Left Lower Lobe: Basilar Segments (S8+9+10)
The lower lobe comprises three basal segments: anterior (S8), lateral (S9), and posterior (S10). The main steps of the procedure are similar to those of a left lower lobectomy. The main concern is the preservation of the elements of the S6 segment, especially the superior segmental vein (V6) that can be tiny and fragile.
