This patient with left upper lobe lung cancer had a high risk of pneumonectomy if resected directly due to involvement of pulmonary artery (A). However, after two cycles of induction chemotherapy, the tumor achieved significant remission (B). During the isolation of the upper lobe bronchus and the first branch of pulmonary artery, no significant invasion was encountered at the proximal portion (C, D). Finally, the procedure of lobectomy was performed without angioplasty or bronchoplasty (E).
