7b Segmentectomy by Pulmonary Ligament Approach Based on B7 Branching Pattern

This case may serve as a reference for surgical planning in segmentectomy for right basal lesions according to B7 branching patterns. Even in complex cases with bilateral B7 branching patterns, initial B7b dissection facilitates access to the B10. The PL approach provides not only direct access to the basal segment vasculature and bronchi but also superior visualization of the anatomy of B7 branching.
