Technical aspects of biportal video-assisted thoracoscopic left S1+S2 segmentectomy of the lung

The technical aspects of the biportal anterior approach for left apical and posterior segmentectomy are described. The approach is a fissure-based one. The fissure is opened and the segmental arterial branches are identified and divided. The division of the arterial branches exposed the segmental B1+2 bronchus, which is divided after lymphadenectomy. The segmental vein is not divided. Finally the intersegmental plane is completed along the inflation-deflation line.
