Figure 3. A case of colorectal metastases that have responded to neoadjuvant chemotherapy. The original location of the tumors is input manually into the 3D simulation to facilitate appropriate preoperative surgical planning. (A) There is a subcapsular lesion in segment 3 (labeled s3) and two subcapsular lesions in segment 6 [labeled s6 (1) and s6 (2)]. These lesions are easily accessible with a wedge resection; (B) This view demonstrates three lesions that are located in dorsal segment 8 [labeled s8 (1), s8 (2), s8 (3)], of which s8(1) and s8 (3) are subcapsular but s8 (2) is located deep; (C) S8 (2) is noted to be deep and close to the dorsal segment 8 inflow pedicle that is highlighted in green - when the dorsal segment 8 inflow is selected, its boundary is noted to encompass all three segment 8 lesions (demarcated in green in A-C). The decision is made to perform anatomical dorsal segment 8 resection, sparing the ventral segment 8 (outlined in yellow). 3D: 3-dimensional.
