In right S1 segmentectomy, an approach from the ventral side toward the dorsal side of the pulmonary hilum is commonly used; however, intersegmental veins branching from the central vein can be identified more easily on the interlobar or dorsal side of the pulmonary hilum in some cases. Additional benefits of confirming the running direction of intersegmental veins based on multidirectional views include detection of variant or aberrant vessels, as the pulmonary vein includes several anatomical variations and branching patterns. When we have difficulty in dissecting intersegmental lung parenchyma in thoracoscopic right S1 segmentectomy, intersegmental demarcation lines can be more reliably identified through the combined use of multidirectional approaches involving the pulmonary hilum rather than the use of a unidirectional approach.
