Conventional segmentectomy and VAL-MAP-assisted complex segmentectomy. (A) A diagram of conventional anatomical segmentectomy, showing the location of a tumor close to one end of the segment, while the other side of the segment is far away from the tumor; (B) a diagram of extended segmentectomy involving adjacent subsegments (S6b and S9a) provide better resection margins than conventional segmentectomy; (C) a diagram of combined subsegmentectomy, preserving the subsegment of S8b, which is away from the tumor. VAL-MAP, virtual assisted lung mapping. The figures are reproduced with permission from Cancer Res Front 2016;2:85-104.
