Fig. 3From: Fissure-first bilobectomy of a giant lung abscess combined with a squamous cell carcinoma via a minimally invasive open surgeryA The interlobar lymph nodes were removed posteriorly to expose the posterior aspect of the interlobar PA (arrowhead). The intermediate bronchial trunk was tugged by a silk thread (arrow). B The anterior aspect of the interlobar PA (arrowhead) was exposed by dividing the middle lobe vein (asterisk) anteriorly. The upper pulmonary vein was retracted by a silicone thread. Bidirectional exposure of the interlobar PA allowed for a safe tunnel dissection of the fused fissureBack to article page
