A 76-year-old man visited to the hospital with a complaint of cough. The chest computed tomography scan revealed a 20 mm part-solid nodule in the right lower lobe, which was suspected to be an early-stage lung cancer. Since the tumor was located in S8a, and was adjacent to S6b and S9a, thoracoscopic right S6b+S8a+S9a combined subsegmentectomy was performed. Virtual-assisted lung mapping (VAL-MAP) with indocyanine green (ICG) was performed as the preoperative marking. After dissecting the target vessels and bronchi, the intersegmental plane was identified using intravenous ICG. The pathological diagnosis was invasive mucinous adenocarcinoma with no lymph node metastasis. Combined subsegmentectomy is a useful option for the sublober resection of small lung cancer.
