Thoracoscopic lateral and posterior basal (S ^{9 + 10} ) segmentectomy using intersegmental tunnelling†

Abstract

The appropriate lateral and posterior basal (S9 + 10) segmentectomy requires exposure and recognition of common basal pulmonary vein branches located deeply in the lung parenchyma. Therefore, we applied the intersegmental tunnelling method in S9 + 10 segmentectomy to recognize the dominant veins to the S9 + 10 segment accurately. Between April 2014 and December 2015, five patients underwent thoracoscopic S9 + 10 segmentectomy using intersegmental tunnelling. By using this technique, we can recognize the branches of the pulmonary vein to the affected S9 + 10 segment accurately. This technique can let us perform appropriate S9 + 10 segmentectomy.
